If the size is very different, the products will become scraps and need to be reworked to meet the requirements. This process is very time-consuming and laborious. Sometimes all the raw materials are scrapped and the cost increases. At the same time, the parts are bound to be unusable. There are many requirements for precision parts processing. So what are the requirements for precision parts processing?
- Generally, in order to ensure the machining accuracy of parts, the machining of rough parts and precision mechanical parts must be run separately. Because the cutting amount, clamping force, heat generation, and cutting force of the workpiece are all different. If rough machining and precision machining are performed continuously, the precision of precision machining parts will be lost due to the difference in stress.
- The rationality of equipment selection. The machining of rough parts does not require high machining accuracy, but mainly cuts the machining allowance, so precision machining requires very high-precision machine tools.
- In the process of precision parts, heat treatment processes are often arranged. The position of the heat treatment process is arranged as follows: in order to improve the cutting performance of the metal, such as annealing, normalizing, quenching and tempering, etc., it is generally arranged before the machining of the mechanical parts.
- Generally speaking, almost all precision parts are processed with heat treatment process, which can improve the cutting performance of metal.
