In fact, in our industrial industry, this is still relatively common, but for some laymen, may not be too familiar, but learn to use the people will not necessarily know what his role is, this is still to understand ourselves, of course, in the process of our work will slowly know some, then the following we will understand the role of non-standard parts processing in the end what it is! The role of non-standard parts machining center is a highly efficient, high-precision CNC machine tools, the workpiece in a clamping can be completed in multiple processes, but also has a tool library, and automatic tool change function. Non-standard parts machining center can realize three axes or more than three axes of linkage control to ensure that the tool for complex surface processing. In addition to linear interpolation and circular interpolation, the non-standard parts machining center also has various machining fixed cycles, automatic compensation of tool radius, automatic compensation of tool length, graphic display of machining process, human-machine dialogue, automatic fault diagnosis, off-line programming and other functions. The role of non-standard parts machining of non-standard parts machining center is developed from the CNC milling machine. The biggest difference with the CNC milling machine is that the machining center has the ability to automatically exchange processing tools, and by installing different tools for different purposes on the tool magazine, the processing tools on the spindle can be changed in one clamping by the automatic tool changing device to achieve a variety of processing functions. The role of non-standard parts processing of in industrial production, involving materials, processes, costs, the use of the number of issues, there are many parts can not be mass production through the machine, so that it is necessary to carry out small-scale or small non-standard parts processing through certain special processes, the middle may also involve manual processing links. Generally, we mainly use CNC, rapid mold, vacuum silicone re-mold and other processes to achieve small batch production.

There are definitely a lot of things to pay attention to when processing, there are also many factors that affect the quality of the product, so we must pay attention to some of the details of the above issues, so let's learn about the following precision machining requirements of the material what? 1. first is the requirement of material hardness, for some occasions, the higher the hardness of the material is the better, but only limited to the hardness requirements of the processing machine parts, the processing material can not be too hard, if harder than the machine parts can not be processed. 2. Secondly, the material is soft and hard, at least one grade lower than the hardness of the machine, but also depends on the role of the processed device is to do what with a reasonable selection of materials for the machine parts. In short, precision machining requirements of the material or some, not what material is suitable for processing, such as too soft or too hard material, the former is not necessary for processing, and the latter is impossible to process. Therefore, the most basic one is, before processing must pay attention to the density of the material, if the density is too large, equivalent to the hardness is also very large, and if the hardness is more than the hardness of the machine parts (lathe turning tool), it is impossible to process, not only will damage the parts, but also cause danger, such as turning tool flying out of the crash injury. Therefore, generally speaking, for mechanical processing, the material material should be lower than the hardness of the machine tool, so that it can be processed.

In fact, many factors have a great relationship with the parts parts parts parts, because in the process of operation are closely related. If there is a problem, it is normal to directly affect the quality of the entire product, so a small detail of the problem should also pay attention to. Here we come together to understand the precision of machining and what factors are related to it? The production of manufacturers and machinery and equipment have a relationship, with the help of machinery, our workload, the effect, speed are much faster. Although it is said that the help of machinery and equipment, but the face of the customer's quality requirements for the product so high. Natural in the processing process of high precision requirements, such as precision mechanical parts processing. When precision mechanical parts are machined, digital program-controlled contouring systems are widely used on milling machines, including simple, reliable and inexpensive phase systems with a wide range of process capabilities. These systems are used in many factories, especially for controlling large three-dimensional profiles for precision mechanical parts machining. Correctly programmed control is one of the main conditions to ensure the quality of machining of precision mechanical parts. For digital program-controlled phasing systems, the preparation of the control program is carried out by using an automatic program preparation system, the level of quality of which depends to a large extent on the price of preparing the control program. Others are the processing errors that arise when manually controlling the equipment, and these include accidental and systematic errors of the process system. All processing errors in the system error plays a major role, for precision mechanical parts processing as a whole, will cause a series of CNC process system errors. For example, gaps, the consequences of which are like insensitive bands in the machine tool drive chain, but do not include reverse drive chain gaps; amplification factors for unstable drives; phase errors on the control program tape; . Periodic stepping instability of the sensor feedback, the main form of which is the phase form of instability. Here to remind you: If a problem occurs, first we need to find the cause of the problem so that we can better solve the problem. Otherwise not found the reason is not only to increase the difficulty of the solution, if only to solve some of the surface problems, in a short time the problem will certainly recur.

