Method for manufacturing workpieces and spinning machine therefor

The method involves slidingly placing a portion of a preform (8) onto a mandrel (4), and aligning the mandrel such that a surface (3b) placed within the preform defines a negative profile of an inner surface to be formed in the preform. A relative movement is caused between the preform and a pressur...

Zusammenfassung:	The method involves slidingly placing a portion of a preform (8) onto a mandrel (4), and aligning the mandrel such that a surface (3b) placed within the preform defines a negative profile of an inner surface to be formed in the preform. A relative movement is caused between the preform and a pressure roller (7) in a direction parallel to a longitudinal axis, such that material of the preform is displaced by the pressure roller in such a way that the mandrel is moved longitudinally along the longitudinal axis by the displaced material. An independent claim is also included for a flow-forming machine for producing workpieces, comprising a mandrel.
