As an important embodiment of a country's industrial level and comprehensive national strength, the progress of machining is accompanied by the development of many high-tech and emerging industries. At the same time, the development direction of machining also fully reflects the characteristics of the times that advanced manufacturing technology is becoming increasingly intelligent, flexible, networked, precise, green and globalized. Equipment manufacturing, an important component of machining, provides important material support for the development and production of new technologies and products. There are several major development trends in the machining industry. Understanding these trends will be of great help to gain a foothold in this industry. Localization of basic equipment In the machining industry, machine tools, cutting tools, fixtures, testing instruments, etc. are all basic equipment, and the quality of basic equipment determines the level of machining to a great extent. However, there are many key parts in basic equipment. At present, China cannot produce them by itself, but must rely on imports. This is a constraint to the development of China's mechanical processing industry. In the future, the state will actively promote the localization of infrastructure equipment and get rid of import dependence. Advanced processing technology Developed countries use more advanced processing methods and technologies, such as high-precision processing, fine processing, micro processing, nano processing, laser processing, electromagnetic processing, superplastic processing and composite processing, to complete some processing effects that are difficult to achieve with traditional technologies. China is still catching up in this regard. With the development of science and technology, especially the rapid development of electronic technology and information technology, more and more high-tech will be applied to the machining industry to help realize the upgrading of advanced processing technology. Automation technology becomes mainstream Developed countries have entered the transitional stage from automatic processing to intelligent processing, and we need to further consolidate the achievements of automation upgrading. In China, with the development of computer technology and other high-tech, as well as the popularity of automatic processing equipment, the degree of automation of the mechanical processing industry has also been greatly improved, and automatic processing will become the mainstream. In the future, machining enterprises will make more use of CNC machine tools, machining centers, flexible manufacturing units, flexible manufacturing systems, and computer integrated manufacturing systems to realize flexible automation, intelligence, and integration of machining. New management concepts such as just in time production, agile manufacturing, lean production and concurrent engineering will also be widely recognized and applied. Master core technology and innovation ability Since the reform and opening up, it has been a normal phenomenon for foreign enterprises to invest in China and domestic enterprises to introduce foreign technology, which has driven the domestic economic development and manufacturing prosperity to a great extent. However, simply attracting foreign investment and introducing technology cannot help us master core technology, let alone improve our innovation ability. In the future, China's manufacturing industry must make breakthroughs in core technology and innovation ability in order to form its own competitiveness. Increase the proportion of science and technology investment At present, China is not a "manufacturing" country, and the proportion of science and technology investment in our GDP is still very low. According to statistics, in 1960, the proportion of China's science and technology investment in GDP reached a small peak of 2.32%, and then decreased year by year before 2000, only 0.69% in 1998. Although it has rebounded since 2000, it has remained at a few percentage points. In innovative developed countries and newly industrialized countries, this proportion is usually more than 2%. Therefore, it is an inevitable trend for China to further increase investment in science and technology in the future. Cultivation of independent innovation talents The improvement of innovation ability of machining enterprises depends on the cultivation of excellent talents. At present, the general situation is that the technological innovation ability is poor, the product development cycle is long, and the top innovative talents are also extremely limited, and there is a serious shortage of high-level talents, leading to the lack of technological innovation. In the future, the cultivation of independent innovation talents in the machining industry will be a major guarantee for the development of the industry and will be promoted to an important position.

