 The importance of precision special mold parts processing surface quality.Precision mold parts business on the pros and cons of the quality of the surface abrasion of mold parts, the fracture resistance and the ability to resist with very close relationship, the direct impact is the service life of precision mold parts.In particular, the value of roughness of rough surface precision mold parts life had a great effect, and surface roughness value is too big, should be in work, in the psychological pressure, concentration, but the peak and valley prone to crack, impact effect on durability of punching die precision mold parts surface corrosion of heat resistance directly influence the service life of die and precision, therefore, the surface of precision mould parts processing pay attention to the following:
 (1) in the process of the mould parts processing to prevent emissions, but parts surface phenomenon, should strictly control the grinding process conditions and process methods.Such as grinding wheelhardness,particles, or parameters such as coolant, feeding;
 (2) in the process of machining precision mold parts work should stop in the surface of the mark.Interlayer crack, wound of all areas of impact.The existence of these defects will cause power concentration, be break the root of the cause early failure precision mould parts;
 (3) ground to fine grinding and polishing finishing and processing using the small surface roughness values, in order to improve the service life of precision mold parts.
 So you can improve the quality of mold parts processing.
