Now the application of metal parts, the number can be said to be very high, plus now we have so much machinery and equipment, the need for parts, or precision parts and so on, the post-processing of machinery and equipment to play a role! With the development of the market is now better and better, our science and technology is also constantly strong, now the industry needs mechanical equipment is also constantly research and development, take the packing industry, mainly our logistics, or warehouse these logistics products is very much, if it is relying on manual words, is not so fast, but with the assistance of mechanical equipment is much simpler. Now precision parts processing high precision requirements, and now the requirements of the customer has a relationship, if the quality is not good, customers will not buy, and the reputation of your manufacturers will also have an impact, if so, the late development of manufacturers, from the perspective of the above, we can do a good job of quality, processing, from the processing steps to start. Precision parts processing effect is better than in previous years, and not only in the domestic, in the export, in other countries, like Japan, or the United States, such countries, the same precision parts made by our country, indicating that the precision parts are now going international.

The emergence of intelligent products, to the industry, to the market has brought an economic boost, the expansion rate is also better than before, now manufacturers of products to choose automatic equipment processing, work speed, quality, efficiency are improved, which is also related to the development of our current society, now not only the development of intelligent products, now some hardware accessories, parts processing, CNC machining, lathe processing, or computer gong processing are automatic equipment. What are the advantages of computer gong processing compared to ordinary machine tools? 1. Machining center has high machining accuracy and stable machining quality. Machining center has the automatic tool change function, can very effectively reduce the number of workpiece clamping, reduce or eliminate the positioning error caused by multiple clamping, improve the machining accuracy. When the position accuracy of each part of the part is high, the automatic tool change function of the machining center can reduce the positioning and tool setting errors very conveniently and effectively, and can complete the machining of each part in the process of one time clamping and one time tool setting to ensure the position accuracy of each machining part.   2, can improve economic efficiency, computer gong processing machine tools, concentrated milling machine, drilling machine, tapping machine and other equipment functions, it can reduce the number of enterprise machine tools, because one person can operate more than one machining center at the same time, reducing the number of operators, labor costs are reduced accordingly; in addition to having a CNC machining center. Is also a concrete manifestation of the strength of the enterprise, will contribute to the increase in more business, thereby improving economic efficiency. 3, machining center is highly adaptable and flexible. Four-axis machining center can be easily realized on the box class parts for drilling, reaming, reaming, boring, tapping pile milling end face and grooving and many different machining processes, so it can process the contour shape is particularly complex or difficult to control the size of the parts, such as fan blades, car engine box and other parts. It can process complex curved parts and very complex three-dimensional space surface parts.   4, cnc computer gong machining center high production efficiency. Not only can eliminate the scribing, intermediate inspection and other work, but also because of its automatic tool change function, usually can also eliminate the complex tooling, reduce the installation of the processed parts, adjustment and multiple tooling and other relatively complex and tedious work. Machining center can choose the best process line and cutting amount, effectively reduce the auxiliary time in processing, thus improving productivity.

