NTK TMV – Precision Machine Parts – ST4
NTK TMV - Precision Machine Parts - ST4
-Competitor's insert had short tool life with vibration cutting and could not make short chips.
-ST4 controls wear caused by high cutting edge temperature in stainless steel machining, achieving 6 times longer tool life.
-TMV chipbreaker produces short and stable chips with vibration cutting, resulting in zero chip trouble. In addition,
by increasing the feed rate by 1.5 times, it achieves higher productivity.
Vibration conditions: LFV (MODE 1): D0.5, Q0.7
