一、前言 近年来,随着机床、汽车、仪表和化学纤维工业的发展,对齿轮精度和噪声的降低要求越来越高,需要磨削的齿轮越来越多。因此,发展高效率的蜗杆砂轮磨齿机是迫切的任务。可是,蜗杆砂轮磨齿机一般是采用大颗粒天然金刚石刀进行砂轮成型修整的,而这种金刚石货源少、价格贵, I. Introduction In recent years, with the development of machine tool, automobile, instrument and chemical fiber industry, the requirements on the reduction of gear accuracy and noise are getting higher and higher, and more and more gears need to be ground. Therefore, the development of efficient worm wheel grinding machine is an urgent task. However, the worm wheel grinding machine is generally used with large particles of natural diamond grinding wheel dressing, and this diamond less supply, the price is expensive,
