Metal spinning

Hollow parts with almost any surface contour

One roller does it all: Metal spinning involves a spinning roller carrying out multiple passes. The planishing pass gives the workpiece its final shape.

1. Setting the process in motion:

A pressure plate clamps the preform (or circular blank) centrally against the spinning tool. The main spindle and clamped preform start to rotate.

2. Spinning and planishing:

The spinning roller is applied to near the center of the preform. It moves gradually towards the circumference of the preform with repeated passes until the preform is flush on the spinning tool. The process is concluded by a planishing pass, which gives the workpiece its final shape.
