1前言近年来，随着难磨金属材料使用的增加，仅使用普通磨具已难以满足磨加工新的要求。虽然CBN砂轮在加工难磨金属材料方面具有卓越的性能，但由于其价格昂贵，目前还难以普遍采用。从国内外的资料和我们以前的一些初步研究和应用中，我们知道刚玉和碳化硅混合磨料陶瓷砂轮， 1 Introduction In recent years, with the increased use of refractory metal materials, the use of ordinary abrasive grinding has been difficult to meet the new requirements. Although CBN grinding wheels have excellent performance in the machining of hard-to-grind metal materials, they are still not universally adopted due to their high cost. From domestic and foreign information and some of our previous preliminary research and applications, we know that corundum and silicon carbide hybrid abrasive ceramic wheel,
