NTK PVD Carbide – Bolt – 650
NTK PVD Carbide - Bolt - 650
-The competitor’s tool had issues with short tool life and unstable dimensions during deep cutting (D.O.C. = 4.5 mm). Due to the tight tolerance requirement (less than 0.01 mm), 100% inspection was necessary.
-NTK 650 grade provides a better surface finish and excellent anti-adhesion properties, reducing wear caused by built-up edge. As a result, it achieved 5 times longer tool life and stable machining.
Moreover, full inspection was no longer needed, improving productivity and reducing inspection costs.
