How to choose a manufacturer for machining

We often listen to our friends talking about how to choose suppliers, especially the suppliers of machining! There are thousands of suppliers, and the best is the one that suits you. We focus on quality, price, delivery date and service. No one who does procurement is bothered by honest machining suppliers. Cooperation is about integrity! Answer the phone in time and return the information in time. Give a positive and sincere response and understand the work process. We can continue our cooperation. Quick screening: a reliable one-stop machining cloud platform. How to choose the manufacturer for machining? Let's listen to the statement of the quick add online purchasing: Factors affecting supplier selection Suppliers are part of the open system of supply chain, so the choice of suppliers is also affected by various economic, policy and other factors. 1. Quality factors Quality is the foundation of supply chain. The use value of a product depends on the quality of the product. It determines the quality of final consumer products and affects the market competitiveness and market share of products. Therefore, quality is an important factor in selecting suppliers. 2. Price factor The low price means that the company can reduce the production and operation costs, which has a significant effect on improving the competitiveness and increasing profits of the company. This is an important factor in selecting suppliers. However, the supplier with the lowest price is not necessarily the most suitable, and factors such as product quality, delivery time and transportation cost should also be considered. 3. On time delivery factor Whether the products can be delivered on time and at the agreed time and place directly affects the continuity of the company's production and supply activities. It will also affect the inventory level of the supply chain at all levels, thus affecting the reaction speed of the company to the market, interrupting the production plan of the producer and the sales plan of the seller. 4. Variety flexibility factor In order to survive and develop in the fierce competition, the products produced by the company must be diversified to meet the needs of consumers, achieve the purpose of occupying the market and obtaining profits. Product diversification is based on the flexibility of supplier varieties, which determines the type of consumer goods.

Is low price competition the "magic weapon" of machining enterprises?

Competition is an inevitable behavior among enterprises. The goal of an enterprise is to achieve profits and create value, and competition is inevitable in the process of achieving profits. Maintaining a good competitive relationship between enterprises can help enterprises update technology, improve services, and provide consumers with more affordable and high-quality products; On the contrary, improper competition will lead enterprises into the abyss or even to extinction. Coincidentally, in the machining industry, improper competition is often seen, such as low-cost competition. We often see such scenes. Some machining enterprises are proud to publicly show off the low price of their own parts processing. In their mouth, cheap seems to be the best marketing means and can be used to boast. As long as the parts processing is cheap enough, there will be no customers. Therefore, we can not help asking: is low-cost competition really a shortcut for the machining industry? It is true that a lower price can help enterprises obtain more sales, but it does not mean that it will bring more profits. Machining itself is a low profit industry, and the net profit of most enterprises remains in a very low range. Now, repeated price reduction leads to a decrease in the net profit of a single order and the profit owned by the enterprise, which will inevitably lead to a series of problems such as material selection, production process and quality control. If the capital chain at a certain place breaks, the whole enterprise will collapse instantly. Therefore, low price competition is like walking on a tightrope. From the perspective of R & D and improvement of processing technology, the enterprise's research and development expenses or introduction expenses in the early stage of machine tools are a huge expenditure. Machine tool enterprises in Europe and Japan are technologically advanced because of their long R & D cycle and sufficient R & D costs. The R & D expenses come from the profits of the products. We rarely see these countries rely on low-cost competition to attract customers. It is also because reducing the profits will affect the capital investment in R & D, production and other aspects. Therefore, the development of an enterprise depends on a good cycle of input and output. It's only enough to listen to the low profit that is still boasting of its tens of millions of R & D. Of course, low-cost competition does not necessarily mean low profits. Some machine tool enterprises are "taking the lead" in low-cost competition. These manufacturers use inferior mechanical parts to replace regular mechanical parts and seek profits at low prices. However, this practice is actually cheating consumers. As long as consumers find problems in using products, they will lose trust in the enterprise. Once the trust disappears, consumers will no longer choose the products of enterprises, and what is more, machining enterprises will have to take legal action. In addition to the above problems, there is another legacy of low-cost competition, which is the impact on the brand. When users think that your brand is cheap, even if the quality rises significantly, the price can hardly be significantly increased. When we go to the mall, we often see two kinds of slogans, one is "promotion and discount" and the other is "refuse to bargain". Even if the "promotion and discount" shop is like a market in the past two days, it often changes its store in the next two days. On the other hand, the "refuse to bargain" shop is not like a market, but it wins in the long stream and continues to develop with excellent quality. The same is true in the machining industry. Although low-cost competition can attract a large number of users in a short time, this method is difficult to last, and there are many "sequelae". For machining enterprises, compared with low-cost competition, good business strategy, active R & D investment and excellent machining quality are the right way. Nowadays, many domestic machining one-stop platforms have emerged: for example, quick screening is superior to traditional machining plants in terms of machining quality, delivery time and service awareness.

