磨齿机一般都设有工作分度,手动分度和连续分度功能,而多为单分度,即分一度,齿轮工件转过一齿,在砂轮与齿轮相对运动中磨削齿面,直至一个循环结束。单分度型式的磨齿机适用于磨削齿数较多的工件,为了扩大磨齿机使用范围,实现少齿数(如Z<10)磨削,便出现了双分度,即分度二次 Gear grinding machines are generally equipped with work indexing, manual indexing and continuous indexing functions, but mostly single-indexing, that is, once the gear workpiece turned a tooth, the relative movement of the grinding wheel and gear grinding tooth surface, Until the end of a cycle. Single-indexing type grinding machine is suitable for grinding workpieces with more teeth. In order to enlarge the use range of the grinding machine and achieve less grinding (such as Z <10), double indexing occurs
