In the process of precision parts, heat treatment process is often arranged. The arrangement of heat treatment procedure is as follows: in order to improve the cutting performance of metal, such as annealing, normalizing, tempering, etc., it is generally arranged before the machining of mechanical parts.

Precision parts of the processing process is very strict, into the knife, knife out of the interlocking. The shape of the tool also has an impact: for example, the front Angle of the CNC machining tool, the edge round Angle and the amount of wear at the back of the tool have a great impact on the cold hardening layer.  The depth and hardness of the cold hardening layer increase with the decrease of the front Angle and the increase of the abrasion of the cutting edge and the back. Grasp the precision of the size, can reduce the loss of material to reduce the cost. Such as how many microns plus or minus 1mm, if the wrong size will become waste, parts cannot be used.

 Any machine is made up of many different little parts, each of which plays a crucial role. Parts need to be assembled, so the precision machinery parts processing manufacturer will according to the need of such reprocessing, a variety of different parts processing after we can get more suitable for their own parts, so in order to can make the products better service for yourself, so a lot of people are without precision machining is an important link.

In order to ensure precision parts processing accuracy, rough and fine machinery parts processing is best carried out separately. Because when coarse machinery parts processing, cutting quantity is big, the artifacts by cutting force, clamping force, heat, and mechanical parts processing surface has the obvious work hardening phenomenon, artifacts within the larger internal stress, if rough, coarse machinery parts processing for continuous, after finishing the parts precision will soon lost because of the stress redistribution. Cutting parameters of CNC machining: the change of cutting speed and feed has a great influence on cold hardening. When the cutting speed increases, the contact time between the tool and the workpiece is short, the degree of plastic deformation is small, and the hardening layer and hardness decrease. With the increase of feed velocity, the degree of plastic deformation and the degree of cold hardening increased.

Now there are more and more CNC manufacturing companies, the competition is fierce, the increase of parts also began to be more, and the application field is wide, also more and more require CNC precision parts processing requirements in precision, which is what Worthy pursue.
