Customized cold pilger mill technology The KPW 370 L operates at 65 strokes per minute and has a drive power of up to 1.55 megawatts. The 44-ton mill stand moves forward and backward 65 times a minute.
The pilger mill system was designed to use index- able servo motors that are connected to the large drive rolls directly. This design allows for more flexibility in the degree and speed of die rotation. The following four figures depict the modifications that were done to the rolling mill to create the PNNL lab-scale pilger mill.

1. Introduction. Cold pilgering is a popular cold working process for metallic tubes. Stinnertz (1988) reported that it is widely applied to the manufacture of seamless tubes, including tubes made of steels and copper, titanium, and zirconium alloys. A large cross-sectional reduction of more than 70% is possible in cold pilgering, comparable to that in cold drawing.
The mandrel of our cold pilger mill is made of Cr12. Roll Pass Design and machining of roll pass has direct influence on the quality and precision of the finished tubes.
