Abstract
PURPOSE: To provide a cutting-off device of high accuracy and long lifetime, by using balls and liners to support a coupling for moving a work in response to pressure at the final stage of outline cutting-off of the printed circuit board or the like and by enabling the putting-away of a whole pushing unit.
CONSTITUTION: At the final stage of outline cutting-off of a printed circuit board 1 or the like, the workpiece 1 is pushed by a pushing unit to heighten the accuracy of the machining. A coupling 10 is supported with balls 12 and liners 11 on a pressure hoot 9 to which pressure is applied by a pressure cylinder 8, so that the coupling can be lightly moved horizontally. The pushing unit can be completely put away from the position of the axis of a spindle by a vibratory cylinder 26. According to this constitution, the pressure following action of the coupling 10 at the final stage of the cutting-off is ensured. To replace a tool, the pushing unit is put away to prevent a new tool from eccentrically attached due to dust or the like.
