ABSTRACT:
Centering and wear compensating means for turret bores and the like. Plugs of a suitable resilient, long wearing, self-lubricating material are equiangularly placed in bores of uniform length provided in the wall of a turret bore in which a tool holder is positioned. The plugs are made long enough to be compressed into the bores by the tool holder when the tool holder is centered in the turret bore and are spaced along the turret bore such that engagement of the plugs with the tool holder will be maintained as the tool holder is raised and lowered in the turret bore. The plugs are curved on one end to conform to the tool holder surface and are chamfered to permit easy compressibility as the tool holder is positioned in the turret bore.
