随着机械装置向高速重载发展,工况条件更显恶劣,因此机械零件要使用高硬度耐磨损的新型材料,而且零件尺寸要精密、表面粗糙度要低;这往往难以用传统的磨削加工工艺来达到。解决的方法,一是使用硬度高、耐磨度高的磨料制造的砂轮,如金刚钻或立方氮(?)硼砂轮,这是目前广泛使用的工艺方法。另一途径,是近年来一直在研究的联合能量磨削,既能加工出高精度尺寸的表面,还可提高磨削效率。这 With the development of mechanical devices to high-speed heavy-duty, working conditions even worse, so the mechanical parts to use a new type of high hardness and wear-resistant materials, and parts to be precise size, surface roughness is low; it is often difficult to use traditional grinding Cutting process to achieve. The solution is to use a grinding wheel made of abrasive with high hardness and high abrasion resistance, such as diamond or cubic boron nitride wheel, which is currently widely used. Another approach is the joint energy grinding that has been under study in recent years, both to produce surfaces of high precision size and to improve the grinding efficiency. This