Analysis of 3D printing midstream equipment manufacturing enterprises

This paper takes the mid stream enterprises of 3D printing (3D printing equipment manufacturing enterprises) as the starting point, analyzes them with PEST analysis, five force model and SWOT model, and makes a deep analysis on the mid stream enterprises of 3D printing from the macro and micro levels, and puts forward relevant development suggestions on this basis. At present, 3D printing furniture in China is developing rapidly with the support of the state, while 3D printer manufacturing enterprises, as the midstream furniture of 3D printing, are facing a unique background and environment. For 3D printer manufacturing enterprises, how to achieve sustainable development in the face of the current social environment is an extremely important proposition. Under this background, the author makes an in-depth analysis of 3D printing manufacturing enterprises by using relevant management models 1、 External macro environment analysis - PEST analysis (1) political environment With the rapid development of 3D printing furniture, "3D printer", the main carrier of 3D printing furniture, has entered the golden age of research, development and sales. The quality and advancement of 3D printer skills will directly affect the development of 3D printing furniture in China. Therefore, in recent years, the Chinese government has issued a number of policies to support the development of 3D printer manufacturing enterprises, and a large number of policies to support the progress of printer skills have followed. Recently, the High Tech Department of the Ministry of science and technology organized experts to fully listen to the opinions of various parties and reach a broader consensus. They listened to the opinions and suggestions of the business community in Nanjing, and conducted a more in-depth discussion on the development strategy of China's 3D printing manufacturing skills, which has become a preliminary development idea. At the meeting, the expert group introduced the "preliminary considerations on the development strategy of 3D printing technology in China". Representatives from 12 enterprises, including aerospace No. 8 Research Institute, Shenyang aircraft, Shaanxi Hengtong, Beijing Longyuan, Wuxi Yiwei, Shanghai Lucheng, Shanghai Aowei and Suzhou Xinjian, from the additive manufacturing furniture technology innovation alliance, had a heated discussion on the development prospects of furniture, current problems, opinions and suggestions on scientific and technological affairs, Actively offer advice and suggestions. According to insiders, the preliminary consideration on the development strategy of 3D printing technology in China is expected to lay a foundation for the introduction of 3D printing related household property policies, and the concept of 3D printing is expected to usher in favorable policies again. At the same time, there are various signs that 3D printing is being promoted to the level of national strategy. In order to accelerate the development and localization of 3D printing manufacturing skills, the Ministry of industry and information technology is brewing top-level design and overall planning, and formulating special policies to support the development of 3D furniture. Insiders believe that with the key support of the state, China's 3D printing furniture will usher in a new round of development opportunities. Through scientific research and development and equipment nationalization, China has changed the situation where such equipment relied on import in the early stage. More than 20 service centers have been established throughout the country, and equipment users are all over the medical, aerospace, automobile, military industry, mold, electronics and electronics, shipbuilding and other industries. In 2011, the scale of China's additive manufacturing household goods market was nearly 1 billion yuan (excluding the military industry market). With the overall upgrading of China's manufacturing industry and the promotion and application in medical treatment, aerospace, automobile, military industry, consumer electronic products, geographic information, art design, mold and other industries, the additive manufacturing market will further expand. There is no doubt that 3D manufacturing enterprises will benefit from the policies of the Chinese government and realize a new round of progress. On the one hand, 3D printer manufacturing needs a certain entry cost, and the formulation of relevant policies, such as software and hardware support of jiadang Park and bank credit support, will provide a "green channel" for the establishment of printer manufacturing enterprises. On the other hand, 3D printing is a household property with high skill requirements and fast updating. The implementation of the government policy has provided economic assistance and