Abstract

PURPOSE: To prevent an accident of damage of a hobbing cutter upon power failure, by providing an electromagnetic clutch in a workpiece power transmission system and a flywheel in a hobbing cutter power transmission system so that the workpiece power transmission system is isolated upon cut-off of system power source.
CONSTITUTION: A worktable 5 may separate a wheel therefrom by means of an electromagnetic clutch 21 disposed between the worktable 5 and the wheel 8. Further, a flywheel 22 aligned coaxially with a hobbing cutter 1 increases the rotational inertia force of the hobbing cutter 1. Meanwhile a power source cut-off detecting circuit 23 monitors a power source E for an NC device 9 to detect a power cut-off condition due to power failure, power cut-off manipulation or the like, and delivers a detection signal S for releasing a clutch 21. Accordingly, if the cut-off of power source occurs, a workpiece follows freely to the rotation of the hobbing cutter 1 so that they are both moderately decelerated in rotation at a rate which is substantially equal to that before the cut-off of power source, and are finally stopped at the same time.
