Inner hole broaching machine processing, spline products processing

The machining process of an inner spline is called slotting. In this casting process, the spline teeth are shaped so that the tooth arcs align with the spline axis. The spline is crowned in the male, which means that the diameter is the same as the thickest tooth arc. The diameter of the female spline is flat, and it is uncrowned in the opposite direction.

The spline’s teeth will be machined in the opposite direction to the outer spline. The spline’s profile will not be affected by the cutting process. During the spline slotting process, the raw material is placed into an indexing fixture of the milling equipment. The milling machine is then equipped with two side milling cutters. The spline’s shaft will be centered between the cutters.For internal splines, the slotting process is used. The slotting tool reciprocates along a parallel axis.

In both the internal and the external spline, a slotting tool is used. The spline tool reciprocates on a parallel axis while the part is rotated. The slotting process is repeated until all the spaces are machined. It is possible to use this same method for external splines, but in most cases, other methods are more effective. The most popular method is spline machining.