skills training for the R & D of enterprises, and opened up a channel for the introduction of advanced technologies in the world. In short, with the support of the policy, China's 3D printer manufacturing industry will breed beautiful flowers in the fertile soil cultivated by the country. (2) economic environment The growth of China's economic level has provided a good environment for the midstream enterprises of 3D furniture. Initially, the acceleration of industrial transformation and upgrading in China was conducive to the rapid expansion of 3D printing market demand. In recent years, with the rapid rise of the cost of land, labor and other factors, China's industrial transformation and upgrading is becoming more and more urgent. Under this background, the pace of industrial transformation and upgrading in China will be further accelerated. The demand of Chinese enterprises for shortening the life cycle of new products and improving the product design ability is constantly increasing, and the 3D printer manufacturing industry is very suitable for the needs of industrial transformation. Therefore, the demand for 3D printing equipment with product design and prototype development will increase from time to time, and the economic environment is suitable for the development of 3D midstream enterprises. In addition, the rapid development of aerospace and national defense industry has increased the demand for 3D printing equipment from time to time. China is in the period of rapid development of aerospace and national defense industry. Aviation equipment, satellites and applications have been included in the national strategic emerging industries for key support. 3D printing skills such as laser near net forming will have great development space in the manufacturing of complex and difficult to process aircraft and satellite parts. From historical experience, it can be concluded that the time of economic recession is the time when new economy sprouts and new skills are born. The reason why the global economy is sluggish proves that the traditional production relations have hindered the development of productive forces, and reform will become a new driving force for production development. American scholar Jeremy Rifkin said that the combination of the Internet and new energy will produce a new round of industrial revolution. The economist pointed out that the market potential of 3D printing skills is huge, and it is bound to become one of the many breakthroughs that will lead the future manufacturing trend. At present, the application of 3D printing skills in the fields of mass consumption, industry and bioengineering has been at the beginning, and has a different degree of household wealth. In Europe and the United States, the popularity of 3D printing is higher than that of China. In 2012, the output value of the world 3D printing industry was 12 billion to 13 billion yuan, while that of China was about 1 billion yuan. The output value of 3D printing in the United States and Germany accounts for about 80% of the total revenue of the industry. China's market size is very similar to that of Japan, but China is considered as one of the most potential countries in 3D printing with its booming national economy and huge population base, which is conducive to the continuous progress of the printer manufacturing industry. (3) social environment (1) Printer market expansion As far as the current social environment is concerned, most of the current 3D printer enterprises have grown up by expanding the users of indicator enterprises. Enterprise users have always been important target customers of 3D printer manufacturers. However, a large number of ordinary people were initially interested in 3D printing. This concern not only shows that more and more people have initially recognized the existence of 3D printing and made their own preliminary judgments on its functions and principles; This enthusiasm also shows that more people are now trying to explore the mystery of 3D printing, and are eager to witness the magic effect of 3D printing, personally realize the operation of 3D printer, and personally experience the changes that 3D printing has brought to the real world from virtual to reality. In this case, more and more 3D printer manufacturers initially focused on the market of small household printers, and developed a development route of producing and researching personalized small printers. For the several 3D printer manufacturers surveyed by our team, the small printer market accounts for half of the market share of these enterprises. With the advancement of quality education, many primary and secondary schools are trying to provide students with better educational environment and better educational opportunities. In this context, the laboratories of primary and secondary schools have also become the key market of small printers. In