The polishing process is mainly used to reduce the surface roughness of the workpiece. When selecting a polishing process method for a metal workpiece, different methods can be selected according to different needs. The editor will share several common methods of the polishing process. 1. Mechanical polishing Mechanical polishing is a method of polishing to obtain a smooth surface by cutting and plastically deforming the surface of the material to remove the polished convex part. Generally, oil stone strips, wool wheels, sandpaper, etc. are used. Using auxiliary tools such as turntables, ultra-fine grinding and polishing methods can be used for high surface quality requirements.   2. Chemical polishing Chemical polishing is to make the microscopic convex part of the surface of the material dissolve preferentially compared with the concave part in the chemical medium, so as to obtain a smooth surface. The main advantage of this method is that it does not require complex equipment, can polish workpieces with complex shapes, and can polish many workpieces at the same time, with high efficiency. The core problem of chemical polishing is the preparation of polishing fluid. The surface roughness obtained by chemical polishing is generally several 10 μm.   3. Electropolishing The basic principle of electrolytic polishing is the same as that of chemical polishing, that is, to make the surface smooth by selectively dissolving the tiny protrusions on the surface of the material. Compared with chemical polishing, it can eliminate the influence of cathode reactions, and the effect is better.

The straight grain drawing process The straight wire drawing process is the most common metal wire drawing process. It is a process of machining straight lines on the surface of the aluminum plate by mechanical processing. Rotary wire drawing process The rotary pattern is also called optical rotation. This process is obtained by installing a cylindrical felt or abraded nylon wheel on a drilling machine, mixing polishing ointment with kerosene, and rotating and polishing the surface of an aluminum or aluminum alloy plate. texture. Spiral brushed is mostly used for the decorative processing of round signs and small decorative dials.   Random wire drawing process The chaotic wire drawing process is to make the aluminum plate move forward, backward, left, and right in all directions under the brushing of the high-speed running copper wire brush, and rub against the copper wire brush. This processing technology has a high impact on the surface of the aluminum or aluminum alloy plate. Require.

The ability of quenched steel to resist the decrease in hardness during tempering is called tempering stability. Since the alloy element can hinder or delay the transformation of the quenched steel during tempering, it can delay the decomposition of martensite and the transformation of retained austenite, increase the recrystallization temperature of ferrite, and make it difficult for carbides to aggregate Grow up while maintaining a large degree of dispersion. Therefore, the tempering stability of alloy steel is better than that of carbon steel. A higher tempering temperature can be used for steel with higher tempering stability, the quenching stress can be eliminated more thoroughly, and the comprehensive mechanical properties after tempering can also be better.

Bearing function In terms of its function, it should be supported, that is, it is used to support the shaft literally, but this is only part of its function. The essence of support is to be able to bear radial loads. It can also be understood that it is used to fix the shaft. Bearing quick and easy automatic selection is included. It is to fix the shaft so that it can only achieve rotation while controlling its axial and radial movement. A motor won't work at all without bearings. Because the shaft may move in any direction, and the motor is required to only rotate when it is working. Theoretically speaking, it is impossible to achieve the function of transmission. Not only that, but the bearing will also affect the transmission. In order to reduce this influence, good lubrication must be achieved on the bearing of the high-speed shaft. Some bearings themselves have been lubricated, called pre-lubricated bearings, and most of the bearings must have lubricating oil. When running at high speed, the friction will not only increase the energy consumption but what is more terrible is that the bearings are easily damaged. It is one-sided to say that sliding friction is converted into rolling friction because there is something called a sliding bearing. lubricating The purpose of lubricating rolling bearings is to reduce the internal friction and wear of the bearing, prevent burning and sticking; prolong its service life; discharge frictional heat, cool down, prevent the bearing from overheating, and prevent the lubricating oil itself from aging; it also prevents foreign matter from invading the inside of the bearing or prevents rust and corrosion The effect. Lubrication method The lubrication methods of bearings are divided into grease lubrication and oil lubrication. In order to make the bearing function well, it is necessary to select a lubrication method suitable for the conditions of use and the purpose of use. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication has the advantage of simplifying the structure around the bearing. The advantages and disadvantages of grease lubrication and oil lubrication are compared. When lubricating, special attention should be paid to the amount used. Whether it is oil lubrication or grease lubrication, too little amount of lubrication will not fully affect the life of the bearing, and too much amount will produce large resistance and affect the speed. Seal Bearing seals can be divided into two types: built-in seals and external seals. The so-called self-sealing of the bearing is to manufacture the bearing itself as a device with sealing performance. Such as bearings with dust covers, sealing rings and so on. This kind of sealing takes up little space, is easy to install and disassemble, and is relatively low in cost. The so-called bearing plus sealing performance device is a sealing device with various performances manufactured inside the mounting end cover and the like. Bearing seals are divided into two types: non-contact seals and contact seals. Non-contact seals are suitable for high-speed and high-temperature occasions and have different structural forms such as gap type, labyrinth type and gasket type. The contact seal is perfect for medium as well as low-speed working conditions. There are commonly utilized structural kinds, such as really felt seals and leather bowl seals. According to the working conditions of the bearing and the requirements of the working environment on the degree of sealing, various sealing forms are often used comprehensively in engineering design to achieve a good sealing effect. The selection of external seals for bearings should consider the following main factors: 1. Bearing lubricant and type (grease and oil); 2. The working environment of the bearing and the size of the occupied space; 3. Advantages of the shaft support structure, allowing angular deviation; 4. The peripheral speed of the sealing surface; 5. The working temperature of the bearing; 6. Manufacturing cost.

