Abstract

PURPOSE:To finish surface roughness of a work very satisfactorily, by detecting the force pressing the work against a mandrel by a roll, and driving the roll so that its value becomes a prescribed value. CONSTITUTION:When a work 1 is put into a spinning working device 10 and is worked by a roll 3, a detecting device 11 detects pressing force of the roll 3 and inputs it to a deciding and operating device 12. Subsequently, the deciding and operating device 12 processes the pressing force as data, and calculates a moving locus of the roll 3 so that a value of the roll 3 becomes a prescribed value. Subsequently, in accordance with the data of the calculated moving locus, an NC driving device 13 presses the roll 3 against the work 1 by prescribed pressing force, and executes the spinning working.
