The general principles of precision mechanical parts machining

2021/09/29



Precision mechanical parts processing technology, directly affects the development of a country's cutting-edge technology and defense industry, so countries around the world attach great importance to this, put a lot of power into research and development, then, the general principles of precision mechanical parts processing is what?
 
Precision mechanical parts processing general principles
 
1, the choice of equipment to be reasonable. Rough machining of mechanical parts is mainly cut off most of the machining margin, do not need high precision machining of mechanical parts, so rough machining should be greater power and high precision machine tools, to complete the process adhere to the use of a relatively high precision machine. Rough and fine machining on different machines, can give full play to the equipment capacity, can extend its life precision machine tools.
 
2, coarse and fine mechanical parts processing to be separated to better ensure precision parts processing accuracy. Because when coarse mechanical parts machining, cutting volume, the workpiece cutting force, clamping force, heat, mechanical parts machining surface has obvious machining hardening phenomenon, the workpiece in the larger internal stress, if rough, rough mechanical parts machining is completed continuously, the accuracy of the parts will soon lose due to stress redistribution. For some high precision parts of mechanical parts processing. After roughing and finishing, should also be arranged or aging treatment low-temperature annealing process to eliminate internal stresses.
 
3, in the high precision mechanical parts processing process route, pay attention to the need to arrange heat treatment process. Location arrangements are as follows: heat treatment process to improve the cutting properties of the metal, such as annealing, normalizing, tempering, general arrangements in the machining of mechanical parts. Internal stress relief, such as aging treatment, conditioning treatment, such as the general layout, after rough machining, but in the completion. In order to improve the mechanical properties of the parts, such as carburizing quenching and tempering, generally arranged in the machining of mechanical parts. If the deformation is large after heat treatment, but also to arrange the final machining process.
