The main steps of precision parts processing
Precision machinery parts processing look for Lifei Precision company, look for Lifei Precision company advanced equipment, experienced team, professional processing of all kinds of precision parts. Welcome to consult!

　　In order to better ensure the precision parts processing accuracy, coarse and fine mechanical parts production and processing are carried out separately. Due to coarse mechanical parts production and processing, large amount of drilling, by cutting speed, workpiece clamping force is big, calorific value, and its mechanical parts production and processing surface has the obvious work hardening condition, the internal stress of workpiece internal deposit is a big, if the coarse and fine mechanical parts production and processing continued, after deep processing precision of parts will rapidly due to stress again all over.

　　Heat treatment process is often encountered in the process line of precision parts. The distribution of heat treatment process parts is as follows: in order to improve the drilling production and processing characteristics of metal materials, such as quenching, quenching, heat treatment, etc., the general distribution is carried out after primary processing. Precision parts processing steps are very strict, under the knife, knife a ring buckle a ring. Grasp the precision of specifications, can reduce the consumption of raw materials to control the cost. For example, how many μm is the positive and negative pole of 1mm, if the specification is wrong, it will become waste, and parts can not be applied to the equipment.
　　Each device is made up of many different small parts, each of which plays a particularly important role. Parts must be assembled, so the provisions of precision parts processing manufacturers are relatively high, a variety of different parts processing after we can get more suitable parts of their own, so in order to better be able to make this product can better serve themselves, so precision parts processing this key step.
