Dalian precision parts processing technology (heat treatment process), to determine the machine tool, clamping method, measurement method, machining allowance, cutting amount and man hour quota used in each process. Fill all contents in the process procedure table, which is the machining process procedure. There are strict requirements. Only the positive and negative errors within the specified requirements are qualified parts, otherwise they are unqualified parts. For example, if the diameter of an embedded cylinder is too large and exceeds the allowable range of error, it will cause failure to insert. If the actual diameter is too small and exceeds the lower limit of the allowable negative value of error, it will cause too loose and unstable insertion. Non standard precision parts processing equipment and testing equipment. Advanced processing equipment makes it easier to process precision parts with higher precision and better effect. One of the main characteristics of the development of auto parts is that system development and module customization are currently being implemented. This can largely meet the needs of mass development and is a strategic choice for many auto parts industries. Through system development and modular manufacturing, we can follow the trend of industry development and stay at the forefront of industry development. With more and more types of auto parts, there are more and more auto brands and types. Therefore, when processing auto parts, the transfer speed is relatively fast to meet international and domestic needs. Because most auto parts are made of metal. If the environment is wet when it is stored, it is easy to show signs of corrosion. Therefore, in order to select better quality auto parts, you must check their surfaces for signs of corrosion. Only such products can be used with more confidence.

CNC processing procedure design and preparation of special documents for CNC processing are suitable for CNC processing: 1. The contents that cannot be processed by general machine tools should be taken as the priority; 2. The general machine tools are difficult to process, and the production efficieCNCy is high in the case of multiple varieties and small batch production, which can reduce the time for production preparation, machine tool adjustment and process inspection, and the cutting time is reduced due to the use of cutting amount. The coCNCept and content of CNC processing technology and its important role in CNC processing should be clarified, and the current CNC processing technology and processing technology should be comprehensively understood. The CCNC system can control the machine tool to automatically select and replace tools according to different procedures, automatically set tools, and automatically change the spindle speed and feed rate. It can continuously complete drilling, boring, milling, reaming, tapping and other processes. Therefore, it greatly reduces the time of auxiliary processes such as workpiece clamping, measurement and machine tool adjustment, and has good economic effect for parts with complex machining shape, high precision requirements and frequent variety replacement.

Sucker materials processed by Shenzhen machinery are made of nitrile rubber, which has a large breaking force. Therefore, they are widely used in various vacuum holding equipment, such as construction, paper industry, printing, glass and other industries, to achieve the task of holding and transporting thin and light articles such as glass and paper. The price of vacuum cups is about 1000 yuan or 2000 yuan each, while the expensive ones are thousands of yuan. The basic time is mainly used to change the size, shape and surface quality of the workpiece, including the time for tool approaching, cutting in, cutting and cutting out. It is expressed by the percentage of operation time according to the complexity of processing Preparation end time: This time refers to the time consumed to complete the preparation and completion of a batch of processing workpieces, including drawing familiarity, understanding of process documents, conversion of dimensions, borrowing and returning tools, installation of cutter bars, etc. When the mechanic finishes, he/she should clean the machine tool in time and send the finished products.

Shenzhen machining vacuum sucker needs to consider many factors, such as brand, connection mode, material and material. For example, the suction cup is made of nitrile rubber. Basic introduction: vacuum sucker is one of the actuators of vacuum equipment. The sucker material is made of nitrile rubber, which has a large breaking force. Therefore, it is widely used in various vacuum holding equipment, such as construction, paper industry, printing, glass and other industries, to achieve the task of holding and transporting thin and light articles such as glass and paper. In the production process, the process of directly changing the shape, size, relative position and nature of production objects to make them into finished or semi-finished products is called process. The technological process is the main part of the production process. The process of making it into finished or semi-finished products is called technological process. It is an important part of the production process. The technological process can also be divided into casting, forging, stamping, welding, machining, assembly and other technological processes. The mechanical manufacturing technological process generally refers to the sum of the machining technological process of parts and the assembly technological process of machines. Other processes are called auxiliary processes, such as transportation, storage, power supply, equipment maintenance, etc. The technological process is composed of one or several sequential processes. One process is composed of several work steps, and one work step is composed of several tool passes. They are divided into three stages: rough machining, semi finish machining and finish machining. Mainly to ensure the processing quality; It is conducive to the rational use of equipment; It is convenient to arrange the heat treatment process; It is convenient to find blank defects.

The purpose of analyzing part drawings and process requirements in Shenzhen CNC machining is to determine processing methods, formulate processing plans, and identify problems related to production organization. After the above two steps are completed, the processing program can be compiled according to the determined processing scheme (or plan) and the data obtained by numerical calculation and the program format and code format required by the CNC system. In addition to understanding the functions of the CNC machine tools and systems used, programmers should be familiar with the program. The control medium is mostly perforated tape, or it can be tape, disk and other information carriers. With the use of perforated tape readers or tape drives, disk drives and other input (output) devices, the program information on the control medium can be input into the CNC system program memory. Calculate the part contour data according to the geometric dimensions of the part drawing, or calculate the tool center (or tool tip) running track data according to the part drawing and tool path. The purpose of numerical calculation is to obtain all relevant position coordinate data required for programming. Programmers should not only understand the functions of the CNC machine tools and systems used and be familiar with the program instructions, but also have the process knowledge related to mechanical processing, so as to prepare correct and practical processing programs. The control medium is mostly perforated tape, which can also be information carriers such as magnetic tape and magnetic disk. The program information on the control medium can be input into the CNC system program memory by using the perforated tape reader or tape drive, disk drive and other input (output) devices.