After the pursuit of high-speed machining and high-speed cutting, the NC machining industry has entered the track of pursuing efficient machining. Efficient machining does not overemphasize the fastest cutting speed or the highest machining quality, but emphasizes improving the metal removal rate per unit time, so as to achieve the purpose of Improving NC machining efficiency, machining performance and machining efficiency. This is the optimization of the whole processing and manufacturing process, so as to achieve a higher output input ratio. Although the overall level of China's manufacturing industry has improved in recent years, there is still a large gap between China and developed countries in terms of efficient processing, mainly in the following aspects. Lack of independent innovation ability Compared with the R & D and innovation capabilities of developed countries, China is still at a low stage in the production of efficient CNC processing equipment, mainly imitation. And this imitation is only the imitation of the shape of the equipment, lacking the internal core functions and advantages. The lack of independent innovation ability leads to the lack of unique design ideas, exquisite manufacturing technology and assembly technology of the equipment we produce. In most cases, it is not a real high-performance processing equipment. High end equipment is excessively dependent on imports Because we cannot innovate independently and produce high-end and efficient processing equipment with stable operation, such equipment in China mainly depends on imports. Moreover, some developed countries promote each other through knowledge sharing and technology sharing, but impose strict technology blockades on developing countries. This leads to the fact that China has to rely on its own strength to develop in the case of a low starting point of research and a late start of development. This is also one of the reasons why the equipment is excessively dependent on imports at this stage. Low level of key functional components The key components of high-efficiency processing equipment, such as screw, guide rail, spindle, grating ruler, gear rack, worm gear, etc., also play a key role in processing. Therefore, it is an important basis to measure whether the high-efficiency processing equipment is really efficient. At present, although these key components can be produced in China, they cannot meet the requirements in function, because their core technology is still mastered by developed countries. If this state is still maintained, it will be a great constraint for China's efficient processing equipment manufacturing enterprises. Backward processing and assembly technology If I get the drawings of foreign advanced equipment, can I produce equipment with the same quality and function? I'm afraid the answer is No. Because of the gap between processing technology and assembly technology, it is difficult for us to meet the requirements of the drawings. Therefore, at this stage, China's machinery manufacturing enterprises need to solve not only the design problems, but also the processing technology and assembly technology problems in the production of efficient processing equipment. Only with all-round progress in these aspects can we truly have our independent production capacity of high-end equipment. Insufficient basic research strength Domestic manufacturing enterprises generally do not pay attention to the reserve of basic research strength, and the R & D strength is insufficient, so it is difficult to provide valuable research results. The long-term reference and imitation led to the further disconnection between its basic theory and practical application, which seriously failed to keep up with the trend of international development. Domestic enterprises also have various problems, such as insufficient attention to professional talents, imperfect talent training mechanism, lack of talent competition mechanism for sustainable development, which makes it difficult for those talents with skills to give full play to their strengths, resulting in brain drain or related technology interruption.

Someone once said that the real economy and manufacturing are the foundation of other industries. Although in the past few decades, the manufacturing industry has led China's economic development to a new level, with the passage of time, the manufacturing industry has gradually become inadequate and fell into a "dilemma", which makes manufacturing enterprises and employees very distressed. So, what is the reason why China's manufacturing industry is in trouble? 1、 All costs are rising No matter how the manufacturing and machining industries are analyzed, the rising cost has always been the primary reason. First, with the rise of human capital, capital expenditure has increased by 12% - 15% every year. Raw materials rose, and the prices in the first half of the year and the second half of the year were quite different. Other expenses, such as rising gas, water and electricity bills, are exacerbating the difficulties of manufacturing development. Moreover, the rise in house prices has led to the rise in factory rental prices, coupled with the cost of logistics, each of which is very distressing for small and medium-sized manufacturing enterprises. 2、 Financing difficulties Rising costs require more money. Banks have a lot of requirements in terms of lending, and it takes a long time to wait for approval. Generally, after the loan is approved, the managers of machining enterprises also think of other ways to raise money. Most of the money borrowed by this "other way" has high interest, so the direct result is that the cost is increased again and the profit is reduced. 3、 Labor transfer Many employees on the production line of manufacturing industry will switch to other jobs because of low wages. However, due to the pressure of its own loans, the manufacturing industry is unable to bear the high wage standard of employees. Therefore, the manufacturing industry is short of people but unable to employ people, which has brought many problems to the development of machining enterprises. 4、 Damage of the real estate industry to the real economy One data shows that China's GDP was 67trillion last year, and the income from land sales was 3.4 trillion. Among the house prices, the land price mainly accounts for 30%. At the same time, coupled with intermediaries, decoration, household appliances and furniture, it also drives other related industries. In this way, real estate investment accounts for more than 45% of GDP. It can be seen that the impact of real estate on the manufacturing industry is not just rent. 5、 Low social status In China, people engaged in the real economy are often ridiculed by people engaged in emerging industries. Moreover, many people will feel that the manufacturing environment is dirty and messy, and the boss's quality is low. In fact, the real situation is not the case. In China, manufacturing has created many jobs and maintained 70% of China's labor force.