addition, the pursuit of printers by individual enthusiasts has naturally become a driving force of the 3D printer market. (2) Increase in marketing channels In recent years, network skills have become more and more popular, and e-commerce has developed rapidly from an unprecedented speed. The network economy has different laws and modes from the traditional economy. The characteristics of e-commerce decide that it is much better than the traditional commerce. It has the characteristics of low marketing cost, easy to collect and manage customer information, especially in line with the sales of information goods. Therefore, network marketing has developed on the basis of e-commerce. Network marketing is a combination of indicator marketing, direct marketing, decentralized marketing, customer-oriented marketing, two-way interactive marketing, remote or global marketing, virtual marketing, paperless trading and customer participation marketing. It is a revolution of skills and means, and contains a deeper concept revolution. As a "superconductor" medium for trans space-time transmission, the Internet can provide punctual services for customers' locations. At the same time, the interactivity of the Internet can understand customers' needs and provide targeted responses. Therefore, the Internet can be said to be the most attractive marketing tool in the information age. Network marketing endows marketing combination with new connotation. In recent years, some large-scale 3D printer manufacturers at home and abroad have embarked on the road of e-commerce and achieved initial results. With the increase of marketing channels, 3D printer manufacturers have more opportunities to communicate with customers, and these manufacturers can conduct marketing to customers more comprehensively, in-depth and on time. Therefore, the increase of marketing channels also provides development opportunities for midstream enterprises of 3D printing furniture. (4) skill environment 3D printing is a revolutionary skill rising in recent years. 3D printing has a wide range of applications and broad prospects. Theoretically, when the 3D printing technology is mature, with the addition of different printing materials, it can print anything, including human organs (raw materials are cells), buildings (raw materials are building materials), machinery (raw materials are metals), and so on. As long as the model to be printed is depicted on the computer, it can achieve a very high degree of recovery. Traditional manufacturing skills such as injection molding can produce large quantities of polymer products at low cost, while 3D printing skills can produce relatively small quantities of products in a faster, more flexible and lower cost way. A desktop size three-dimensional printer can meet the needs of the designer or the concept development team to manufacture models. Because 3D printing equipment is revolutionary, and the research and development of 3D printing technology is very sufficient in the world, 3D printer manufacturing also has a sufficient technical foundation. At the same time, China has taken innovation driven development as a national strategy to transform the development mode and accelerate industrial transformation and upgrading, and the R & D of skill innovation and home-based application has been strengthened from time to time. As a new household property, 3D printing has excellent conditions for skill innovation. At present, there are fewer and fewer restrictions on the manufacture of printers, which are initially shown in the materials of 3D printers. Although high-end industrial printing can realize the printing of plastics, some metals or ceramics, the materials that cannot be printed are relatively expensive and scarce. Researchers are trying to use more and more cheap and easily available materials to make 3D printers, and have made great progress in the field of multi-material printing. In addition, the volume and quality of printers are also moving towards lightweight. 3D printer manufacturers can now produce one or even several small printers in one day, which can not only meet the market demand but also reduce the time. At the same time, the number of 3D skilled personnel is rising from time to time. Because the debugging of 3D printer occupies a large proportion of the manufacturing process, and this part often needs the monitoring of professionals. Therefore, the increase of 3D manufacturing employees and the improvement of skills also provide excellent conditions for the development of 3D printer manufacturers. 