Abstract

PURPOSE:To simplify the machining of a long workpiece by providing the primary main spindle rotating with the workpiece held on it, the secondary main spindle which is provided on the same center line as the primary main spindle and relatively approachably toward the primary main spindle, and has a chuck at its mouth, and a center supplying means. CONSTITUTION:In the case of machining a long workpiece, the workpiece 3 is supported by a center 30 which is transferred from a tool holder 19 of a turret tool post 18 to be held by a collet chuck 10 of the secondary main spindle 8 for its machining. Thus a tool 23 does not interfere with the center 30, and since the workpiece is supported by the center 30 to be machined, even its tip part can be machined, and moreover its no running out in a machining process can simplify the machining of the long workpiece 3. In the case of inverse machining, the center 30 held by the collet chuck 10 of the secondary spindle 8 is moved back by the turret tool post 18 to its waiting position, and the workpiece 3 held on the primary main spindle 4 is transferred to the secondary main spindle 8 to be machined.
