Precision machining

Process Introduction


Precision machining is the application of production processes including turning, milling, boring, drilling, EDM, engraving, grinding and other processes, through mechanical processing to remove the material on the workpiece, the production of drawings with strict dimensional accuracy and shape tolerance and high surface quality of precision parts process. Precision machining usually requires high-precision master machines and advanced process methods and CNC programming. Precision machined parts are usually provided to complete machine manufacturers and system integrators, and finished parts are used in a wide range of final market areas.
