Precision parts processing is actually a kind of mechanical processing, but because of the high precision of parts processing, production machinery and process requirements are also relatively high. With the development of industrialization, the classification of precision machining is more and more, and the direction is more and more specialized.

Any machine is made up of many different small 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 precision, rough, fine machinery parts processing * separate. 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.

Heat treatment is usually arranged in the process of precision parts processing. The locations of heat treatment processes are arranged as follows: in order to improve the machinability of metal, such as annealing, normalizing and tempering, etc. generally are arranged before machining of mechanical parts.

The process of precision parts is very strict. Grasp the precision precision of the size, can reduce the loss of materials to reduce the cost. For example, the size of 1mm plus or minus how many microns, if the wrong size will become waste, parts can not be used.

Precision parts processing features

Precision parts machining mainly includes precision turning, mirror grinding and grinding. On the precision lathe, the single crystal diamond turning tool is used for micro turning. The cutting thickness is only about 1 micron. It is often used to process high-precision and highly polished parts such as spherical, aspherical and planar reflectors of non-ferrous materials. For example, the aspheric mirrors used to process nuclear fusion devices are 800mm in diameter, with maximum precision of 0.1 micron and external roughness of Rz0.05 micron.

2, precision parts processing precision parts machining accuracy in nanotechnology, even in the atomic units (atomic lattice distance is 0.1 ~ 0.2 nm) as the goal, the ultra precision parts machining method can not meet, need to use special precision parts processing methods, the application of chemical energy, electrochemistry energy, heat or electricity, etc., can make these energy beyond the joint between the atoms, so as to remove the workpiece appearance of adhesion between atoms, joint or lattice deformation, in order to achieve the purpose of the ultra precision machining.
