・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
