Coating the tool is one of the important ways to improve the tool performance

The appearance of coating tool has made a great breakthrough in cutting performance. Coating tool is in the toughness of the tool body, coated with a layer or multiple layers of refractory compounds with good wear resistance, it combines the tool matrix and hard coating, so that the performance of the tool is greatly improved. Coating tool can improve machining efficiency, improve machining accuracy, prolong tool life and reduce machining cost.
