 |
 |
| Cutting Conditions: V=330m/min : d=~1.5mm : f=0.3mm/rev : Wet : DNMG150408ZS |
| · |
CA4120 improved tool life by a factor of 1.5 times in comparison with Competitor K (K20 grade CVD). |
| · |
CA4120 showed better edge condition than competitor K and was ready for additional machining. |

| · |
Interrupted cutting at sprue and concave part. |
| · |
Competitor E's tool life was reduced due to chipping during interrupted cutting. |
| · |
KPD001 was stable without chipping and continued to machine 10,000 pcs / edge. |
