PCBN cutting tool application examples

As cubic boron nitride high hardness and wear resistance, high temperature does not react with the iron group metal chemical inertia, so the main material for high hardness and

cutting difficult materials, such as hardened steel, high alloy wear cast iron, high temperature alloy, high speed steel, surface spray

Welding materials, sintered metal materials and other difficult materials cutting.
(A) processing of hardened steel, can play in turning instead of grinding effect, because the grinding depth greater than the depth of cut more than ten times, so high

processing efficiency, the surface does not produce burns. If turning instead of grinding speed sliding gear (20CrMnTi, hardness HRC58 ~ 62), the cut

Cutting grinding efficiency than the original four times.
(2) high-alloy (tungsten or chromium 18%) cast iron, carbide cutting speed compared to more than 10 times, more than four times the cutting efficiency.
(3) processing of high-cobalt-chromium-molybdenum corrosion resistant alloy, PCBN cutting speed is 160m/min, is eight times carbide cutting tools .
(4) Processing thermal spraying (spray) materials, surface grinding spray member can not be used, but with low efficiency carbide cutting tool, switch after PCBN tools

improve processing efficiency, to save processing costs more than 50%. PCBN tools can be used to close the essence of non-ferrous metals

Cut and sintered metal cutting and so on.
