Abstract
Machining apparatus for machining a workpiece with a work-performing tool comprising a frame on which a tool carrier is mounted for reciprocal movement toward and away from the workpiece and a feed unit for moving the tool carrier between a partially retracted position and a fully retracted tool change position and for moving the tool carrier from the partially retracted position reciprocally through a machining stroke to machine a workpiece. The feed unit includes a drive transmitting assembly which is reciprocally mounted on the frame and which comprises extensible and contractible means connected to the tool carrier. A first drive means reciprocates the drive assembly while the extensible and contractible means remains fixed so as to move the tool carrier reciprocally through a machining stroke and a second drive means actuates extensible and contractible means to move the tool carrier between its partially and fully retracted positions.
