目前在沟轴磨床上磨花键拉刀的方法被广泛采用的是成形磨法(图1),这种方法的特点是生产效率高,精度高。但是需要有专门的修正砂轮的夹具。这种夹具一般都安装在机床的床面子上,使用阿非常麻烦。我厂应用的修正砂轮夹具改安装在砂轮轴上;因而修正砂轮方便,提高了生产效率,并可以 At present, the method of grinding a spline broach on a groove-shaft grinding machine is widely adopted by a forming mill method (FIG. 1). This method is characterized by high production efficiency and high precision. But need to have a special fixture correction wheel. This fixture is generally installed on the machine bed, the use of a very troublesome. I modified the application of the grinding wheel fixture installed on the shaft in the modified; thus modified wheel convenience, improve production efficiency, and can
