Advantages of cold rolling mandrel compared with traditional Spline Milling
Cold extrusion spline processing:
Replacing traditional mechanical cutting methods with advanced cold extrusion technology is a qualitative leap in the spline machining process. It not only improves the machining accuracy and surface finish, but also greatly improves the mechanical properties of the parts. The cold work hardening of the metal after cold extrusion and the formation of a reasonable fiber streamline distribution inside the part make the spline strength much higher than that processed by mechanical cutting. Through the test, the mandrel processed by the process has a load-bearing torque of 25-30%, and the accuracy is improved by two levels, achieving the national standard six-level accuracy. In addition, a reasonable cold extrusion process can form compressive stress on the surface of the part to improve fatigue strength.
