What Are the Requirements for Precision Parts Processing?

The standard of precision parts processing industry is very strict. There are different processes such as feeding and discharging. The size will also be different according to the specific requirements of the products, and the requirements of the processing accuracy will be different. Generally speaking, the requirements of precision machining accuracy are very high, sometimes even to the number of micrometers under 1 mm. If the size difference is very big, the product will become waste and need to be reworked to meet the requirements. This process is very time-consuming and laborious, and sometimes it will make all the raw materials Material scrap, resulting in an increase in costs, at the same time, parts are bound to be unusable, so precision parts processing is a lot of requirements. What are the requirements for precision parts processing? 

(1) Generally, in order to ensure the machining accuracy of parts, the machining of rough parts and precision mechanical parts must be operated separately, because the cutting amount, clamping force, calorific value and cutting force of workpiece are different between rough machining and precision machining. If rough machining and precision machining are carried out continuously, the precision of precision machining parts will be lost due to different stresses.

(2) Rationality of equipment selection. The requirement of machining precision for rough parts is not high, but mainly for machining allowance cutting, so precision machining requires machining in very high precision machine tools.

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

(4) Generally speaking, almost all precision parts have heat treatment process, which can improve the metal cutting performance.
