NTK PVD Carbide TMV Chipbreaker – Automotive Parts – 650
NTK PVD Carbide TMV Chipbreaker - Automotive Parts - 650
With the current tool, chips frequently wrapped around the part, resulting in repeated chip removal.
With the 650 grade, reducing spindle speed from 6600 RPM to 5000 RPM and increasing the depth of cut from 1.0 mm to 2.5 mm led to a noticeable improvement in chip control, and tool life was extended by 1.7 times.
These adjustments eliminated the chip removal issue and improved overall machining efficiency.
