NTK PVD Carbide - Precision Machine Parts - ST4

By changing to high-speed, low-feed conditions, the processing time was reduced by approximately 40%. In addition, although the curl diameter of the chips was large and unstable, the chip entanglement trouble was also drastically reduced.
This resulted in a significant reduction in the chip volume, which also contributed to reducing the frequency of cleaning.
