Spline shaft processing methods: sp

Spline shaft processing methods: spline shaft processing methods are many. Mainly using rolling, milling, grinding and other cutting methods, can also use plastic deformation processing methods, such as cold stamping and cold rolling.Hobbing method: spline hob is used in spline shaft milling machine or gear hobbing machine according to the generating method of spline. The method has high productivity, high precision and is suitable for mass production.Milling method: in the universal milling machine, with a special form of milling cutter directly milling out the profile of the teeth, and use the dividing head to separate the teeth, milling teeth; If you do not use forming cutters, you can also use two disc cutters to cut both sides of the teeth at the same time, and then after milling with the teeth, use a disc cutter to trim the bottom diameter slightly. Milling method of low productivity, low precision, mainly used in small batch production of a single spline shaft to the outside diameter as the center of the rough machining, and then hardening.Grinding method: grinding the side and bottom diameters of splines on a spline spindle grinder with a shaped grinding wheel. It is suitable for machining hardened spline shafts or spline shafts with high precision requirements, especially those centered on the inner diameter.
