The surface treatment process of precision mechanical parts processing In precision mechanical parts processing, the requirements for strength and toughness are relatively high. Its working performance and service life are closely related to its surface performance, and the improvement of surface performance cannot be solely dependent on It is also very uneconomical to do it with materials, but in actual processing, its performance must be up to standard. At this time, surface treatment technology is needed. Mold polishing technology is a very important link in the field of mold surface treatment, and it is also an important process in the process of workpiece processing. The surface treatment process of precision mechanical parts processing is very important in the processing process.
It is worth reminding that the mold surface polishing of precision parts is not only affected by the process and polishing equipment, but also by The influence of the mirror finish of the part material is not paid enough attention in the current processing, which also shows that the polishing itself is affected by the material. Although the processing technology to improve the surface performance of precision parts is constantly innovated and upgraded, the more commonly used in the processing of precision parts are mainly hardened film deposition, nitriding and carburizing technologies. Because the nitriding technology can obtain a very high level of surface performance, and the process of the nitriding technology has a very high consistency with the quenching process of precision parts. The temperature of nitriding is very low, so after the nitriding technology, there is no need for intense cooling process, so the deformation of precision parts will be very small. Precautions for the installation and debugging of mechanical parts of CNC machine tools in Anhui Standard Processing Factory.

Precautions for safety in CNC lathe processing. Parts refer to single parts in the machine that cannot be separated. They are the basic components of the machine and the basic unit in the machine manufacturing process. The manufacturing process generally does not require an assembly process. Such as sleeves, bushes, nuts, crankshafts, blades, gears, cams, connecting rod bodies, connecting rod heads, etc. Non-standard parts simply means that there are no certain standard parts. Making custom parts is easier than making standard parts. It will not be so complicated. Everyone knows that improper operations in CNC lathe processing will cause certain damage to the operator, so we must strictly abide by the operating rules to ensure safety when using CNC lathes for non-standard parts processing. Specific precautions for CNC lathe processing safety As follows: 1. First of all, before processing non-standard parts, you must do the preparatory work, carefully check whether your clothes meet the requirements of the work, and must strictly abide by it. 2. Check whether the equipment meets the normal working standards, whether the voltage of the CNC lathe is stable, the socket must be a triangular socket and the circuit must have a ground wire. Before the formal operation, a dry running test is required for the CNC lathe. It can be powered on under abnormal conditions. 3. If an abnormality occurs during the operation of the CNC lathe, the inspection and troubleshooting must be performed after the machine has completely stopped working.
The division of labor and quality requirements for large-scale machining are clear. Before working, large-scale machining should wear protective equipment. Gloves and scarves must not be worn. Before starting the machine tool, you must understand the purpose and operation method of each handle, and check whether each part of the machine tool is running normally. Before starting the machine tool, a wrench must be used to clamp the workpiece. Large-scale machining is not allowed to start the machine without the permission of the knowledgeable personnel. Before the machine is started, it is not allowed to work such as speed change, chip cleaning or measurement, and it is not allowed to touch the running part. If there is foreign body or chip on the machine, it is not allowed to go by hand. Take or blow with your mouth. When large-scale machining is working, if you find that the object is loose or the equipment is abnormal, you need to stop it immediately. After the operation, you should clean up the tools and clean the working site of the machine tool. Do not put the workpiece, workpiece and other objects on the machine table . In large-scale machining, it is not allowed to touch the workpiece and other moving parts by hand during the work, and it is not allowed to lean on the machine to avoid causing other problems. When two people operate a machine at the same time, they must have a clear division of labor and close cooperation. Control the quality of raw materials: High-quality raw materials are the prerequisite for the production of high-quality products. Our company uses 40Cr and 45 steel to make gears. Regardless of the way, the raw materials must undergo strict chemical composition inspection, grain size determination, and purity evaluation after they arrive at the factory. The purpose is to adjust the heat treatment deformation in time to improve the quality of the tooth profile processing. More than 30% of gear transmission noise is caused by burrs and bumps. Some factories remove burrs and bumps before the gearbox is assembled. Basic introduction and technical requirements of large-scale machining.
