Description

Vitrified bond CBN grinding wheels
Introduction of Vitrified bond cubic boron nitride (CBN) grinding wheel
Properties of cubic boron nitride(CBN):
1. The hardness of cubic boron nitride (CBN) is second only to the diamond
2. In the air, CBN can resistance to high temperature 1400 to 1600, it can withstand the high toughness of hard processing material grinding heat.
3. CBN chemically inert, under 1100 doesn't react with transition metal and therefore will not appear when grinding or cutting iron material such as diamond chip sticking phenomenon, which decides it is very valuable when grinding steel abrasive.
4. The thermal conductivity of CBN is good.

Characteristics of Vitrified CBN grinding wheel:
1. With large elastic modulus, small thermal expansion, good toughness, small deformation and good shape retention, the grinding wheel can be added with accurate size and good surface finish.
2. The grinding wheel has a porous internal structure, and the binding agent has a strong control force on the CBN.
The grinding wheel has sharp cutting force and small grinding force.
The surface of the workpiece is in a state of compressive stress, which increases the compressive and fatigue strength of the workpiece and the workpiece durability by 10-30%.
3. After high temperature sintering, the grinding wheel has strong control over CBN abrasive particles. Therefore, the grinding wheel has an extremely long service life, and its durability is 30-100 times that of corundum grinding wheel.
4. The grinding wheel has high strength and good shock resistance, high strength of joints, and soft elastic layer at joints of joints is conducive to the elimination of grinding stress and grinding heat, so that the grinding wheel can adapt to high-speed grinding and the linear speed can reach over 60m/s.
