ABSTRACT:
A forming wheel carriage for a CNC controlled metal spinning machine having a forming wheel post arranged to be movable relative to a second slide, and a process for operation of the metal spinning machine. During operation the forming wheel post is attached relative to the second slide by means of a ball flexibly mounted on the second slide engaged into a recess of the forming wheel post. The ball deflects backwards during overload, and the forming wheel with the forming wheel post can deflect immediately relative to the second slide. The forming wheel post deflects within a horizontal plane in accordance with a pre-selected force independent of the direction of the overload force. The force can be changed during an overload at a relief valve by means of a control unit by way of a control line. This manner of attachment of the forming wheel post allows for an automatic registering of the spindle tool contour. The contour is recorded point by point. This entails the repeated passage of the wheel with minimal push against the spindle tool. In addition, the positioning means serves as an overload check and emergency shut off switch.
