Abstract:

An apparatus for sensing sufficient chucking stock in a rotating work-holding chuck having a self-contained circular plate assembly adapted to the face of the work-holding chuck, wherein a clearance bore is provided through the plate assembly to permit passage of machining stock and a radially movable indicator pin is provided within the plate assembly to detect the presence of machining stock within the clearance bore. The radially movable indicator pin will urge a trip plunger out of the circumferential surface of the plate assembly when no stock is present, and a limit switch will be tripped by the trip plunger to signal the absence of chucking stock.
