NTK PVD carbide TMV Chipbreaker -POM plastic spool- TM4
NTK PVD carbide TMV Chipbreaker -POM plastic spool- TM4
-The existing tool had trouble with chip control when cutting plastic, leading to a 30% defect rate. Also, the existing tool chipped early during vibration cutting. Therefore, vibration cutting could not be used with the existing insert.
-TMV achieved stable machining with vibration cutting and reached 1.2 times longer tool life. Vibration cutting became possible, and short chips from TMV chipbreaker helped achieve 0% defect rate. Surface finish and dimensional accuracy also improved significantly.
Vibration conditions: LFV (MODE 1): D0.5, Q2.0, f0.03
