Precision metal stamping die processing process key points

Precision metal stamping die main work parts that are convex, concave die processing procedures, the technical requirements on the operation is not high, can form a more complex cavity.

In recent years, Switzerland, Japan and other countries, the electrical processing equipment for in-depth research and major improvements, the manufacture of a full range of functions of high-precision NC and CNC wire cutting machine, the processing accuracy can be up to ± 0.005 ~ 0.001mm, or even smaller.The machining surface roughness Ra value can reach 0.4 m.

The precision metal stamping mould produced by hua-tech mould has the precise size of cutting to + / -0.002, and the bending size is within + / -0.08mm.

Precision metal stamping die is manufactured by precision grinding, especially high precision and high life stamping die, such as: thin material small gap composite blanking die, multi-station continuous composite die, etc., it has the characteristics of high dimensional precision, low working surface roughness Ra value and high die life.

Weihua mold processing mold parts mainly adopts edm wire cutting or rough machining by electric punch machine, and finally precision grinding, there are also forming grinding, optical curve grinding, CNC CNC machining, etc., the machining precision can reach ± 0.001 ~ 0.0005 mm, the machining surface roughness Ra value can reach 0.1 ~ 0.025 m.

Therefore, with the process of manufacturing the punch, regardless of the size of the precision, the surface roughness of the working parts, can meet the requirements of the punch, especially a variety of composite die requirements, than the electrical processing process of the punch manufacturing a higher grade.