In the fields of modern microelectronics, information, optics and other fields, precision grinding and polishing of Shenzhen precision parts are very important in order to realize the functions of functional ceramics and crystal materials. For example, semiconductor integrated circuit silicon substrate, ferrite magnetic sheet, gem infrared window, piezoelectric crystal oscillator substrate. In the operation process, the requirements for workers' skills are reduced, and the quality of the processed workpiece is stable and the processing efficiency is high. Automatic processing eliminates a large number of errors in worker operations, and improves product consistency and productivity. CNC machining of precision parts is different from that of ordinary machine tools. Control information required for NC machining, such as tool path, sequence of various actions, and various auxiliary functions (such as spindle speed, feed speed, tool change, coolant switch) are stored in the control medium in digital form. And the machine tool is an automatic processing process realized by a numerical control device. Providing equipment and means for various sectors of the national economy has unlimited economic and social impact. Europe, the United States, Japan and other industrialized countries have completed the industrialization process of CNC machine tools, while China started in the 1980s and is still in the development stage.   According to its structural characteristics, the machined parts can be divided into internal shape, shape, curved surface or plane and other parts. Generally, the plane and locating surface are machined first, and then the hole is machined; Then machine the hole. First deal with simple geometric shapes, then deal with complex geometric shapes; First, machine the parts with low accuracy, and then machine the parts with high accuracy requirements. The point of the compound machining machine tool is that it can greatly shorten the production cycle of the workpiece and improve the machining accuracy of the workpiece. In addition, it can realize completely different machining processes on the compound machine tool. Compound machining is an important technical development direction of CNC machine tools.

Due to the accelerated upgrading cycle of the new products processed by Shenzhen CNC, the processing parts of the mold, aviation, military and other industries are not only complex but also have increased varieties. The development from precision machining to ultra precision machining (ultra-high precision machining) is the direction that the world's industrial powers are committed to. Its precision ranges from micrometer to submicron and even nanometer (

In terms of improving precision and productivity, mechanical manufacturing technology has been developed rapidly, while in terms of improving productivity, improving automation is the direction of efforts of all countries. In recent years, the machining of precision parts has developed rapidly from numerical control to CIMS, and has been used in a certain range. The transformation from finish machining to super finish machining is also the development direction of major developed countries in the world. Precision machining can be divided into four categories: tool cutting, abrasive machining, special machining and composite machining. With the development of machining technology, many new machining mechanisms have emerged. Therefore, the machining of precision parts, especially the micro machining of precision parts, must be carried out according to the forming mechanism and characteristics of parts. There are three kinds of machining: cutting, combined machining and deformation machining. Cutting, also known as separate machining, refers to a processing method that uses force, heat, electricity, light and other processing methods to separate some materials from the workpiece. The combination processing is to use physical and chemical methods to bond and weld the workpiece surface to form a layer of surfacing of different materials, such as electroplating, gas phase surfacing, oxidation, carburization, bonding, welding, etc; Deformation processing is to use force, heat, molecular motion, etc. to deform the workpiece and change its size, shape and function, such as casting, forging, etc. The concept of visual machining has broken through the traditional means of de machining. It has the characteristics of accumulation, growth, deformation, etc. It also emphasizes surface processing and forms surface processing skills. Compared with chip free cutting, the cutting of precision parts has the following advantages: First, the cutting process has both a higher cutting rate and better economic effects, such as compared with laser plasma processing. The reason is that only by supplying a large amount of energy can we achieve a high material cutting rate. On the other hand, there are still problems whether the machined workpiece can meet the requirements of size and shape accuracy. In the mass production process, the chip free pressure machining is mainly used, and the final qualified workpiece shape can be obtained only by subsequent cutting. Therefore, the step of machining is to make the workpiece reach a higher precision. The machining of precision parts, especially in the trend of small batch production, requires higher and higher precision of workpiece shape and dimension, opening up a wider new field of precision parts processing. The use of lathe naturally requires various turning processes, but it should also be noted that drilling, milling, grinding and gear cutting can be completed on one lathe (process integration). This machining method is applicable to the modular machine tool of the turning and milling machining center being developed at present.

The division of precision parts processing stages should not be compared, but should be flexibly controlled according to the quality requirements, structural characteristics and production guidelines of parts. 1. To ensure the processing quality. When the workpiece is rough machined, the removed metal layer is thicker, the cutting force and clamping force are larger, and the cutting temperature is higher, which will cause greater deformation. If the processing stages are not divided, and the rough machining and finish machining are mixed together, the processing errors caused by the above reasons cannot be avoided. According to the processing stage, the processing error caused by rough machining can be corrected by semi finishing and finishing, so as to ensure the processing quality of parts. 2. Use the equipment reasonably. The rough machining allowance is large, the cutting amount is large, and the machine tools with large power, good rigidity, high efficiency but low accuracy can be used. The precision machining has small cutting force and little damage to the machine tool. Use high-precision machine tools. This gives full play to the respective characteristics of the equipment, which can not only improve the processing productivity of Dalian precision parts, but also extend the service life of precision equipment. 3. It is convenient to find blank defects in time. Various defects of the blank, such as porosity, sand inclusion and insufficient allowance of the casting, can be found after rough machining to facilitate timely repair or scrapping, so as to avoid further processing and waste. 4. It is convenient to arrange the heat treatment process. For example, after rough machining, stress relief heat treatment is generally arranged to eliminate internal stress. Final heat treatment such as quenching shall be arranged before finishing, and its deformation can be eliminated by finishing. When the processing quality of precision parts is not high, the rigidity of the workpiece is good, the precision of the blank is high, the machining allowance is small, and the production process is not large, so there is no need to divide the processing stages. For heavy workpieces with good stiffness, because clamping and transportation are time-consuming, all rough machining and finishing are usually completed in one clamping.
