Abstract
PURPOSE: To prevent decrease of holding power for workpiece by coupling a holding claw and a weight part with a lever supported to a chuck body and by negating centrifugal force working on the holding claw during high rotation operation with centrifugal force working on the weight part through the lever.
CONSTITUTION: T-shaped tapered part 16 of a weight part 12, inserted in a chuck body 1 to freely slide radially, is inserted into a T-shaped groove 22 of a wedge cylinder 21; the weight part 12 slides radially as the tip surface of the tapered part 16 is pushed up by the groove 22; a lever 18 seivels clockwise, and a holding claw 6 slides toward center to hold workpiece. Next, workpiece is revolved at high rate to operate cutting, when centrifugal force working on the holding claw 6 is negated by centrifugal force working on the weight part 12 through a lever 18, eliminating the decrease of workpiece holding force due to centrifugal force of the holding claw 6 during high speed revolution.
