CNC Turning Machining Pressure Roller

Precision CNC Turning Parts – Pressure Roller is a core component of conveying systems. It achieves stable material gripping and conveying by applying controllable pressure.

Customer Pain Points:
When S45C and bronze are thermal interference fitted, the bronze (with its higher expansion) produces greater stress on the S45C steel (with less expansion), resulting in plastic deformation of the steel sleeve. Moreover, after cooling, the difference in shrinkage causes the fit to be either too tight or too loose.

Solution:
Use a cold press fit, achieving a precision fit by applying pressure with a hydraulic press at room temperature. Because there is no need to heat the parts, the original mechanical and physical properties of both S45C steel and bronze are maintained, ensuring the overall strength, wear resistance, and precision of the roller.

Results:
Fit failure rate decreased by 97.5%, and overall cost reduced by 18%.
