Cutting tool coating is a kind of important material in machine tool ＆ tools industry and its performance will determine the machining accuracy of CNC machines. The coating material characteristic, the request and the coating technology development of the cutting tool were briefly introduced. The good and bad points of CVD, PVD, PECVD and the Sol-Gel method were analyzed specifically. Unifying the present situation and the trend of the development of the cutting tool coating at home and abroad, it pointed out a new craft should be developed in which both CVD and PVD are unified while vigorously developing any one solely. By this way the domestic coating market will be impelled with a fast development.
