ABSTRACT:
In this spinning lathe, the force exerted by a wheel on the workpiece is constantly supervised by one or more force sensors which furnish an instantaneous force signal to a servo-loop which controls the movement of the wheel in a direction transverse to the axis of rotation of the lathe. The set signal of the servo-loop is generated by a generator which may be actuated manually or operate automatically in accordance with a program. The servo-loop controls the force to be exerted by the wheel by means of a cylinder device supplied with fluid through a controlled valve.