Nowadays, people are advocating the spirit of craftsman, which is because the spirit of craftsman to carve and improve their products is needed by everyone. It is this spirit that improves the accuracy of products and enables people to use high-quality products. Many people believe that the spirit of craftsman can only be used for manual processing. In fact, it is not. In machining, there is a process that can also achieve the spirit of craftsman, that is, laser processing. Laser machining was born in 1963. Because of its advantages of less cutting, good precision and high degree of automation, it is widely used in machining production. Laser processing refers to the processing of metallic or non-metallic materials with high-energy laser beams. According to different mechanisms, it can be divided into two categories: one is the process of using materials to absorb laser energy for processing, such as cutting, welding, drilling and surface heat treatment. The other is the processing process using photochemical reaction and accompanying thermal effect, such as laser etching, doping and oxidation. In actual production, laser processing is mainly used for cutting, welding and surface modification, which has many advantages: 1. High precision: the laser beam can be focused. The focused laser beam is a very small spot, which can make the processing achieve high precision, and the heating deformation of the workpiece is small. When cutting, the slit width is very small. 2. Avoid pollution: laser processing does not have direct mechanical contact with the workpiece, so it will not produce environmental pollution in the process of machining and gas processing, and it can also realize precision processing in special environments. 3. Strong penetrability: because the laser will not be weakened by other factors when passing through the air, it can be processed in various environments or completed in vacuum. And it can also penetrate the workpiece shell directly to the interior for some special processing. 4. Wide processing range: laser processing can not only be used for the processing of general materials, but also has a good effect on some extremely hard, brittle and high melting point materials. It is of great help to realize automation, improve production efficiency and improve accuracy. Therefore, laser processing has better economic benefits than other processing. 5. Laser welding does not need solder: this kind of welding can effectively avoid pollution, which is very helpful for some products with strict requirements, such as medical devices, food utensils, etc. With the development of science and technology, laser processing is also advancing. People have seen the advantages of laser processing, and will vigorously develop and promote laser processing technology in the future.

With the concept of industry 4.0 put forward, more and more machining enterprises use CNC machine tools for processing and manufacturing. Many enterprises also use semi-automatic or full-automatic machines to replace manual processing and production, which not only promotes the development of the machining industry, but also saves human and material resources. However, for small and medium-sized mechanical processing plants, due to the lack of financial strength, most of their hardware products are processed or produced by non-standard machinery. However, with the development of science and technology, many small and medium-sized enterprises also realize the importance of automatic processing of non-standard machinery for production. This paper will specifically analyze the advantages of using automatic mode of production of non-standard machinery processing equipment. 1. Reduce labor costs With the improvement of talent quality in China, the cost of human resources has also increased, and the human cost problem previously ignored by many enterprises has gradually become one of the important costs of enterprises. Using automatic mode or semi-automatic mode to produce non-standard hardware products can reduce the annual employment and recruitment of enterprises, so as to focus on cultivating high-end technical talents, improve the professional quality of employees, and directly reduce the annual and monthly human and material expenditure of the company. 2. Improve production efficiency The automatic mode or semi-automatic mode can ensure the accuracy and quality in production, and it is much more efficient than traditional manpower, and there will be no problems such as leave, absenteeism or labor, physical exhaustion and so on. 3. Reduce the probability of industrial accidents In the process of machining, it is easy for operators to cause health hazards due to improper operation. Using automatic mode or semi-automatic mode for production, setting up procedures for automatic operation of machinery, and implementing man-machine dialogue through interphone and display screen can greatly reduce the accident rate of industrial injury and ensure the efficiency of machining. 4. Improve product quality and stability, and the maintenance rate of equipment is low The quality of products is the foundation of an enterprise. Using automatic mode or semi-automatic mode of production can ensure the accuracy and quality of products. Automatic equipment production can be debugged, monitored and operated simply. Moreover, automatic or semi-automatic equipment has self-test procedures, which can also monitor the occurrence of accidents in real time, helping operators to repair in time. 5. Environmental protection, energy saving and long service life of equipment The automation equipment is driven by servo motor and operates in gap, so it can save oil and electricity to a certain extent, and has the advantages of environmental protection and low noise.

