What are the requirements for precision parts processing

The standards of the precision parts processing industry are very strict, and there are different processes such as inserting and exiting the knife during processing.

The size will also have different specific requirements according to the product, and the processing accuracy requirements will also be different. Generally speaking, the precision processing accuracy requirements are very high, sometimes even accurate to the micron difference under 1mm. If the size is very different, the product It will become a waste product and need to be reworked to meet the requirements. This process is very time-consuming and laborious. Sometimes all the raw materials are scrapped, resulting in increased costs. At the same time, the parts are bound to be unusable. Therefore, there are many precision parts processing. required. So what are the requirements for precision parts processing? The following is the answer of Mr. Xu Xiaogang, general manager of Ruisheng Technology:


(1) Generally, 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 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.


(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 tools.


(3) In the processing route of precision parts, heat treatment processes are often arranged. The location 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.


(3) Generally speaking, almost all precision parts are processed with heat treatment process, which can improve the cutting performance of metal.
