High Precision Parts

Machining of high-precision parts is a process of removing materials from the workpiece through machining, and manufacturing precision parts with high requirements for precision and surface quality. The production process includes turning, milling, drilling, gear shaping, honing, grinding and other technological processes.

Precision machining is the process of removing material from the workpiece through machining to produce precision parts with strict tolerances and high surface quality. Precision machining usually requires computer numerical control CNC programming to convert specific designs into precise shapes from multiple dimensions. Precision machined parts are usually provided to machine manufacturers and system integrators, and finished parts are used in a wide range of end markets.

Precision machining is achieved by using precision machine tools, precision measuring tools and measuring instruments under strictly controlled environmental conditions. Machining accuracy of 0.1 microns or more is called ultra-precision machining.

The technological effects of precision machining are:

① The geometric shape and mutual position accuracy of the parts reach the micron or arc second level;

② The limit or feature size tolerance of the part is below micron;

③ The microscopic unevenness of the surface of the part (the average height difference of the surface unevenness) is less than 0.1 micron;

④ Mutual accessories can meet the requirements of coordination ability;

⑤ Some parts can also meet the requirements of precise mechanics or other physical characteristics
