The heat treatment process of parts is to improve the performance and service life of GH3536 alloy. For different types of parts, different processes are used for heat treatment. These processes include solution treatment, stress relief treatment and size stabilization treatment, etc., what are they used for? The solution treatment can eliminate the residual stress and microstructure inhomogeneity in the alloy, make the alloy have better plasticity and toughness at high temperatures, and improve the machining performance of the alloy. Stress relief treatment can reduce the residual stress caused by machining and avoid cracks and deformation in the use of parts. The stable dimension treatment can further improve the microstructure of the alloy, increase the strength and hardness of the alloy, and prolong the service life The structure of GH3536 is mainly composed of austenite matrix, carbide and a small amount of Ti(CN) and TiN. The reasonable microstructure can ensure the alloy has good performance at high temperatures and improve the oxidation resistance and creep resistance of the alloy. Carbide can increase the hardness and strength of the alloy, but too much carbide will lead to the increase of brittleness of the alloy, and affect the toughness and plasticity of the alloy. Therefore, it is necessary to control the microstructure and carbide content of the alloy during heat treatment.

Tempering is a heat treatment process used to increase the toughness and ductility of materials such as steel. The tempering process involves heating a material to a temperature below its critical point, usually between 150°C and 700°C, and holding it at that temperature for a period of time before cooling it to room temperature. The purpose of tempering is to reduce the hardness and brittleness of a material that has been quenched or otherwise hardened. During tempering, some of the excess hardness is removed from the material, improving toughness, ductility and impact resistance. The temperature and duration of the tempering process can be adjusted to achieve the desired properties of the material. The higher the tempering temperature and the longer the duration, the softer the material and the better the ductility; the lower the tempering temperature and the shorter the duration, the harder and more brittle the material. The tempering process is commonly used in the production of steel products such as tools, gears and springs. It is also used in the production of structural components, such as bridges and buildings, to increase their toughness and fracture resistance.

There are many details that need to be paid attention to in the purchase and use of stainless steel. Try to choose the right one to ensure later use. And is stainless steel 304 food grade? Not necessarily food grade. General stainless steel 304 cannot meet the relevant requirements of food grade. If the surface of stainless steel 304 is marked with special symbols and words such as food grade, it belongs to food grade. After all, generally, stainless steel contains high levels of lead and manganese, while the content of these elements in food-grade stainless steel cannot exceed a certain standard. In addition, in order for 304 stainless steel to meet food-grade standards, the precipitation ratio of arsenic, cadmium, nickel, chromium, lead and other metal materials must be strictly controlled during the production process.

Titanium-containing gold precision processing technology Compared with traditional metal materials, titanium alloy materials have the characteristics of small thermal conductivity, low side properties, and high chemical activity. 9 The machining of titanium alloys includes tapping, turning, milling, drilling, and grinding. Cutting, etc., non-mechanical processing includes electrical processing technology, electrolytic processing technology, and corrosion processing technology. Titanium alloy precision corrosion processing characteristics and experimental methods The advantages of corrosion processing are that mechanical methods can be used to achieve the high hardness and high metal strength, the Dongguan ICT test fixture has complex shapes and thin-walled workpieces, no rigidity requirements for workpieces, and simple equipment, low cost, continuous and uninterrupted processing, and fast speed. The accuracy of corrosion processing is affected by both the deviation of the machining process and the gross deviation of the workpiece itself. Numerical simulation of precision machining of titanium and gold. The simulation of precision machining is usually studied from two aspects: two-dimensional simulation and three-dimensional simulation. The two-dimensional simulation improves and analyzes Jinli's processing and forming and processing tool parameters. The three-dimensional simulation of the vibration test fixture based on the two-dimensional simulation has higher requirements on the calculation ability of the software, and the time to achieve the result is longer and closer to the actual effect. The finite element method combines traditional processing methods and simulated processing methods, which is of great significance for improving production efficiency.

We will encounter various problems in processing and production. For example, when processing thin Feihu deformation parts, we must find out the weak links according to their different characteristics, and choose different process methods and clamping methods to fix them. Guaranteed processing requirements In many cases, we need to analyze the problem of variants in detail, and find practical ways to deal with the actual problems encountered. 1. Why do improperly machined parts cause deformation? In our actual production operation, if we use a three-jaw chuck to clamp a thin-walled outer circle, the clamping area will be too small and the clamping force will be unevenly distributed. After disassembly, the part clamped by the jaws may be due to Elastic deformation grows, eventually resulting in polygonal changes in the part. 2. Deviation in relative position adjustment, resulting in uneven sequence 3. Why should we emphasize the importance of part wall thickness difference 4. What kind of tool to choose is very important

There are many ways of polishing technology, and they are constantly updated and improved with the development of the times. With the era of informatization and intelligence, especially the increasing precision of instrument processing, which has reached the micron level recently, puts forward greater requirements for polishing technology. Traditional manual operations have been difficult to meet the requirements of precision machining. need. Therefore, the polishing process must be continuously developed and improved. The latest polishing machine tools are quite mature, which realize automatic processing of precision instruments, improve work efficiency and reduce manpower burden. The so-called polishing technology refers to the operation and treatment of the product surface by using certain equipment to reduce the surface roughness and make it smooth so that the next operation process can be completed. In addition to dealing with the roughness of the device surface, the polishing technology can also properly adjust the gloss of the device surface. Many products need to be operated to make the surface smoothness meet the requirements when surface treatment http://www.wau.cn/ achieves aesthetic or other purposes. At this time, the polishing process will play a role. We guide that the traditional surface treatment technology is mainly the first step of adding a covering layer or using scientific methods for surface treatment. The application of this technology is the premise of precision machining for surface treatment and reprocessing.

Under the premise of increasing work efficiency Improve the accuracy of surface treatment of precision instruments. However, the surface smoothness of some products is difficult for polishing machine tools. In order to better meet the requirements of precision machining surface treatment, grinding treatment technology came into being. This technology http://www.wau.cn/products-155088-0-0.html refers to the use of abrasive particles coated or pressed on the grinding tool, through the relative movement of the grinding tool and the workpiece under a certain pressure Finishing of machined surfaces. This grinding technique is very convenient and can be carried out by wet, dry and semi-dry grinding. This technology can be used in a wide range of applications, including technical materials, as well as non-metallic products, and the processing of surface shapes is more diverse, and it has become the main polishing technology of our time. In the actual polishing process, the appropriate grinding machine can be selected according to the properties and shape of the product, and the polishing agent can be added appropriately to ensure the polishing effect. All in all, polishing technology plays a very important role in precision machining. With the development of precision instruments, it continues to advance and innovate.