Machinery manufacturing is a strategic industry providing technical equipment for various industries. It has the characteristics of high industrial relevance, good absorptive capacity, technology and capital intensive. However, due to the rapid economic development, the development speed of machining enterprises lags behind seriously. In order to change this phenomenon, the machinery manufacturing industry needs integrated ideas, current technology, product innovation, management mode and product innovation, which is also the future development direction of the machinery manufacturing industry. Today's increasingly fierce market competition makes machining technology supported and promoted. The whole operation process of manufacturing industry includes decision-making, product design, process design, manufacturing and processing, sales, after-sales service and other links. Today's manufacturing technology includes management technology, design technology, manufacturing technology and so on. For China, the future development direction of machinery manufacturing industry should not only have strong manufacturing capacity of light-duty products represented by household appliances and electronic components, but also have strong manufacturing capacity of heavy-duty heavy equipment represented by power generation equipment, metallurgical and petrochemical equipment and automobile production equipment. To achieve this goal, we need to pay attention to the achievements of high-tech technology in the application of manufacturing industry. We should take the innovative spirit of providing equipment for the development of high-tech technology and the integration of manufacturing industry and high-tech technology as the core. It has strong manufacturing capacity of new high-tech equipment represented by microelectronics, optoelectronic manufacturing equipment, MEMS and bioengineering. This will constitute a new growth point of manufactured products in the new era, and it is also the core of the competition in the equipment manufacturing industry in developed countries, as well as the key to maintaining technological competitive advantage over other countries. In addition, green intelligent manufacturing is also the inevitable direction of the development of strategic machinery manufacturing industry. It refers to a modern intelligent manufacturing model that comprehensively considers environmental impact and resource efficiency on the premise of ensuring function, quality and products. It can make the whole process of products from design to manufacture and then to scrap not produce environmental pollution, or minimize the pollution and meet the requirements of environmental protection. In the production process of products, resources and energy are effectively saved, so that the utilization rate of resources is the highest and the energy consumption is the lowest. At the same time, intelligent manufacturing is also a man-machine integrated intelligent system composed of intelligent machines and human experts. It can not only liberate human beings, but also carry out scientific analysis, reasoning, judgment, conception and decision-making. Let the automation concept of mechanical manufacturing expand to flexibility, intelligence and high integration. Therefore, in the new round of manufacturing development, machinery manufacturing can only catch up with the rapid development of the economic situation by combining with advanced technology and constantly launching new products and fine products.

In the manufacturing industry, the word industrial Internet of things is not unfamiliar to everyone, and the industrial Internet has gradually become a key link to realize smart factory and intelligent manufacturing, which shows the importance of industrial Internet of things. How to deploy and establish the industrial Internet of things has become a problem that every machining enterprise needs to consider. This article will tell you how to deploy the industrial Internet of things. Why is the industrial Internet of things so advocated nowadays. In fact, its real advantage is not in the system upgrade, but through the development of constant data to collect and evaluate the continuous improvement efficiency of the feedback loop, and provide the necessary information for the industrial Internet of things strategy. For the construction of industrial Internet of things. The first thing we should do is: 1. Define goals The main goal of deploying the industrial Internet of things is to reduce costs and improve efficiency (related reading: how to improve production efficiency in the process of tool use), or to achieve remote monitoring of systems and processes. When the target is determined, we can analyze the components according to the existing equipment and data. This process is very important. In most cases, it is impossible to replace all the old equipment, and the cost is too high. Therefore, in practice, machining enterprises prefer to integrate communication equipment and protocol conversion software to connect all systems, so as to make effective use of existing equipment. 2. Device connection The Internet of things is a "network", so to realize connection, enterprises must connect machines and sensors from different manufacturers. For old equipment without communication ability, sensors can be integrated for processing, and a sensor network can be strategically re deployed to meet the requirements of data collection. When the device completes the connection and realizes the communication between devices, we should also consider how to push the data. The real power of industrial Internet of things and cloud computing comes from data centralization and integrated applications to extract and process information. Many industrial IOT platforms now provide databases with data storage time processing, equipment supply and reporting capabilities. Although they are usually configured for specific applications, many of them are built for simple and rapid implementation. 3. Remove obstacles In the industrial Internet of things, privacy and security are important obstacles to investment in the industrial Internet of things. When collecting and transmitting sensitive data, it must be protected. Therefore, the industrial Internet of things should take special security measures to ensure that the system can safely collect, monitor, process and store data. However, to ensure security, we need to solve the balance between time, resource related costs and data protection.