As we all know, precision parts processing is an essential step inside various closely related industries such as hardware industry, manufacturing industry, and electronics industry. There are many types of products involved in precision parts, which are mainly assigned according to the nature of the product. Generally speaking, precision parts also refer to the components and parts inside a piece of equipment, and by processing the parts in various ways they become better used and operated, and can also meet the needs of related industries and customers. To promote the development of this process, many industries are transforming their technologies to improve the quality and material of their parts.   Precision parts in the practical application is inevitably the higher the precision, the more exquisite can reflect the level of processing and quality, while these products are also popular with consumers, generally speaking in the processing of CNC machining has incomparable advantages and characteristics, the quality of its products are usually higher, so what are the characteristics of precision parts processing? First, first of all, precision parts processing is more efficient, precision parts processing can process multiple surfaces at the same time, compared to ordinary lathe processing can save a lot of processes, saving time, and the quality of the parts processed by CNC is also relatively stable compared to ordinary lathes.   Second, precision parts machining has an irreplaceable role in the development of new products, generally speaking, through the programming of parts of different degrees of complexity can be processed ah, and change and update the design only need to change the program of the lathe, which can greatly shorten the product development cycle.   Third, the degree of automation of precision parts processing is very sufficient, greatly reducing the physical labor intensity of workers, workers in the process of processing does not need to be like ordinary lathes that the entire control, mainly to observe and supervise the lathe. But the corresponding technical content of CNC machining is higher than that of ordinary lathe, so it requires higher mental labor compared with ordinary lathe. Fourth, the initial investment is relatively large compared to ordinary lathes, because the price of CNC lathes is very high, and its maintenance costs and the processing of the first preparation period is long.

Precision parts machining is one of the most common measures and means used inside the industrial stage. The first thing to consider in this area of technology is the quality and structure of the part itself. If poor quality parts are chosen, it will not help, no matter what way of processing methods are used. Therefore, the quality of the part in the machining of the part is a very important step. When it comes to parts, it is one of the essential products inside many mechanical devices. Parts are the basic elements that make up a machine. Machines generally include one or several transmission parts used to receive external energy (such as electric motors, internal combustion engines, steam engines). The implementation of the machine production function of the executive part (such as the machine tool in the tool), the original motion and power to the executive part of the transmission part (such as machine tools in the gear and screw drive mechanism), to ensure that the machine in the coordination of the work of the various parts of the detection and control system (such as machine tools in the CNC system) constitutes (that is, the machine by the original part, the transmission part, the executive part, the measurement and control part). The machine can be further disassembled to obtain various parts. Precision parts processing Parts are the basic elements of the machine, can be divided into two categories: one is in a variety of machines can be used in the parts (such as gears, shafts, etc.), known as common parts; the other is only in a certain type of machine parts (such as gun bolts, propellers, etc.), known as special parts; in addition to some of the synergistic work of the parts of the combination of parts called parts or components (such as couplings, reducers, etc.). reducer, etc.).

Due to market competition, under the new situation of "survival by quality", aluminum shell customization enterprises should not only strictly control service, but also pay attention to the quality of product samples and product shipments. Customized production of aluminum alloy shell is an extremely complex process. It is difficult to absolutely prohibit the production of unqualified products, so the inspection of products is very important. What role does quality inspection play in the production process? What are the functions of quality inspection? First, the control function: through the quality inspection of the incoming raw materials, the aluminum shell machining of the factory until the product shipment and other links, the flow of defective products is controlled layer by layer. Strictly implement various technical standards and inspection procedures, and strictly control the production of unqualified raw materials, the flow of unqualified semi-finished products into the next process, and the delivery of unqualified finished products. Aluminum housing Second, prevention function: through the first article inspection of aluminum alloy shell in each process, each team leader shall find out the quality problems caused by operation, clamping, processing procedures, drawings and other reasons as early as possible through daily patrol inspection, and take timely measures to reduce the occurrence of more nonconforming products. Third, supervision function: quality inspection is an indispensable technical supervision in the aluminum shell customization production process. Supervise those who violate the process flow and operation flow, transfer unqualified products to the next process without inspection, and supervise the warehousing balance of unqualified products. Aluminum alloy shell Fourth, feedback function. Quality inspection is the origin of aluminum shell information feedback. The inspector shall sort out, count, analyze and make judgments according to the quality and process conditions, and timely feed back the product quality information to the enterprise leaders and relevant departments. Provide timely and effective information basis for improving product design, process and operation methods.

Does the CNC machine tool for processing aluminum alloy shell of tensile parts need regular maintenance For the CNC processing of aluminum alloy shell of tensile parts, as long as the CNC processing equipment (CNC CNC machine tools) has a good reputation and reasonable price, CNC processing has a leading edge in the industrial market, but they often neglect the most important operation and maintenance of CNC machine tools. How to maintain CNC machine tools? The key to preventive maintenance of CNC machine tools is to strengthen daily maintenance. The main maintenance work includes daily inspection, weekly inspection, monthly inspection, quarterly inspection and semi annual inspection. The preventive maintenance of CNC machine tools is as follows: 1. Daily inspection of CNC machine tools Its main items include hydraulic system, spindle lubrication system, guide rail lubrication system, cooling system and pneumatic system. Daily inspection is based on the normal conditions of each system. For example, during the process inspection of the spindle lubrication system, the power light should be on, and the oil pressure pump should operate normally. If the power light is not on, the spindle should be stopped and the mechanical engineer should be contacted. Repair. 2. Weekly inspection of CNC machine tools Its main items include machine tool parts and spindle lubrication system, which should be checked correctly every week, especially the machine tool parts should be cleaned of iron filings and external debris. 3. Monthly inspection of CNC machine tools Mainly check the power supply and air dryer. Under normal conditions, the rated voltage of the power supply is 180V-220V, and the frequency is 50Hz. If there is any abnormality, measure and adjust it. The air dryer should be disassembled once a month, and then cleaned and assembled. 4. Quarterly inspection of CNC machine tools The quarterly inspection shall mainly be carried out from the machine tool bed, hydraulic system and spindle lubrication system. For example, when checking the machine tool body, it is mainly to see whether the accuracy and level of the machine tool meet the requirements in the manual. If there is any problem, contact the mechanical engineer immediately. When checking the hydraulic system and the spindle lubrication system, if there is any problem, replace 6oL and 20L of new oil respectively, and clean them. 5. Semi annual inspection of CNC machine tools After half a year, the hydraulic system, spindle lubrication system and X-axis of the machine tool should be checked. If there is any problem, the oil should be replaced and then cleaned. After being fully familiar with and mastering the knowledge of preventive maintenance, it is also necessary to have a deeper understanding of the causes and handling of abnormal phenomena in the oil pressure system. If the oil pump does not inject oil, the pressure is abnormal, and there is noise when machining the aluminum alloy housing, you should know what the main causes are and what the corresponding solutions are.

