Product Description

 High Torque with high strength and precision Ra 0.8 Finish Cold Rolling Shaft

With the development of the twin screw extruder towards high speed and high torque, the strength (especially the thermal strength) and precision of the twin screw extruder shaft are required higher. Through extensive research, the material we use Germany imported pre-hard alloy tool steel and the splines are formed with Europe imported CNC spline cold rolling processing equipment. After customer trial, products fully meet the performance and quality requirements of similar high-end products imported from abroad.


1. Shaft Range

Diameter: 35-120mm
Lenth: 500-14000mm

2. The advantages of cold rolling shaft compared with the traditional milling shaft

Using advanced cold rolling technology to replace the traditional milling to process splines is a qualitative leap in spline processing technology. It not only improves the processing accuracy and surface finish, but also greatly improves the mechanical properties of parts. After cold rolling, the strength of spline is much higher and reasonable fiber streamline distribution inside the parts can form compressive stress on the surface of parts and improve fatigue strength.
Through the test, the torque force of the shaft processed by this technology is increased by 25 ~ 30%, and the accuracy is increased by 2 levels, reaching the national standard of 6 levels. In addition, reasonable cold rolling process can form compressive stress on the surface and improve the fatigue strength.
