ABSTRACT:
A bushingless workhead comprises a flexible drill collet inside a flexible chucking collet. The chucking collet has external frusto-conical surfaces on the ends thereof that mate with corresponding frusto-conical surfaces on a pair of pistons. The pistons are slidable within a housing away from each other to apply opposed forces to the chucking collet. The forces cause the chucking collet to collapse and to also collapse the drill collet to grip a tool inside the drill collet. One piston applies a greater force on the chucking collet than the other piston. The chucking collet is thus forced to move longitudinally in one direction, and it abuts a fixed reference surface that repeatably locates the chucking collet during each tool gripping operation prior to the chucking collet collapsing to grip the tool.