2、 Industry competition analysis: Five Forces Model 1. Analysis of the buyer's bargaining power Under the current circumstances, the 3D printer market can be said to be a blue ocean market, but also an incomplete monopoly market. Buyers who want to buy 3D printers have only a few printer manufacturers to choose from. This means that the printer manufacturer has a strong voice in front of the buyer, while the buyer's bargaining power is very weak. Basically, the pricing standard is determined by the 3D printer manufacturer, and the buyer can only choose to accept it to a large extent. However, if 3D printer enterprises want to quickly open the market, they still need to adopt strategies such as price reduction to a certain extent to occupy the blue ocean market. 2. Analysis of suppliers' bargaining power At present, the manufacturing of 3D printers requires some high-end positioning, superior quality and some special materials. For some materials, 3D printer manufacturing is an important buyer. Once the price increase exceeds the acceptance range of 3D printer manufacturers, they choose other suppliers instead, which will cause great loss to the suppliers of 3D printer enterprises. Therefore, the bargaining power of suppliers of 3D printer manufacturing enterprises, the midstream enterprises of 3D printer manufacturers, is low. 3. Competitiveness analysis of potential entrants As far as the midstream enterprises of 3D printing household belongings are concerned, there may be situations where their upstream and downstream enterprises expand the household belongings chain and erode the midstream enterprise market. At the same time, after accumulating rich capital and experience, some foreign 3D printer manufacturers in Daxing palace may enter the Chinese market and become potential entrants in the middle of the 3D printer chain. However, as a new revolutionary household property, domestic 3D printing is supported by national policies and has local advantages. All these have created high barriers to new entrants for potential entrants. If these two types of enterprises try to enter the 3D printer manufacturing industry, it will be difficult to avoid high entry costs and high failure risks. Therefore, the competitiveness of potential entrants in the 3D printing chain is weak. 4. Competitiveness analysis of substitutes Although the emergence of 3D service intermediaries represented by 3D printing shops will cause certain resistance to the sales of 3D printers. However, from the current sales situation of ordinary printers, although there are countless printing shops everywhere, many companies and individuals with large demand for printing business still have strong demand for printers. Therefore, we can speculate that even with the emergence of some 3D service organizations, 3D printers can still thrive and suffer little impact. 5. Competitors in the same industry Take Nanjing Baoyan Automation Co., Ltd. as an example. It has the R & D team of Nanjing Normal University in terms of skills. At the same time, the company has long-term cooperation with some high-tech furniture bases in the United States, so it has unique advantages in updating skills. In addition, in cooperation with universities in Nanjing, such as Nanjing University and other institutions of higher learning, it can tap high-quality 3D printer talents and provide sufficient skilled personnel support for the measurement, control and R & D of its printers. As a result, Baoyan has become a leader in the 3D printer industry in Nanjing and even the whole country. Therefore, if the 3D printer manufacturing enterprises have advantages in skills, supplemented by marketing and capital support, they will greatly reduce the threat posed by their peers. 3、 Suggestions on the development of 3D printing midstream Enterprises 1. Adopt multi-channel marketing strategy to develop E-commerce With the popularization of network skills and the rapid development of e-commerce, in recent years, some large-scale 3D printers at home and abroad have embarked on the road of e-commerce and achieved certain results. The increase of the marketing channels of the marketing channels enables 3D printer manufacturers to have more opportunities to communicate with customers, and also enables these manufacturers to conduct marketing to customers more comprehensively, more deeply and more punctually. Therefore, the increase of marketing channels also provides development opportunities for midstream enterprises of 3D printing furniture. It is imperative for 3D enterprises to develop e-commerce and conduct multi-channel marketing. At the same time, for the current 3D printing midstream enterprises, the proportion of individual customers is increasing, which means that the small, household and personal printer business will become an important business of the printer manufacturing enterprises in the future, and the small printer is also very consistent with the realization of logistics transportation. 2. Make use of policy advantages to realize large-scale production 3D printer manufacturing, the midstream household belongings of 3D printing household belongings, is currently the sunrise household belongings in China

