Precision stamping die processing program of main work parts

Precision stamping die main working parts namely convex and concave mold processing procedures, technical requirements of operation is not high, forming a more complex cavity. Switzerland and Japan and other countries in recent years, electric processing equipment carried on the thorough research and improvement, to create fully functional high precision NC and CNC wire cutting machine, machining precision can reach & plusmn; 0. 005-0. 001 mm, and even smaller. Machining surface roughness Ra value can reach 0. 4μm。 Stamping production of metal stamping die blanking dimension accuracy to + / - 0. 01, bending size + / - 0. 8 mm or less. By precision grinding method to produce precision stamping die, especially die manufacturing high accuracy, high life, such as: light small gap compound blanking die, multistage continuous composite die, etc. , has high dimensional precision, small work parts processing surface roughness Ra value, high die life etc. Stamping processing of die parts mainly adopts wire cutting or electric punch rough machining, the final precision grinding, also by forming and optical curve grinding, CNC nc machining, the machining accuracy can reach & plusmn; 0. 001-0. 0005 mm, the processing surface roughness Ra value can reach 0. 1 to 0. 025μm。 So, in the manufacture process of punching die, regardless of dimension precision, surface roughness of work parts, can satisfy the punching die, especially with the various demands of the compound die, die than electric processing manufacturing high a level.
