With the rapid development of aviation, high-speed rail, makes high-precision grinding tools also needs innovative in terms of the choice of materials to its cautious. First, take the cubic boron nitride cutting wheel material selection terms: CBN, boron nitride is a second only to diamond in hardness and thermal stability than super abrasive diamond. The participation of a catalyst, in 6GPA-7GPA hypertension and 1400 ° -1500 degrees under the temperature conditions of the hexagonal boron nitride converted to cubic boron nitride, cubic boron nitride grinding wheel hardness and chemical properties is particularly suitable for grinding of ferroalloys and Other aerospace materials. Further, cubic boron nitride grinding wheel also applies to glass, ceramics and other production areas. Cubic boron nitride grinding wheel will play an important role in the future of industrial development in the role.
