Punch for silver bimetal rivet Contacts

・Work Material：Fine-gained WC-Co, G5, G6 etc.
・Processing Machine：Precision Micromachining Center
（Not shaping by the sinker electrical discharge machining )
・Mirror finish with Lap-less
Roughness of the bottom：Ra 0.020μm（same as lapped finish）

【Difference from Existing Processing】

1.Reduce its processing time substantially and 24h in a row

[Processing time per piece] Existing Process：Sinker electrical discharge machining + Turn out the electrode + lapping = 50 minutes
New Process　：Direct carving                                                                                        =15 minutes
*Available mass-production of greater than 1,000 units

Series processing of 30 units per a lot

2.Ensured Substantial Cost-cutting

Its running cost would be 1/5 to 1/10 of the existing process

3.Delivered its quality improvement

No hardening layer nor micro-crack as the electrical discharge machining
Maximize its potential of the WC-Co