3D printing makes up for the shortcomings of traditional manufacturing

3D printing has had a great impact on the manufacturing industry. The long-term development of 3D printing is bound to be the weakness of traditional manufacturing, which provides opportunities for 3D printing to expand. We may get a glimpse of this from how the traditional manufacturing industry operates! How does traditional manufacturing work? Traditional craft: from designer to manufacturer How to turn an idea into reality? This has been an ancient story for decades. Engineers design parts and determine their shape, materials and other factors, so that a basic prototype can be manufactured. However, when it comes to manufacturing end-use parts, engineers must find a manufacturer that can make the parts meet professional standards and scale. Parts can be designed anywhere, but manufacturing these parts requires a lot of machines. According to the manufactured parts, the manufacturer can use any number of manufacturing processes to manufacture. They can be machined in which a large piece of metal is cut into a desired size and shape; They can bend and stamp the metal sheet into a new shape; They can produce large numbers of parts from liquid plastics using molds or tools. Traditional manufacturing processes like this are very useful and will continue to be used for many years. However, they also have their own shortcomings. Weaknesses of traditional manufacturing industry 1) Waste; 2) Additional equipment; 3) Skilled labor. One of the most common traditional manufacturing technologies is "subtractive manufacturing". The most common form of subtraction manufacturing is CNC machining. However, although subtractive manufacturing is good for processing high-quality materials, it is not always effective. In addition, traditional manufacturing processes often require additional equipment. The casting process requires some things, such as molds and molds, which require time and money to manufacture, but when the work is completed or reaches its life, they will eventually be discarded. Finally, the actual installation and operation of these traditional manufacturing systems is a small problem. Traditional machines usually occupy a large floor area, which leads to the demand for large factory space, which requires a large amount of money to rent or buy. Although some processes (such as numerical control machining) are controlled by computers, many processes require skilled machinists to operate them manually. All these problems have become obstacles for enterprises to enter the traditional manufacturing industry. Let's take a look at 3D printing What is one of the biggest advantages of 3D printers? They can be built almost anywhere and are relatively easy to operate, so that small businesses can start printing products without the need for specialized manufacturers to help them. At the same time, large manufacturers began to widely implement high-end printers to make prototypes and professional parts. How does 3D printing affect the world today? Multiple applications Although stereoscopic printing is still widely used, 3D printing now includes a wider range of technologies that can be used to print plastics, metals and other materials. The absolute range of technology and price means that 3D printing is now widely used in various industries, including automobile, aerospace, medical care, consumer goods, design and fashion.

Material requirements for CNC precision parts processing

CNC precision parts processing is not suitable for precision processing of all materials. Some materials are too hard and exceed the strength of the processed parts, which may lead to the collapse of equipment parts. Therefore, this material is not suitable for precision machining, except for equipment parts made of special materials or laser cutting. The requirement is specific to each work, because it will also endanger the quality of the equipment produced. Therefore, to maintain the quality of the equipment, it is necessary to have requirements not only for the machinery and equipment, but also for the use of employees and some processing equipment. Materials are required. There must be certain specifications for this. Only in this way can the finished product be the ideal one. Let's learn about the material requirements for CNC precision parts processing? CNC precision parts processing materials are divided into metal materials and non-metal materials; For metal materials, stainless steel has the highest strength, followed by pig iron, followed by copper, and finally aluminum. The processing of porcelain and plastics belongs to the processing of non-metallic materials. For material strength requirements, in some places, the higher the strength of the material, the better, but it is only the strength requirements of the processed parts. The processing materials should not be too hard; If it is harder than mechanical parts, it is difficult to process; The material must have moderate hardness and softness. It is at least one level lower than the strength of parts, and also depends on the function of the produced equipment and the effective selection of equipment. In the manufacturing process of CNC precision parts, the manufacturing requirements and standards of each part are different, and the manufacturing process scheme is also different. When different process options are used to manufacture the same parts, the productivity and economic benefits are different. Shenzhen pfiter Precision Products Co., Ltd. focuses on: CNC precision processing supporting services for aviation, medical equipment, auto parts and other equipment accessories. Processed materials: aluminum alloy, stainless steel, magnesium alloy, titanium alloy, nickel base alloy, brass, bronze, engineering plastics and other special difficult to process materials. Processed products: precision machinery parts, medical precision parts, aviation parts, auto parts, alloy parts, hardware shells, radiators and other high-standard products in the industry.

