          Spline Processing Method: There are many ways to process the spline shaft. It mainly adopts cutting methods such as rolling, milling and grinding, as well as plastic deformation processing methods such as cold beating and cold rolling.

          1. Hobbing method: Spline hobs are processed by generating method on spline shaft milling machine or hobbing machine. This method has high productivity and precision, and is suitable for batch production.

          2. Milling method: In universal milling machine, the profile between teeth is directly milling with a special form milling cutter, and the indexing head is used to divide teeth and milling teeth by teeth. If no form milling cutter is used, two disc milling cutters can also be used to milling both sides of one tooth at the same time, and then a disc milling cutter is used to trim the bottom diameter slightly after milling. Milling method has low productivity and precision, mainly used in small batch production to process spline shaft centering outside diameter and rough processing before hardening.

          3. Grinding method: Formed grinding wheel is used to grind the side and bottom diameters of spline teeth on spline shaft grinder. It is suitable for processing hardened spline shafts or spline shafts with higher precision, especially those centered by inner diameter.

          4. Cold beating: on special machine tools. The two heads symmetrically arranged outside the workpiece circumference are rotated at a constant speed ratio with the indexing rotation motion and axial feed of the workpiece. Each tooth of the workpiece is rotated at a high speed. The forming wheel on the head hammers the alveolar part of the workpiece once. Under the continuous hammering of the high-speed and high-energy movement of the wheel, the workpiece surface produces plastic deformation and splines.

          The precision of cold beating is between milling and grinding. The efficiency of cold beating is about 5 times higher than that of milling. Cold beating can also improve the utilization rate of materials. The above is a detailed explanation of the spline shaft processing method.
