立方氮化硼(CBN)是由六方氮化

硼在50-90kbr 和***0-2700C条件下合成所得的一种类似于金刚石的人造材料.作为世间***坚硬的物质,CBN能以***的***度磨削超硬铁,合金钢以及坚硬的脆性材料,特别适用于难以磨削或HRC≥50的高合金淬火钢如:

高速钢,工具钢或镀铬钢,硬铸铁. CBN的热稳定性在1200°C.为避免超硬磨料的氧化和石墨化,避免磨料性能减弱,我公司陶结合剂为***研制Y39.可在750C以下制成,以保证制品的稳定性,发挥超硬砂轮的耐磨性好,修整频次低和磨削精度高的作用.陶瓷结合剂CBN砂轮因CBN磨料高硬度的特性,具有***,高精度，低频调整的性能,广泛用于汽车零部件加工企业,如曲轴,凸轮轴,齿轮轴,空调压缩机等行业.我公司汽油机曲轴加工钢件可达150-200件修整/2μ/次5-10次.

Cubic boron nitride (CBN) is a kind of diamond-like artificial synthesized from hexagonal boron nitride  at 50-90kbr and ***0-2700°C. As the hardest

material in the world, CBN can grind superhard

iron , alloy steel and hard brittle materials with the    highest accuracy, especially suitable for high-alloy   quenched steels that are difficult to grind or HRC     50 such as: high-speed steel, tool steel or chrome- plated steel and hard cast iron. CBN thermal

stability is at 1200°C, and in order to ***oid the

oxidation and graphite of superhard abrasives,

***oid the weakening of abrasive performance, our company's ceramic binder is the exclusive Y39,

which can be made below 750°C to ensure the

stability of products, and play the role of good wear resistance of superhard grinding wheel, low

dressing frequency and high grinding precision.

Ceramic bond CBN grinding wheels due to the

characteristics of high hardness of CBN abrasive, h***e high efficiency, high precision and low

frequency adjustment performance, and are widely used in auto parts processing enterprises, such as crankshaft, camshaft, gear shaft, air conditioning    compressor and other industries. Our campany's    gasoline engine crankshaft processing steel parts   up to 150-200 pieces dressing /2 μ/ 5-10 times.