In the 21st century, machinery and equipment to improve the level of processing, cnc precision parts processing more not to mention, in the range, and in the effect more can not be less, with the expansion of the market is now faster and faster, and now the development of machinery and equipment, but the processing strength has not reached the ideal, so that to improve processing technology, or there are certain reasons, now we come to understand how cnc precision parts to improve processing technology it! Aluminum alloy is one of the most widely used non-ferrous metal materials in industry, and is used in a large number of applications in aviation, aerospace, automobile, machinery manufacturing, shipping, chemical industry and household appliances and daily necessities. With the rapid development of science and technology as well as industrial economy in recent years, the demand for aluminum alloy precision parts is increasing, which makes the CNC machining process of aluminum alloy also conduct more and more in-depth research. Pure aluminum has small density, low melting point, high plasticity, easy processing, and can be made into various profiles and plates. It has good corrosion resistance. Aluminum alloy is obtained by adding other metal elements to aluminum metal, such as silicon, iron, copper, aluminum, etc. The aluminum alloy obtained by adding other metals has the characteristics of low density, high strength, corrosion resistance, etc. Its characteristics of lightness and strength make aluminum alloy widely used in various parts processing and manufacturing, and aluminum alloy parts are widely used in industry, and in life. The wide application of aluminum alloy has promoted the development of CNC machining technology of aluminum alloy, and the development of CNC machining technology has expanded the application field of aluminum alloy, so CNC machining technology of aluminum alloy has become a hot spot for research. Aluminum alloy parts machining, also known as CNC machining, automatic lathe machining, CNC lathe machining, etc., its characteristics are used in turning, milling, planing, drilling, grinding and other general-purpose machine tool processing mold parts, and then the necessary clamp repair, assembly into a variety of molds; high precision requirements of mold parts, only with ordinary machine tool processing is difficult to ensure high processing accuracy, and therefore need to use precision machine tools for processing; in order to make the mold parts, especially the complex shape of the convex mold, concave model holes and the mold parts. parts, especially the complex shape of the convex mold, concave model hole and cavity processing more automated, reduce the workload of the clamp repair, the need to use CNC machine tools (such as three-coordinate CNC milling machine, machining center, CNC grinding machine and other equipment) processing mold parts. CNC cutting is a kind of processing method that makes cutting more rational, and is also a common process of aluminum alloy precision machining, using end mills with multi-directional cutting function, spiral cutting interpolation and equal height tangential interpolation, etc. It uses as few tools as possible to process a small number of holes. The unique advantage of CNC machining of aluminum alloy precision parts is that the ball end mill with helical interpolation method can be used for continuous processing of tapered holes; the use of ball end mills and helical interpolation drills can be used for boring and chamfering; end mills with contour tangential interpolation can be used for semi-finishing and precision parts processing of holes; end mills for processing threads with helical interpolation method can be used for processing various threaded holes.

Precision machining in the range, and in the effect, efficiency are better, and technical processing to manufacturers to bring the benefits of the road to development will be smoother, the wider the market expansion, the greater the development space, and now we will understand the benefits of precision machining! First of all, many parts themselves have certain shortcomings, for example, the appearance of some can not meet the requirements, some of the scope of application there are certain restrictions, in short, these parts themselves are a certain defect, in the use of the process will bring their own industrial production of certain problems and problems, after precision machining parts can be very good to overcome these problems, so as to tap the unique value of the parts themselves.   Many medium-sized parts also need to be assembled, so precision machinery parts processing manufacturers will be for such needs for reprocessing, a variety of different parts after processing we can get more suitable for their parts, so in order to make these products better for their own service, so precision machining to life and production with a pivotal significance. Hardware machinery parts also have the product surface or shape can not meet some of the corresponding requirements, will also use this workpiece for processing. This process is generally carried out on the parts through precision turning, grinding and other operations. Often can make those non-ferrous materials to form a certain surface of the parts surface, such as we often say the mirror effect. Mechanical parts production after the process of processing the shape of the parts structure can also meet the requirements of the drawings of the shape tolerance, can be a good solution to industrial production to bring some problems.

The application of metal parts, screws, or nuts, the application of other accessories, mainly because the machinery and equipment is increasing, you see the current aerospace technology, or the application of CNC equipment, mold parts processing, are aided by machinery and equipment, the overall role is more obvious, improve the processing speed, to bring manufacturers a certain benefit, which is still relatively good. Engaged in machining, high-precision mechanical parts manufacturing, the selection of blanks to determine, not only affect the economy of the manufacture of blanks, but also affect the economics of machining. So in determining the blank, both the hot processing aspects, and economic considerations, but also to take into account the requirements of cold processing, in order to determine the blank from the link, reduce the manufacturing cost of parts. First, castings: complex shape of the parts blank, it is appropriate to use casting methods of manufacture. Most of the current castings with sand casting, which is divided into wooden mold manual modeling and metal mold machine modeling. Wooden mold hand-shaped castings with low accuracy, processing surface allowance, low productivity, suitable for single-piece small batch production or large parts of the casting. Metal mold machine molding high productivity, casting accuracy, but the high cost of equipment, the weight of the casting is also limited, suitable for mass production of small and medium-sized castings. Second, a small number of small castings with high quality requirements can be used for special casting, such as pressure casting, centrifugal manufacturing and investment casting. Second, forgings: mechanical strength requirements of high steel parts, generally to use forging blanks. Forgings are free forging forgings and die forgings of two kinds. Free forging forgings can be manually forged (small blanks), mechanical hammer forging (medium-sized blanks) or press press forging (large blanks) and other methods to obtain. The accuracy of such forgings is low, the productivity is not high, the machining allowance is large, and the structure of the parts must be simple, suitable for single and small batch production, as well as the manufacture of large forgings. The accuracy and surface quality of the forgings are better than the free forgings, and the shape of the forgings can also be more complex, and thus can reduce the machining allowance. The production efficiency of die forging is much higher than that of free forging, but it needs special equipment and forging die, so it is suitable for small and medium-sized forgings with larger batch size. Third: Profiles can be divided into: round steel, square steel, hexagonal steel, flat steel, angle steel, channel steel, I-beam and other special cross-sectional profiles according to the shape of the section. There are two types of profiles: hot-rolled and cold-drawn. Hot-rolled profiles have low precision, but are inexpensive and used for general parts of the blank; cold-drawn profiles are smaller in size and high in precision, easy to achieve automatic feeding, but higher in price, mostly used for batch production and suitable for automatic machine processing. Fourth, welded parts: welded parts are obtained by welding method and the combination of parts, the advantages of welding is simple manufacturing, short cycle time, saving materials, the disadvantage is poor vibration resistance, deformation, need to be processed by aging before mechanical processing. Reasonable choice of machinery manufacturing precision parts of the blank, not only to save material costs, and can save a lot of processing time, improve production efficiency.

