Description

 Due to the high hardness PCBN and wear resistance, under high temperature not react with iron family metal chemical inert, so is mainly used for high hardness material and machining difficult-to-machine materials, such as a hardened steel, high alloy wear-resisting cast iron, high temperature alloy, high speed, surface spray welding materials, metal materials sintering difficult-to-machine materials of cutting processing.

(1) processing hardened steel, can have the effect of grinding car generation, because the cutting depth than grinding depth more than ten times above, so the processing efficiency high, the surface does not produce burns. Such as the car and grinding variable speed sliding gears (*0 CrMnTi, hardness is HRC*8 ~ *2), than the original cutting efficiency grinding four times as much.

(2) processing high alloy (including tungsten or chromium *8%) wear-resisting cast iron, cutting speed is cemented carbide cutting tools increased *0 times above, cutting efficiency improving 4 times as much.

(3) processing high cobalt chromium molybdenum corrosion resistant heat resistant alloy, PCBN tool cutting speed for **0 m/min, is carbide cutting tools of 8 times.

(4) processing thermal spraying (spray welding) material, the surface spray welding can not use grinding machining, and carbide cutting tools cutting efficiency is very low, PCBN after cutting tools to improve manufacturing efficiency can, save process costs more than *0%. PCBN tools can also be used in nonferrous metal precision cutting and sintering metal cutting processing, etc.
