Centering device having work rest control responsive to carriage detection means

摘要

A centering device includes a plurality of work rests disposed along the longitudinal direction of a bed of a lathe. Each of the work rests is movable between a first position for supporting a work and a second position spaced from the work. A control device is associated with the work rests for controlling movement of each of the work rests between the first position and the second position in response to the movement of a carriage.
