ABSTRACT:
A spinning method which makes it possible to control the pressing force of a roller tool with satisfactorily high responsiveness and have the roller tool press work following the contour of a forming die even if the die may have its radial length vary at a high speed relative to the angle of its rotation when making a product which is not circular in its cross section normal to the axis of rotation of the die, and an apparatus therefor. The roller tool is driven by at least two mutually crossing linear motors and the thrust to be generated by each linear motor is adjusted to control the feeding displacement of the roller tool and the pressing force of the roller tool against a piece of work.
