The standards of the precision parts processing industry are very strict, and there are different processes such as feeding and feeding during processing. The size will also have different specific requirements according to the product, and the requirements of machining accuracy will also be different. Generally speaking, the requirements of precision machining accuracy are very high, sometimes even accurate to the difference of how many microns under 1mm, if the size of the product is very different It will become waste and need to be reworked to meet the requirements. This process is very time-consuming and labor-intensive. Sometimes all raw materials will be scrapped, resulting in increased costs. At the same time, the parts must be unusable. Therefore, there are many precision parts processing. required. So what are the requirements for precision parts processing?

(1) Usually, in order to ensure the machining accuracy of the 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 in the machining of rough parts and precision parts are all Differently, if roughing and precision machining are carried out continuously, the precision of precision machined parts will be lost due to the difference in stress.

(2) 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 tool machining.

(3) In the processing route of precision parts, a heat treatment process is often arranged. The location of the heat treatment process is arranged as follows: in order to improve the machining performance of the metal, such as annealing, normalizing, quenching and tempering, etc., it is generally arranged before the machining of mechanical parts.

(3) Generally speaking, the processing of precision parts almost has a heat treatment process, and the heat treatment process can improve the cutting performance of the metal.
