diamond wood cutting tool for solid wood floor

Boron nitride is an excellent tool material for processing iron metal and alloy, and boron nitride (PCBN) is a polycrystalline composite substrate with alloy substrate at the bottom.

The hardness of the cubic boron nitride sintered is generally 3500 ~ 4000Hv, ceramic. 2400 Hv, hard alloy 1800 Hv. High hardness brings good abrasion resistance. In general, the wear resistance of cubic boron nitride is 30 times as high as coating alloy, 50 times as much as non-coated carbide, and 15 ~ 20 times of ceramic blade.

Cubic boron nitride cutting under the high temperature of 1000 DHS C, its surface will not produce oxidation, extent of the high temperature hardness is much smaller than cemented carbide and ceramic blade, this will create conditions for high speed cutting. Cubic boron nitride chemical inertness, particularly large in neutral medium, the air is stable to acid and alkali, in 2000 DHS doesn't react with carbon and with iron clan materials in 1200 DHS C ~ 1300 DHS C doesn't response for cutting ferrous metal materials.
