Abstract
A chuck has a plurality of top jaws for engaging a workpiece. Each top jaw has a recess and a slot that extend completely through the top jaw. The recess and slot allow the forward end of the top jaw to deflect in a rearward direction. This motion allows the jaws to maintain even pressure on the workpiece instead of cocking, thereby minimizing deflection of the workpiece during machining. The slot defines a rearward facing shoulder on the forward end. The maximum deflection of the forward end is limited by the width of the slot. The distance of deflection may be limited by pins located within holes extending through the jaw perpendicular to the slot.
