几年以前在外圆磨削的工序中使用砂轮的线速度超过6500呎/分(32.5米/秒)时就不加区别地称为高速磨削及强力磨削。实际上这二个术语有不同的含义。高速磨削是指现在使用的淘瓷砂轮的高速圆周磨削,如每分钟12000吹呎(60米/秒),16000呎(80米/秒),18000呎(90米/秒),甚至更高的速度。目前用较抵的普通的砂轮速度作精密磨削的工件,如用高速磨削可改善磨削质量或提高生 A few years ago, when the linear speed of the grinding wheel in a cylindrical grinding process exceeded 6,500 feet per minute (32.5 meters per second), it was called high-speed grinding and intensive grinding indiscriminately. In fact these two terms have different meanings. High-speed grinding refers to the high-speed circumferential grinding of the currently used porcelain wheel, such as 12,000 feet per minute (60 meters per second), 16,000 feet (80 meters per second), 18,000 feet (90 meters per second) or even more High speed. At present with a relatively ordinary wheel speed for precision grinding of the workpiece, such as grinding with high-speed grinding can improve the quality or improve students