1. Implement scientific CNC processing management CNC processing machine tools are very different from ordinary machine tools. Therefore, conventional management methods cannot be used in CNC processing machine tools. After years of practice, it has been shown that the management method of CNC machine tools is "specialized management and cluster use". Process technology preparation can be carried out by the process technology department of the factory, and the production tasks can be issued uniformly. Enterprises with better production conditions can use computer-integrated management systems to manage the production mode. By reducing the production preparation time and optimizing the logistics route, etc., the statistics and planning of effective information are realized, and the purpose of improving production is achieved. 2. Reasonable selection of cutting tools The blade is an important part of the cutting process, especially in ensuring the processing quality and improving the processing efficiency. While CNC machine tools are developing in the direction of high speed, high rigidity and high power, they also put forward higher requirements for tool performance. In order to adapt to the development trend of CNC machine tools, cutting tools are also developing in the direction of stability and high performance. Therefore, when selecting tool materials, it is generally necessary to choose carbide tools according to the processing conditions. If conditions permit, you can also choose to use coated tools with better wear resistance and more stable performance, cubic nitride tools and ceramic tools. 3. The application of the tool holder The choice of the tool holder directly affects the installation and measurement time of the workpiece, and also has a certain impact on the machining error of the workpiece. Therefore, when selecting and applying workpiece fixtures, the following aspects need to be paid attention to:Improving the assembly of combined fixtures and vacuum fixtures can effectively shorten the auxiliary time. (2) Further unify the positioning datum and reduce the workload and the number of fixtures in the positioning process. The use of constant force fixtures can effectively deform the workpiece, which is of great help to improve machining accuracy. (4) Fixtures can also use a computer-aided management system. Nanzhao gear, Tanghe gear, Xixia gear, Zhenping gear, Neixiang gear, Sheqi gear, Fangcheng gear, Dengzhou gear, etc., Nanyang gear, Nanzhao gear. Fourth, the establishment of processing procedures should be reasonable The use level of CNC machine tools has increased the technical requirements for equipment operators. Not only must they understand the technical content, but they also need to have a certain understanding of programming skills and mechanical processing technology. Under the premise of ensuring the processing quality, it is a good process route to reduce the number of program segments as much as possible and shorten the processing cycle of the workpiece. For plant operators, this is a challenge. 5. Machine tool maintenance Due to the high cost of CNC machine tools, the maintenance of CNC machine tools helps to extend the service life of equipment and reduce costs to a certain extent. Mechanical maintenance protection mainly includes three aspects: (1) Preventive maintenance: This maintenance ensures the normal operation of the machine tool. (2) Fault maintenance: When the machine tool fails, troubleshoot and eliminate the fault. (3) Restore the normal operation of the equipment: transform the old CNC machine to improve the efficiency of the equipment. 6. Innovation process method The process method is constantly developing with the progress of science and technology. At present, the process methods adopted by general companies cannot effectively improve the processing efficiency of CNC machine tools. Therefore, enterprises should strengthen the innovative training of CNC machine tools, innovate in process technology, and improve the processing efficiency of CNC machine tools.

The processing types of mechanical processing can be divided into single-piece processing, batch processing, and mass processing. Single-piece processing: processing a certain mechanical part alone, almost no repeated processing. Batch processing: Batch processing and manufacturing of the same mechanical parts. Mass processing: When the product quantity is large, it is necessary to repeat the processing of a precision mechanical part. The use of drag chains for mechanical accessories is also inseparable from the machining process. The drag chains can protect cables, oil pipes, and air pipes from damage and maintain precision during machining.
