在万能铣上加工齿轮,由于用仿形法切削,齿形精度较低,有条件者一般不采用。但很多工厂没有齿轮加工机床,仍以万能铣做为加工齿轮的主要设备。实际生产中,铣削加工的螺旋齿轮,常出现齿轮付啮合不良现象,不少同志认为是铣床加工方式的先天性缺陷,无法解决。本文着 Milling on the universal gear, due to the use of profiling cutting, low profile accuracy, the conditions are generally not used. However, many factories do not have gear processing machine tools, milling is still used as the main processing gear. In actual production, the helical gears that are milled and machined frequently appear gear mismatches, and many comrades think it is a congenital defect in milling machine processing that can not be solved.
