Tool life PCD vs. CVD

Before: PCD
Insert: DCGT 070204 PCD
Vc: 380m/min
f: 0,12mm/rev
time/hole: 6 sec
tool life: 7 days
After: CVD
Insert: DCGW 070204 N CVD
Vc: 510m/min
f: 0,16mm/rev
time/hole: 4 sec
tool life: 14 days

Benefits Carmex CVD against PCD

4 x higher tool life time
Much better surfaces
Much better tolerances
Turning process is much cheaper
Roughing and finishing possible
Boring smallest holes are possible
approx. 60-70% faster as grinding
Drilling carbide is possible
