Punch for Rivet and Electric Contact

・Work material : Ultra fine Tungsten Carbide G5, G6
・Process machine, Micro Precision Process machine (No electrical discharge process).
・Mirror finish by Lap-less.
Bottom surface roughness :Ra0.05μm(same as lapping finish)

Difference to traditional process

1.Largely shorten a process time and 24 hours continuous process.

2.Achieved a big cost down

Running cost becomes 1/5～1/10 in comparison with traditional process.

3.Realized a quality improvement.

No micro crack nor hardened layer like electrical discharge.
Maximum potential of Tungsten carbide can be utilized.
