1. Processing of precision hardware parts In order to better ensure the processing accuracy of machine parts, the processing of rough and fine mechanical parts is better carried out separately. Due to the large amount of drilling during the processing of rough mechanical parts, the cutting speed, clamping force and calorific value of the product workpiece are large, and the machining surface of its mechanical parts has a relatively obvious processing hardening condition, and the product workpiece has a very large internal surface. Large thermal stress, if the machining of rough and rough mechanical parts continues, the precision of the parts after finishing will be quickly lost due to the re-division of the pressure. Parts with high machining accuracy are specified for some mechanical parts. After roughing and before finishing, an ultra-low temperature quenching or solution treatment step should also be arranged to remove thermal stress.
2. The processing of precision hardware parts effectively adopts machinery and equipment. The machining of rough machine equipment parts is mainly to remove most of the machining capacity, and does not require high machining accuracy of mechanical parts. Therefore, rough machining should be carried out on equipment with relatively high output power and low precision, while the finishing process is It needs to be processed with a higher precision CNC lathe. Roughing and finishing are processed on different equipment, which can not only exert the working ability of the facility, but also increase the service life of the precision machine tool.
3. Precision hardware parts processing In the processing style of machine equipment parts, there is often a heat treatment process. The arrangement of the process parts of the heat treatment process is as follows: In order to improve the drilling processing characteristics of metal materials, such as quenching, quenching, heat treatment, etc., it is generally arranged before the machining of mechanical parts. In order to remove thermal stress, such as quenching and tempering treatment, quenching and tempering heat treatment, etc., it is generally arranged after roughing and before finishing. In order to better improve the physical properties of parts, such as nitriding, heat treatment, quenching, etc., it is generally arranged after the machining of mechanical parts. If there is great deformation after the heat treatment process, the final processing process must also be arranged.