What are the key technologies of machining, and what is the most important?

As the most important advanced manufacturing technology in mold manufacturing, high-speed machining is an advanced manufacturing technology with high efficiency, high quality and low consumption. A series of problems in conventional cutting have been solved by the application of high-speed machining. The cutting speed and feed speed are improved in series compared with the traditional cutting process, and the cutting mechanism has also changed fundamentally. Compared with traditional cutting, high-speed machining has made a substantial leap. The metal removal rate per unit power is increased by 30% ~ 40%, the cutting force is reduced by 30%, the cutting life of the tool is increased by 70%, the cutting heat left in the workpiece is greatly reduced, and the low-order cutting vibration is almost eliminated. With the increase of cutting speed, the removal rate of blank material per unit time increases, the cutting time decreases, and the processing efficiency improves, thus shortening the manufacturing cycle of products and improving the market competitiveness of products. At the same time, the small amount of fast forward of high-speed machining reduces the cutting force, and the high-speed removal of chips reduces the cutting force and thermal stress deformation of the workpiece, and improves the possibility of cutting poor rigidity and thin-walled parts. Due to the reduction of cutting force and the increase of rotation speed, the working frequency of the cutting system is far from the low-order natural frequency of the machine tool, and the surface roughness of the workpiece is most sensitive to the low-order frequency, thus reducing the surface roughness. In the machining process of the high hardened steel parts (hrc45-65) of the mold, the use of high speed can replace the process of electrical machining and grinding and polishing, avoid the electrode manufacturing and time-consuming electrical machining time, and greatly reduce the amount of grinding and polishing of the fitter. High speed milling can be successfully completed for some thin-walled die workpieces that are more and more needed in the market. Moreover, on the high-speed milling CNC machining center, the mold can be clamped once to complete multi-step machining. These advantages are very suitable for die and mould industries with fast capital turnover requirements, urgent delivery time and fierce product competition. High speed machining system is mainly composed of high-speed machining center, high-performance tool clamping system, high-speed tools, safe and reliable high-speed cam software system, etc. Therefore, high-speed machining is essentially a large system engineering. With the development of cutting tool technology, high-speed machining has been applied to the processing of alloy steel (HRC > 30), and is widely used in the processing of stamping dies, injection molds and other parts in automotive and electronic components. The definition of high-speed machining depends on the type of workpiece material being processed. For example, the cutting speed used for high-speed processing of alloy steel is 500 m / min, which is the conventional down milling speed when processing aluminum alloy. With the expansion of the application scope of high-speed machining, the research on new tool materials, the improvement of tool design structure, the generation of new CNC tool path strategies and the improvement of cutting conditions have also been improved. Moreover, the computer-aided simulation technology of cutting process has also appeared. This technology is of great significance for predicting the temperature and stress of cutting tools and prolonging the service life of cutting tools. The application of casting, stamping, hot pressing and injection molding represents the expansion of the high-speed application range of cast iron, cast steel and alloy steel. In the manufacturing of stamping dies and casting molds, the industrial leading countries spend most of their research and development time on machining and polishing processes. The machining and polishing of stamping die or casting die account for about 2 / 3 of the total processing cost, and high-speed milling can be used to shorten the development cycle and reduce the processing cost. The reason why high-speed is more and more widely used in industry is that it has significant advantages over traditional processing. Specifically, it has the following characteristics: (1) The production efficiency is effectively improved. High speed machining allows a large feed rate, which is 5-10 times higher than that of conventional cutting, and the material removal rate per unit time can be increased by 3-6 times. When a large number of metal parts need to be cut, the processing time can be greatly reduced. (2) Reduce cutting force by at least 30%. Due to the extremely shallow cutting depth and narrow cutting width adopted at high speed, the cutting force is small. Compared with conventional cutting, the cutting force can be reduced by at least 30%. This can reduce the machining deformation for parts with poor machining rigidity and make it possible to cut some thin-walled fine workpieces. (3) The processing quality is improved. Because the excitation frequency of tool cutting is far from the natural frequency of the process system during high-speed rotation, the forced vibration of the process system will not be caused, and a good machining state is ensured. Because the cutting depth, cutting width and cutting force are very small, the deformation of the tool and the workpiece is small, the dimensional accuracy is maintained, the cutting failure layer is thin, the residual stress is small, and the machining with high accuracy and low roughness is realized. From the perspective of dynamics, it can be seen that the reduction of cutting force will reduce the amplitude of vibration (i.e., forced vibration) generated by cutting force; The increase of rotation speed makes the working frequency of the cutting system far away from the natural frequency of the machine tool to avoid resonance; Therefore, high speed can greatly reduce the surface roughness and improve the machining quality. (4) Reduce processing energy consumption and save manufacturing resources. Due to the high metal removal rate per unit power, low energy consumption and short manufacturing time of workpieces, the utilization rate of energy and equipment is improved, and the proportion of cutting processing in the total resources of the manufacturing system is reduced, which meets the requirements of sustainable development. (5) The process flow is simplified. Conventional cutting cannot process quenched materials, and quenching deformation must be manually trimmed or solved by electrical discharge machining. High speed can directly process quenched materials. In many cases, the EDM process can be completely eliminated, eliminating the surface hardening problem caused by EDM, and reducing or eliminating manual finishing.

