Processing of torch-shaped spline ring gauge keyway

October 15, 2018

The rectangular spline ring gauge is a comprehensive gauge that controls the working surface size and shape tolerance of the rectangular external spline. It is used in large-volume production to test the assembly and interchangeability of splines, and is easy and accurate to use. In the case of a spline size inspection, the looser the workpiece passed by the ring gauge, the smaller the geometric tolerance of the spline. The basic processing technology of the rectangular spline ring gauge is: blanking - pre-heat treatment - car - milling - heat treatment - grinding inner hole - grinding key groove. The key process is to grind the keyway, the size and shape tolerance are not