The principle of wireless aluminum filled alloy support sandblasting is to strike hard and small diamond sand particles on the surface of aluminum shell through sandblasting machine to form uniform small pits on the surface, making it look fine and even to the naked eye. The advantages of sand blasting process are not only this, but also: 1. Remove the oxide film on the surface of the wireless aluminum filled alloy shell. The naturally formed oxide film can be completely removed after sand blasting. This is also the reason why the sand blasting process is prior to the anodic oxidation process. 2. Prepare for other surface treatment processes. When the wireless aluminum filled alloy bracket after sand blasting is oxidized, the bonding force of the oxide film is stronger. 3. Improve the mechanical properties of aluminum parts. The aluminum parts after sand blasting can increase the smoothness by 0.5-1. There are also small depressions on the surface of the parts that can store lubricating oil. This makes the lubrication effect better, so as to extend the service life of aluminum parts and reduce the noise of mechanical operation. 4. After spraying, the tiny burrs on the surface of the aluminum alloy shell can be removed to obtain a smooth and clean surface.

The aluminum alloy shell profile die of the docking station plays an important role in the profile stretching production process, and is the basic tool to ensure the product molding and make it have the correct shape, size and accuracy. In the actual production process, the profile die has several adverse effects on the product surface effect: 1. Influence of aluminum alloy shell profile die with seam angle or poor welding The aluminum shell profile of the docking station adopts the plane shunt combined die stamping process, which has relatively deepened the difficulty in the profile production. The metal passes through the shunt and welding process, so there is a welding line for hollow profiles. There are two reasons for the gap: first, the shunt hole and welding chamber are narrow, the metal supply is insufficient, the metal does not form enough hydrostatic pressure in the welding chamber, and the product does not weld well and flows out of the mold hole, leading to the existence of welding gaps in the product; It is caused by poor welding of hollow profiles due to excessive lubrication and poor lubrication. 2. Reasons for the appearance of concave or convex arched surface on the wall of aluminum alloy shell profiles The reason for the concave arch surface of hollow aluminum alloy profile wall: the working belt of aluminum alloy profile die core is lower than the working belt of lower die hole, and the effective length of the working belt of die core is too short. The reason for the wall protrusion of hollow aluminum alloy profile: the mold has been used for a long time, the working belt of the mold core has been seriously worn, and grooves have appeared, which increases the friction resistance. The wall protrusion of hollow aluminum alloy profile is caused by the slow metal flow.

The aluminum alloy shell profile die of the docking station plays an important role in the profile stretching production process, and is the basic tool to ensure the product molding and make it have the correct shape, size and accuracy. In the actual production process, the profile die has several adverse effects on the product surface effect: Generation of stripes on the surface of aluminum alloy profiles Stripes appear on the outer surface of the profile, which is more obvious after anodizing. This defect is mainly found in the parts with large wall thickness difference of profiles, the welding parts of the metal under the splitter bridge, and the back side with "branches" on the inside and threaded holes. Cause: surface streaks caused by insufficient or excessive metal flow at the "branches" and threaded holes on the inner side of the profile; Stripes on the profile surface caused by the welding area under the die splitter bridge; There are problems in sectional drawing design of profiles. Due to the large wall thickness difference of profiles, the parts with sudden changes in the length of the working belt will have striped color difference after anodizing in Shenzhen. Because the cooling capacity of the machine is insufficient, the black speckle area after anodizing will be caused; The quality of the slab itself is poor, which affects the stripe color difference after anodizing. The way of unreasonable bending and twisting of aluminum shell profiles of the docking station: The working belt of the die core and the lower die hole is not matched properly, which causes uneven metal flow velocity at various parts of the profile; The size and position of the split hole of the symmetrical hollow profile die are processed asymmetrically, and the metal flow is uneven, which causes the uneven metal flow velocity; Diverter hole processing is irregular or there are obstacles on the die core to prevent metal flow. Correction method: Grind the outlet part of the mold core or shunt hole with an appropriate method, and appropriately expand these shunt holes to equalize the feeding if necessary; Remove obstacles by grinding.