Development trend of automatic lathe processing in the future

Automatic lathe machining is the development of science and technology in recent years. Enterprises that use a large number of mechanical processing need a large number of human resources for instrument lathe processing. The wide application of automatic lathes has greatly improved the efficiency of product lathe processing, reduced the manpower and material resources, generally one person can watch more than one table, reduced the labor intensity of workers, and greatly improved the work efficiency. Different from the general lathe, it is a kind of automatic operation effect realized by cam and cam lathe. For many years, the development has been the history of convex wheel automatic lathe. The production of walking watch parts machine comes from Switzerland, and gradually develops to tool walking machine. Japan has also played a great role in the development of automatic lathe. The precision of automatic lathe has made an indelible contribution to the improvement of machining accuracy. Up to now, many mechanical processing enterprises are still processing on this instrument lathe. Although this kind of instrument lathe is cheap, it requires a lot of manual operation, low production efficiency, low processing accuracy, large processing volume of small parts, low processing efficiency, low processing accuracy, high labor cost and low enterprise efficiency. As a small part, the mechanical part has a high degree of automation compared with the meter lathe. For example, in the processing of small copper parts, one worker can operate multiple automatic lathes, and the unmanned operation can almost reach a long time. The capacity of the automatic lathe parts per minute can be measured several times by the instrument lathe, and the processing of small parts is very suitable.

What are the categories of machining errors

Machining error refers to the deviation degree of the actual geometric parameters from the design ideal value. The smaller the machining error, the higher the machining accuracy. Let's first look at the categories of machining errors. 1. Dimensional error It is the deviation degree of the actual size of the part from the ideal size after processing. The ideal dimension refers to the average value of the maximum and minimum limit dimensions marked on the drawing, that is, the center value of the dimensional tolerance zone. 2. Shape error It refers to the difference (or deviation degree) between the actual surface shape of the processed part and its ideal shape, such as roundness and straightness. 3. Position error It refers to the difference (or deviation degree) between the surface, axis or symmetry plane of the processed part and its ideal position, such as axial degree and positional degree. 4. Surface micro unevenness The apparent geometric error on the machined part surface, which is composed of small spacing and peaks and valleys. The micro unevenness of part surface is expressed by the evaluation parameter value of surface roughness. Machining error is caused by many error factors in the process system. Such as the principle error of machining method, workpiece clamping and positioning error, fixture and tool manufacturing error and wear, machine tool manufacturing, installation error and wear, machine tool and tool error, force, thermal deformation and friction vibration during cutting, as well as geometric error of blank and measurement error during machining.
