Application of cemented carbide tools


Hard alloys can be used in the chemical vapor deposition method has been coated with titanium carbide, titanium nitride, aluminum oxide hard or composite layer. Is the development of physical vapor deposition method can be not only used for hard alloy tool, can also be for high-speed steel cutting tools, such as drill hob, taps and milling. Hard coating as hinder chemical diffusion and heat conduction of the barrier, the cutting tool in the cutting wear slower. The life of blade coating and coating compared to increase about 1 ~ 3 times

Because in high temperature, high pressure, high speed, and in corrosion of fluid medium, the parts, the application of difficult to machining materials more and more, the level of automation of machining and on machining accuracy requirements become more higher.


In order to adapt to the situation and direction of development of the tool will be the development and application of new cutting tool materials; further development tool of gas phase deposition coating technology, with high strength and high toughness matrix deposition higher hardness of the coating, the better to solve tool material hardness and strength of the spear shield; in the further development of the structure of indexable tool; improve the manufacturing precision of the cutting tool, reduce the difference between the quality of the products and make the tool used to achieve optimization.