The use of precision equipment processing, the effect will be better, how to say it, the first from the processing effect, and then to the processing efficiency is also much faster, plus now the intelligent equipment is increasing, automation is more and more obvious, so that now computer gong processing, or and milling machine processing on the technical requirements are also increasingly high, now we come to understand the computer gong processing it! Computer gong processing is in the processing of products, the choice of digital control system on the computer configuration, set more accurate processing and production, compared with traditional mechanical processing, modern computer gong processing power or quality is better than the traditional manual hand board. With the continuous development of computer technology, processing equipment can handle the processing of more parts at the same time, CNC equipment, now has a great integration advantage than before, become the mainstream form of processing now. CNC hand board strengths are reflected in its ability to very accurately reflect the information expressed in the drawings, and CNC hand board appearance of high quality, especially after its completion of the exterior coating and silk screen printing, even more than the production of open molds The product is even more glorious than the one produced after the mold is opened. Therefore, more and more people choose CNC hand board processing production is not without reason. 1, CNC hand plate processing parts precision and surface roughness: if the need to 0.05mm tolerance requirements, regardless of processing equipment or hand plate master, the requirements are relatively high, the cost will also be relatively high; 2, CNC hand board is processed parts material if it is difficult to process materials, such as stainless steel, material hardness, the need to use tungsten steel hardened tools, and computer gongs need to be Taiwan or Japan machine with to do, of course, the cost will also be higher than with ordinary material processing. 3, CNC hand plate processing parts structure and size: if the product structure is complex, processing costs will be much higher; if the overall size of the product or appearance is curved shape, processing costs will also rise a lot.

If in the process of selection, there is a factor is not selected accurately, then certainly will directly affect the final product effect, so in the selection of each one should be carefully selected, the choice of CNC system function suitability for CNC machine design selection is undoubtedly an important limiting factor. The first thing to consider is its drive capability, different CNC suppliers of solutions in the servo power range and supporting motor range is also different. First of all, the initial screening should be done from the type of motor that can be matched, the power range. In particular, we should pay attention to whether the CNC machine tool program includes torque motors, linear motors, electric spindles are synchronous electric spindles or asynchronous electric spindles, the rated current requirements of the above motors and overload current requirements, the electric spindle speed requirements. Five-axis machine tools need to clarify whether five-axis linkage or only requires five-sided processing, the corresponding choice of CNC system features are different. For example, for five-sided box-type processing, usually do not need RTCP, the choice is relatively large. At the same time for the five-axis function may involve CNC system suppliers in the export license, after-sales service, etc. must also be carefully considered. Most of the CNC machines launched by machine shops, especially large and heavy CNC machines, have fully closed-loop and dual-drive requirements. In the fully closed-loop control scheme, to choose between distance encoding encoder, ordinary incremental encoder, while the CNC system should also support the corresponding feedback signal access. CNC system networking support to become a necessary condition for the integration of production systems, for to be incorporated into a high degree of automation of the production system of CNC machine tools, it must be clear that the CNC system has the appropriate access solutions, including low-level relying on PLC input and output points directly into the CNC system built-in OPC server, in accordance with the OPC standard to open up the internal data of the CNC system to the user; in addition to production-oriented systems, the Automated online workpiece detection and tool detection is also a function that must be supported.

