Due to the high-temperature, high-pressure, high-speed work, and the corrosive fluid medium parts, its application more and more difficult to machine materials, increasing the level of automation of the cutting and machining accuracy. To accommodate this situation, the direction of development of the tool will be the development and application of a new cutting Toolmaterial; vapor deposition coating technology, further development of the tool in a higher hardness of the coating is deposited on a substrate of high toughness and high strength, to better address contradiction between the hardness and strength of the tool material; further development of indexable cutting tools structure; improve the the Honing stone manufacturing accuracy and reduce the differences in product quality, make use of the tool to achieve optimization.
