Standards for precision metal parts processing

date：2023/08/10

The standards of the precision hardware parts industry are very strict, and there are different processes such as cutting in and out 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 an increase in costs. At the same time, the parts are bound to be unusable, so there are many precision parts processing required. So 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 run separately, because the cutting amount, clamping force, heat generation, and cutting force of the workpiece are all Not the same, 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 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 mechanical parts.
(4) Generally speaking, almost all precision parts processing have heat treatment process, which can improve the cutting performance of metal.
