Pay attention to how machining precision hardware components

Precision parts processing requirements

In complex precision parts, the processing is very strict, and the processing procedures include notches, notches, etc. There are specific requirements for size and accuracy. For example, if the size of 1mm plus or minus several microns is wrong, it may become a waste product. This is equivalent to reprocessing is very laborious, and sometimes it becomes waste. This has caused an increase in cost, and at the same time, the parts are definitely unusable.

1) In order to ensure the precision of precision machining, the processing of coarse and fine mechanical parts should be carried out separately. Due to a large amount of drilling when rough machining parts, the steel parts are subjected to high cutting speed, clamping force, high heating value, and the surface layer of the machined parts has obvious cold work hardening conditions, and there is great internal stress inside the workpiece. If rough and rough mechanical parts are processed continuously, the accuracy of the finished parts will be quickly lost due to the redistribution of stress.

2) Reasonable choice of equipment. The rough machining of mechanical parts is mainly to cut off most of the machining allowance and does not require high machining accuracy. Therefore, rough machining should be performed on a high-power, low-precision machine tool. The finishing process requires high-precision machine tools.

3) Arrange the heat treatment process in the precision parts processing process. In order to improve the cutting performance of metals, annealing, normalizing, and tempering of the heat treatment process are generally carried out before the machining of mechanical parts.
