There are many kinds of CNC machining methods for spline shafts. It mainly adopts cutting processing methods such as hobbing, milling and grinding. Plastic deformation processing methods such as cold hammering and cold rolling can also be used.
1. Hobbing method: Use spline hobs on spline shaft milling machines or gear hobbing machines to process according to the generative method.
2. ಮಿಲ್ಲಿಂಗ್ ವಿಧಾನ: direct milled teeth formed with a special contour on the universal milling cutter, with milling teeth by the tooth points dividing head; If not form cutter, can also be a two disk milling cutter teeth while both sides of the teeth by milling and then with a well bottom diameter of the disc cutters slightly trimmed.
3. Grinding method: Grind the spline tooth side and bottom diameter on the spline shaft grinder with a shaped grinding wheel.

3. Application examples: in brakes and steering mechanisms. There is also a telescopic shaft, which is composed of inner and outer tubes, the outer tube has internal teeth, and the inner tube has external teeth, which are sleeved together. When in use, it can extend and contract in the length direction while transmitting the rotating torque.
4. ವಸ್ತು: 40Cr.
5. Heat treatment: quenching surface hardness HRC45-50.
Type of spline shaft
Spline shafts are divided into rectangular spline shafts and involute spline shafts. Among spline shafts, rectangular spline shafts are widely used, while involute spline shafts are used for connections with larger loads, high centering accuracy requirements, and larger dimensions. Rectangular spline shafts are usually used in aircraft, automobiles, tractors, machine tool manufacturing, agricultural machinery and general mechanical transmission and other devices. Because the rectangular spline shaft works with multiple teeth, it has high load-bearing capacity, good neutrality and good guiding performance, and its shallow tooth root can reduce the stress concentration. ಜೊತೆಗೆ, the strength of the shaft and hub of the spline shaft is weakened, and the processing is more convenient, and higher precision can be obtained by grinding. Involute spline shafts are used for connections with large loads, high centering accuracy requirements, and large dimensions.
Its characteristics: The tooth profile is involute, and there is a radial force on the tooth when it is loaded, which can play a self-centering function, so that the tooth is uniformly stressed, with high strength and long service life. The processing technology is the same as that of gears, and it is easy to obtain higher precision and interchangeability.
