Nowadays, the speed of technological development is getting faster and faster, the update time of products is getting shorter and shorter, and the production technology of many products is also constantly developing, such as spline shafts. There are many processing methods for it. Today I have compiled several comparisons. Common factory processing methods are for your reference.
- Grinding method: This processing method uses a shaped grinding wheel to grind the tooth side and bottom diameter of the spline on the grinder. For those spline shafts that require high accuracy, centering and hardening of the inner diameter, grinding can be used Sent for processing.
- Hobbing method: Use the knurling hob to process the spline shaft hobbing machine or milling machine according to the generative method. This processing method not only produces a higher spline shaft tibia, but also has a very high production efficiency. Suitable for mass production.
- Cold punching method: The cold punching method needs to be processed on a special machine tool. The specific processing method is to start the outside of the circumference of the workpiece. Note that the positions of the two ends of the head must be symmetrical. When the workpiece is rotated by one tooth at a time, then the top The beating will hammer the tooth grooves of the workpiece. After continuous hammering, the surface of the workpiece will be deformed, and finally a spline shaft will be produced.
- Milling method: Use a universal milling machine to directly mill the contour between teeth with a shaped milling cutter, and then use an indexing head to divide the teeth to mill each tooth. If there is no shaped milling cutter, you can also use two disc milling cutters. Milling is performed on both sides of a tooth of the spline shaft, but the milling accuracy is relatively low and the productivity is not high, so it is suitable for small batch production.
The above is the more commonly used spline shaft processing methods currently used by manufacturers. For details, please have a better understanding of its processing methods after reading it.
