用刚玉砂轮磨削超硬高速钢,困难重重;而用立方氮化硼砂轮,则能顺利地进行磨削。与刚玉砂轮相比,立方氮化硼砂轮磨削超硬高速钢时,磨削力、磨削温度均较小,并能改善磨削条件,但表面粗糙度略高,这可从立方氮化硼磨料的优异性能予以解释。实验证实,用立方氮化硼砂轮磨削超硬高速钢是适宜的。 Corundum grinding with high-speed hard steel, difficult; and with cubic boron nitride grinding wheel, you can smooth grinding. Compared with corundum grinding wheel, CBN wheel grinding super hard high-speed steel, grinding force, grinding temperature are small, and can improve the grinding conditions, but the surface roughness is slightly higher, which can be from the cubic nitride The excellent properties of boron abrasives are explained. Experiments confirmed that the use of cubic boron nitride grinding wheel super-hard high-speed steel is appropriate.
