    1: Ceramic Bonded Cubic Boron Nitride (CBN) Wheel introduction

    Properties of cubic boron nitride:

    1. The hardness of Cubic boron nitride (CBN) is second only to diamond, and it has strong oxidation resistance.

    2. In the air, CBN can withstand high temperature 1400 -1600 , also can withstand the grinding heat of materials with high toughness.

    3. CBN has good chemically inert and does not chemically react with transition metals below 1,100 ° C, so that there is no sticking as diamond when grinding or cutting ferrous materials.

    4. CBN thermal conductivity is good.

     

    The characteristics of ceramic bond CBN wheel:

    1. The elastic modulus of CBN grinding wheel is large, and it has small thermal expansion, good toughness. The shape retention is good; you can get precise size and good surface finish.

    2. Vitrified bond CBN wheel has porous inner structure. The binding agent on the CBN has a strong hold. Cutting is sharp, grinding force is small. The grinding wheel maintains high grinding efficiency to avoid the surface burn and micro-cracks. Workpieces surface will be in the state of compressive stress, which improves the anti-fatigue fatigue strength. Thereby the durability increases 10% -30%.

    3. After sintering in the high temperature, CBN abrasive hold is strong, so the wheel has a long service life. The durability is 30-100 times than corundum wheels.

    4. Grinding wheel is with high strength, good impact resistance. Nodular strength is higher, and the knuckle joints soft elastic layer is conducive to the elimination of grinding stress and grinding heat so that the wheel can adapt to high-speed grinding. The linear speed can reach more than 60m / s.

    Processing object:

    Ceramic CBN grinding wheel is suitable for processing hard high-speed steel, heat-resistant steel, stainless steel, high strength steel, high temperature alloys and other materials that is difficult to process. Also it is used for grinding automotive, aerospace, tools, cutting tools, bearings, gears, threads and other areas.
