随着无心磨削技术的发展,越来越多的带轴肩,阶梯形及轴向为曲线形状的回转体工件,由原来采用外圆磨削工艺转而采用无心切入磨削工艺,这种加工方法不用中心孔定位,又可用多片砂轮磨削,生产效率比一般的外圆磨床要高,为自动磨削提供了很大的方便性,特别是在大批量生产中,更显示它的优越性。而且这种趋势还在不断的发展,所以研究各种带轴肩、阶梯形及轴向为曲线形状的回转体工件的无心切入磨削工艺上的技术规律就很有必要,而如何保持工件定位系统的稳定性
With the development of unmotivated grinding technology, more and more rotating body workpieces with shoulders, step shapes and axial curvilinear shapes have been converted from cylindrical grinding to centerless grinding, Processing methods do not have the center hole location, but also with multiple grinding wheel, the production efficiency than the average cylindrical grinder to provide a great convenience for automatic grinding, especially in mass production, but also shows its Superiority. And this trend is still undergoing continuous development. Therefore, it is necessary to study the technical rules of the centerless grinding process of various rotary bodies with shoulders, step shapes and axial curvilinear shapes, and how to maintain the workpiece positioning System stability