With the emphasis on environmental protection in China, cleaner production and sustainable development have become one of the issues that must be considered in the production process of machining enterprises. Then, in view of the environmental protection of production and processing in the industrial industry, let's analyze the things related to environmental protection, cleaner production and sustainable development. Machining production and environmental protection In machining production, waste residue, noise and other pollution often cause serious harm to nature and human body. In the provisions of environmental protection, it mainly defines the destruction of production resources and environmental pollution. 1. Destruction of ecological resources: environmental problems caused by the direct effect of human hot work on the natural ecosystem, which significantly reduces its production capacity and significantly changes its structure. 2. Environmental pollution: harmful substances or factors enter the environment and diffuse, migrate and transform in the environment, which changes the structure and function of the environmental system and adversely affects the survival and development of human beings and other organisms. Machining production and sustainable development 1. Ecological sustainable development: pursue development without exhausting resources, destroying ecology and polluting the environment, and maintain harmony between human beings and nature. 2. Sustainable economic development: strive to reduce resource consumption, reduce waste, improve efficiency, and implement cleaner production and civilized consumption. 3. Social sustainable development: it should not only reflect the fairness of contemporary people in the distribution of natural resources and material wealth, but also reflect the fairness between contemporary people and future generations; While considering their own development, contemporary people should leave room for the development of future generations. Machining production and cleaner production 1. Cleaner production process (1) Effective use and substitution of raw materials: reduce the toxicity of raw materials or reduce their use. (2) Reform process and equipment: simplify process flow, optimize process parameters, and develop new processes and equipment. (3) Improve operation and strengthen management: improve boring storage methods and strengthen material management. (4) Product reform and substitution: recovery and regeneration of product scrap, development of Wuhai products (5) Internal recycling in the production system: decompose the recovered waste into raw materials for reuse in the production process. 2. Cleaner production products (1) Selection of raw materials: we should use less scarce raw materials, use more waste or recycle boring, and try to use less or no toxic raw materials. (2) Manufacturing: reduce processing procedures, simplify technological processes, and seek to minimize waste in the production process. (3) Use and consumption: in the process of use and consumption, we should try to reduce the consumption of resources and the emission of pollutants. (4) Scrap disposal: after scrap disposal, it should be easy to recycle, take or decompose, degrade and disperse its waste components in the environment. The concept of cleaner production should not only contain technical feasibility, but also be economically profitable, reflecting the unity of environmental benefits, economic benefits and social benefits.

In recent years, the development of China's industry has encountered a bottleneck, and the economic benefits are far behind the real estate and Internet industries. Facing this problem, China's industrial manufacturing sector needs new impetus to promote development and restore its leading position in the development of the national economy. If you want to develop the industrial manufacturing industry, you must first understand what restricts the development of industry. Taking the cutting tool industry as an example, China has a great lack of technological innovation. Using "shape is like God but not like God" can well describe the current situation of cutting tools in China. Once, Chinese enterprises imitated the products of foreign excellent enterprises, or imitated among the same industries. Although there were slight changes on the basis, it was only in the primary stage, not technological innovation. Imperfect R & D system At present, there are still many defects in the enterprise management foundation of the tool industry. Many management problems have accumulated for a long time and cannot be effectively solved, which has become the key to seriously restrict the development of China's tool industry. Among them, the management of R & D system is particularly serious. Compared with foreign tool enterprises, Chinese enterprises have a big gap in the establishment of R & D centers, project management, personnel selection, and personnel incentives. Moreover, the lack of guidance from the R & D team based on the industry strategy cannot break through the key difficulties, resulting in the backwardness of R & D and the gap with foreign enterprises. Unstable R & D environment The tool industry includes many knowledge fields, such as matrix material design, tool appearance structure design, coating organization structure design, special digital technology development and so on. Any field can affect the change of the whole tool industry. Similarly, in the production line, the lack of any link related to technology will lead to the instability of tool product performance. Therefore, in order to change this situation, we need to make systematic accumulation of tool R & D and effective planning of each link, so as to know the actual production and ensure the stability of products. Insufficient innovation ability The common problem in the field of industrial manufacturing in China is the lack of innovation ability, which is more profoundly reflected in the tool industry. Many tool manufacturers only focus on the interests of low-end products, stick to the rules, and dare not face market reform. At the same time, they are also unwilling to increase the investment in new equipment and new processes for new technologies, lack the patience to study the market, excessively imitate the new products of other enterprises, blindly follow the market, and ignore the saturation of the market. Lack of supporting services China's tool industry has great deficiencies in market application and service level. Although the tool products are complete, they are only limited to production. China's standard cutting tools have been in a notified position in the market for a long time, and the idea that cutting tool enterprises and users are only a simple business relationship occupies a large part. Therefore, a large part of the domestic tool industry has no service force and service awareness. This leads to poor user experience and poor competitiveness with foreign brands. In view of the current situation, it is suggested that enterprises engaged in industrial manufacturing and domestic machine tool enterprises should pay attention to innovation and technology. In the face of fierce competition in the international market, in order to keep up with the pace of international development, it is necessary to break the conventional existing research and development ideas, develop from the perspective of customers, and make products with core competitiveness.

