TBI ball spline SOT025 machining method: There are many machining methods for spline shafts. Mainly using cutting methods such as rolling, milling, and grinding, as well as plastic deformation processing methods such as cold rolling and cold rolling.

1. Rolling method: Use TBI spline shaft SOT025 rolling cutter to machine on spline shaft milling machine or hobbing machine according to the unfolding method. This method has high productivity and accuracy, and is suitable for mass production.

2. Milling method: Use a specialized forming milling cutter to directly mill the tooth profile on a universal milling machine, and use a dividing head to divide the teeth and mill them one by one; If a form milling cutter is not used, two disc milling cutters can be used to mill both sides of one tooth at the same time. After milling each tooth, a disc milling cutter can be used to slightly adjust the bottom diameter. The productivity and accuracy of milling method are relatively low, mainly used for machining TBI ball spline shafts with outer diameter centering in single piece and small batch production and rough machining before quenching.

3. Grinding method: Use a formed grinding wheel to grind the spline tooth side and bottom diameter on the spline shaft SOT025 grinder, suitable for processing hardened spline shafts or spline shafts with higher precision requirements, especially those centered on the inner diameter. 4. Cold play method: carried out on specialized machine tools. The two punch heads symmetrically arranged on the outer circumference of the workpiece rotate at a constant speed ratio with the indexing and axial feed of the workpiece. Every time the workpiece rotates one tooth, the forming punch wheel on the punch head strikes the tooth groove of the workpiece once. Under the continuous hammering of the high-speed and high-energy motion of the punch wheel, the surface of the workpiece undergoes plastic deformation and forms a spline. The precision of cold drawing is between milling and grinding, with an efficiency about 5 times higher than milling. Cold drawing can also improve material utilization

Taiwan TBI flange type ball spline SOT025, with a spline diameter of 25mm, can be divided into hollow spline shaft and solid spline shaft TBI spline shafts are named after their appearance, with longitudinal key slots on the outer surface of the shaft and corresponding key slots on the rotating parts fitted onto the shaft, which can maintain synchronous rotation with the shaft.
