高精度工件的自动加工,很大程度上是由于采用了精密磨削才成为可能;但如果没有一种高速而精确地修整砂轮的金刚石修整器,那么广泛地采用精密磨削同样是不可能的。目前存在着一个严重问题,使人越来越感到棘手。在现代工业的一些关键部门中,要求形状千差万别的工件。这些工件需要经过磨削加工达到精确尺寸,光洁度的要求往往也很高。因此,必须没法在砂轮上把这些形状修整出来。在使用金刚石笔修整砂轮的时候(图1),需要使用象缩放仪或随动凸轮那样的仿形器。从生产的观点看,这些装置都有严重的缺点,可归结为:1.原始造价高;2.运动速度慢;一个 The automatic machining of high-precision workpieces is largely due to the use of precision grinding; however, the widespread use of precision grinding is equally impossible without the use of a diamond dresser that trims the grinding wheel at high speed . There is a serious problem that is making people feel more and more thorny. In some of the key sectors of modern industry, workpieces of widely varying shapes are required. These parts need to go through the grinding process to achieve the exact size, the requirements of the finish is often high. Therefore, these shapes must not be trimmed on the grinding wheel. When using a diamond pen dressing wheel (Figure 1), a profiler such as a pantograph or follower cam is required. From the production point of view, these devices have serious shortcomings, can be attributed to: 1. The original high cost; 2. Slowly moving; a
