摘要： PROBLEM TO BE SOLVED: To execute the centering and decentering work of a workpiece by mounting a tool spindle for receiving a drivable tool to rotate the same about a tool spindle axis, on a transverse sliding part, and positioning the tool spindle axis at a specific angle with respect to the X direction. SOLUTION: A workpiece W held in a workpiece spindle 20 is moved to a rotating position limited around a workpiece spindle axis by a numerically control around C axis, and a carrier for a transverse sliding part is numerically controlled by a pivot driving device. A tool spindle 162 is mounted on a transverse sliding part 58 for receiving a drivable tool 166 and the like so that it is moved to a machine frame and rotated about a tool spindle axis 164, around a pivot shaft 90 in parallel with the workpiece spindle axis mounted in a selected section. The tool spindle axis 164 is positioned at an angle less than 45 deg. with respect to the X direction.

摘要： PROBLEM TO BE SOLVED: To change the edge rigidity of a lathe turning tool following to a machining process. SOLUTION: Two hydraulic cylinders 7, 8 are arranged on a sideways middle stand 2 upper/lower symmetrically for the slide axis of a tool rest 1. The contact shafts 9, 10 to which the piston rods 7a, 8a of the hydraulic cylinders 7, 8 are contacted are fixed to the tool rest 1. The lower slide surface 11 is formed in an arc shape around the upper contact shaft 9. Direction selector valves 14, 15 are installed in a hydraulic circuit 12 so as to control respective hydraulic cylinders 7, 8 separately. The edge rigidity of a lathe turning tool 5 is increased by extending the hydraulic cylinders 7, 8 together and clamping the tool rest 1 to the middle stand 2 at upper/lower two places. The edge rigidity is decreased by extending the upper hydraulic cylinder 7, shrinking the lower hydraulic cylinder 8 and supporting the tool rest 1 turnably for the middle stand 2 around the upper contact shaft 9.

摘要： PROBLEM TO BE SOLVED: To provide a cutting work method for securing highly accurate cylindricity (complete round, straight and parallel) for a shaft-shaped workpiece, and a tool rest device in a comb cutter lathe for achieving the method. SOLUTION: This cutting work method cuts a shaft-shaped workpiece 4 rotatably set between a main spindle base 2 and a tail stock 3 by a cutter 6 moved in parallel and orthogonal directions along a rotational center axis. After rough machining, the workpiece 4 is subjected to primary finishing work. The cut state of the cutting quantity of the workpiece 4 cut by the primary finishing work is detected, and the workpiece 4 is cut to reach a target cutting quantity by secondary finishing work according to the cut state of the cutting quantity of the primary finishing work. Thus, the orthogonal moving amount of the cutter 6 with respect to the workpiece 4 is corrected, and then secondary finishing work is carried out.

摘要： PROBLEM TO BE SOLVED: To provide a machine tool which can finish, by cutting work, the outer surface of a disc part of an aluminum wheel up to a mirror-surface. SOLUTION: In a machine tool for cutting an aluminum wheel, comprising a bed 2, a spindle stock 3 having a spindle 4 and a main bearing rotatably journaling the spindle 4, a drive motor for rotating the spindle 4 about the center of the latter, a movable carriage 6 sliding along a slide guide surface on the bed 2, hydraulically operating part 5, and a hydraulic unit 12 for supplying hydraulic pressure to the hydraulically operating part 5, the spindle 4 is concentric with the shaft of the drive motor, and a cylindrical roller bearing having a fourth grade of precision regulated in JIS B 1514-1086 and JIS B 1533-1993, is used as the main bearing. With this arrangement, deflection, vibration, rotational unevenness and the like of the spindle 4 can be effectively restrained, and the system including the spindle 4 can have a high degree of rigidity. With this arrangement, it is possible to effectively prevent a surface to be worked from being roughened, thereby making it possible to finish a surface to be worked of an aluminum wheel up to a mirror surface.
