CBN abrasive is mainly used for steel parts, such as high speed steel, die steel, 45 steel, etc., can be made into electroplating CBN, resin CBN, sintered CBN. Can be made into grinding wheel, cutting pieces, grinding head. Abrasive sharp, high temperature resistance, good thermal stability, wear resistance. The hardness of CBN is higher than that of ordinary abrasives and the ability to maintain shape is one of the main characteristics of high performance abrasives. CBN is very resistant to pressure. CBN has good thermal conductivity and can achieve cold cutting during grinding.
strong wear resistance, long life
The grinding ratio of CBN wheel can reach 3500-5500, which is 100 times higher than that of ordinary corundum wheel and 3-5 times higher than that of diamond wheel.
environmental protection, no pollution, energy saving and consumption reduction
No too much powder dust.
High work efficiency and good comprehensive economic benefits
The grinding is sharp, the grinding force is small, the dressing cycle of CBN wheel is long, the dressing amount is less, and the replacement time is long. Long service cycle, high grinding ratio, can obtain better economy, good shape retention in use, do not need to change and trim grinding wheel often, save working hours, improve working conditions, is conducive to machining operation.
Cubic boron nitride is not suitable for grinding hard metals and non-metallic materials. At high grinding temperature, CBN will react with alkaline aqueous solution. CBN grinding wheel will decompose in alkaline solution at 300℃, and can decompose in trace amount in boiling water, which will destroy the crystal shape of grinding grains. Therefore, oily coolant should be used instead of water-based coolant during grinding.