In the process of processing there must be some with is what we should pay attention to. Because in the work, a lack of attention will easily lead to problems, problems will directly affect the quality of the product, so in order to avoid these things happen, then we have to pay attention to the time of production. And so the problem must be timely solution, but before the solution must first find what is the reason in the solution, then we will understand the following mechanical parts processing in the cause of deformation is what? 1, the effect of internal force incurred parts processing accuracy changes Lathe processing, usually is the application of the effect of centripetal force, with the lathe's three-jaw or perhaps four-jaw chuck, the parts stuck tight, and then the mechanical parts to stop processing. At the same time, in order to ensure that the parts are not loose when the force, reduce the effect of internal radial force, it is necessary to make the clamping force is greater than the mechanical cutting force. Clamping force increases with the increase of cutting force, and then decreases and decreases. Such an operation can make mechanical parts in the process of processing force stability. However, after the three-jaw or perhaps four-jaw chuck release, the machined mechanical parts will be far from the original, some present polygonal, some present oval, present a large bias. 2, heat treatment processing after the simple deformation problem On the sheet type of mechanical parts, due to its long diameter is very large, in its stop after the thermal treatment is simple to present the straw hat meandering situation. On the one hand, it will present the phenomenon of the middle bulge, the plane deflection increases, on the other hand, due to the influence of various external factors, so that the parts produce meandering phenomenon. These deformation problems are not only due to the heat treatment of the parts after the onset of stress changes, and the operator's professional knowledge is not solid, not quite understand the structural stability of the parts, and then increase the probability of parts deformation. 3, the effect of external forces caused by the elastic deformation There are several main reasons for the elastic deformation of parts in machining. First, the internal structure of some parts, assuming that they contain a thin sheet, will have higher requirements for the operation method, otherwise the operator in the parts to stop positioning and clamping, can not stop corresponding with the planning between the drawings, simple incurring elastic deformation. Second, the lathe and fixture is not flat, so that the parts in stopping the fixed both sides of the force is not even, resulting in cutting the force effect of the small side of the force will be presented under the effect of translation present parts deformation. Third, the positioning of the parts in the processing process is not reasonable, so that the rigid strength of the parts is reduced. Fourth, the presence of cutting force is also one of the causes of the elastic deformation of the parts. These different causes of the elastic deformation, all clarify the effect of external forces on the quality of machining of mechanical parts. These points are the causes of deformation in the machining of mechanical parts, mechanical processing function is not only related to the interests of enterprises, but also related to the safety, in order to bring economic benefits to enterprises at the same time, but also can help reduce the probability of safety accidents. So safety is very important

Now metal processing, or hardware processing, are special machinery and equipment, work is also much more convenient, and than manual work to do a lot faster than the efficiency, if you say what mechanical equipment, the number of manual work is not able to keep up with the current development, now machinery and equipment can be said to be all over the industry, baling machines, packaging machines, folding machines, cranes, forklifts and other such equipment, in now can be said to use such as flow   In the time of precision machining, the choice of materials if not powerful enough, then, it may lead to the processing of the parts can not meet the needs of mechanical equipment, because of this, when processing must be clear about the material requirements of the relevant situation! If the metal material for processing, then, depends on how hard it is, in many metal materials, stainless steel is the hardest, while cast iron is slightly second, copper hardness in cast iron, while the hardness of aluminum is the lowest, so the workpiece on the hardness requirements should choose stainless steel, while the requirements of low should choose aluminum.   1, first of all, to understand the hardness requirements, some places use the equipment on the hardness requirements of the parts is the higher the better, but this is generally only in the processing of the workpiece hardness requirements, if the processing material, then, the hardness generally can not be too hard, or it may lead to the material is too hard and affect the normal work of the machine parts.   2, then, to see what the specific role of the processed parts, if it is used in some high-temperature industry, then, the choice of material must be high-temperature resistant material, and used in some other industries, then, in accordance with industry requirements to choose the right material on. The above is precision machining on the material requirements of the relevant content, in short, it is on the material in addition to hardness requirements, there are other requirements, specific requirements must be combined with the situation to determine, or it may not meet the requirements and lead to the production of the workpiece can not be used.
