Copper Tube Making Machine , High Efficiency Cold Pilger Mill For Reducing Tubes
Pilger mill machine reduces tubes from diameter of 70mm and wall thickness of 10mm to diameter of 40mm and wall thickness of 2mm. Due to that the pilger mill coefficient of elongation is very high, the deformation of pointing do not require very high.
Features of pilger mill machine as:
