The leading Cermet series for next generation

Transcription

1 Optimal grade for high precision machining High Chipping Resistance High Wear Resistance Excellent Surface Finish The leading Cermet series for next generation High wear resistance even in high speed machining Equalized substrate improves chipping resistance. Application of the grade to an optimal edge increases surface roughness.

2 We Create Your Tomorrow! The leading Cermet series for next generation High wear resistance + High chipping resistance + Excellent surface finish Features High wear resistance in high speed machining over vc 250m/min. Equalized substrate, TiCN prevents chipping on the upper side of the insert.