Nowadays, with the development of science and technology, precision machining can no longer meet the needs of people, and more and more enterprises begin to study ultra precision machining. Ultra precision turning of diamond tools is mainly used to process soft metal materials, such as non-ferrous metals such as copper and aluminum, some alloys and non-metallic materials, and has achieved good results in practical applications. Therefore, the development prospect of diamond tools is very broad. Advantages and development of ultra precision turning of diamond tools 1. Develop towards higher precision, high efficiency and large scale Large optical lenses are essential in various technical fields, such as laser and fusion, synchrotron radiation technology, and the research and development of large astronomical telescopes. Therefore, the workpiece requiring ultra precision turning is gradually larger, and the requirements for machining accuracy are also increasing. With the stability of ultra precision machining quality and the sharp increase in the number of ultra precision machining parts, foreign ultra precision turning machines are developing towards high efficiency. Improving productivity generally starts from two aspects: increasing spindle speed and feed speed, and shortening spindle start and stop time. 2. Adopt computer compensation technology to improve machining accuracy All kinds of relevant parameters that lead to the decline of machining accuracy are measured in advance. Through calculation, processing and compensation, the accuracy higher than that of machine tools can be obtained. This development trend has been paid more and more attention. Because it is limited to improve the machining accuracy only by improving the accuracy of reference components. For example, the guideway straightness of some ultra precision machine tools has reached 0.025/1000000, and it is difficult to improve its accuracy. Computer compensation is needed to solve the problem. 3. Integration of processing and measurement The components of ultra precision machining machine tools have high accuracy. If some appropriate instruments are configured or certain measures are taken, they can be used as measuring devices. In this way, processing and measurement can be combined, so that processing and measurement can be carried out at the same time, and processing can be carried out under monitoring conditions, so as to realize the integration of processing and measurement and improve economic benefits. 4. Developing modular ultra precision lathe Using different ultra precision machine tool elements and components to form various types of ultra precision lathes is conducive to reducing costs and shortening the manufacturing cycle. Users can put forward requirements according to needs, and obtain the required machine tools at a lower price and in a shorter time. Shortcomings of ultra precision turning of diamond tools However, in ultra precision machining, diamond tools can not process every material. For ultra precision cutting of ferrous metals, diamond tools are not so perfect. Because the diamond turning tool wears fast in the cutting process, which destroys the stability of the machining process, it can not guarantee that the machined parts have ideal surface roughness and geometric accuracy. It is generally believed that natural diamond turning tools are not suitable for ultra precision cutting of ferrous metals, but in actual production, there are some steel and other difficult to machine material parts with complex shapes and high precision requirements. Therefore, in recent years, people began to study the ultra precision turning of diamond in brown metals. No gold is enough, no man is perfect, and so is diamond cutter. Although the performance of refined steel stone tools in ultra precision machining is excellent, they can not be processed in all metals. Therefore, people are constantly studying and discussing how to apply the performance of diamond in ultra precision machining to all metals. If you want to know more about precision machining, please pay attention to the hook net to bring you newer, faster and more effective machining knowledge.
