摘要： A machining head is provided with a turret on which multiple rotating tools are mounted, and this head is configured such that rotation of each of the multiple rotating tools during machining and rotation of the turret are performed by a single motor. A switchable turret rotation transmission mechanism is disposed to be capable of transmitting the rotation of the motor shaft to the turret as the rotation of the turret and releasing the transmission. The rotation of each of the multiple rotating tools during the machining and the rotation of the turret can be performed by the single motor.

摘要： A workpiece change for use in a machine tool that comprises a tool spindle for clamping tools for machining workpieces, comprises two wheels arranged parallel to one another and rotatable about an axis of rotation into at least two prominent angular positions. Two swivel tables for clamping workpieces are arranged between the wheels and are each mounted on the wheels to swivel about a swivel axis which runs parallel to the axis of rotation. In each prominent angular position, one of the swivel tables is located in its working position in which clamped workpieces can be machined with the tools. Both wheels are supported at their rim.

摘要： A rotation table mounted on a machining table of a machine tool includes a clamping mechanism which is driven by air so as to clamp a rotation shaft, and an air purging pressure is applied into a casing so as to prevent a cutting fluid or foreign matter from intruding into the casing of the rotation table. Then, air discharged from the clamping mechanism does not pass through the casing, to which the air purging pressure is applied, and is discharged to the outside of the rotation table through a flow passage.

The press-contact force is caused to act upon the main shaft. The operating fluid supplying mechanism includes a switching portion that selectively supplies the operating fluid. The braking member is formed so that the braking portion causes the press-contact forces that differ from each other.

摘要： A slide disk that is displaceable when the slide disk is bent toward a base section of a frame is provided at a main shaft, and a friction surface that can contact a pressing portion of the slide disk is provided at the base section. The pressing portion of the slide disk normally presses the friction surface to cause the pressing portion of the slide disk to normally press the friction surface, and hence a pressing force for applying to the main shaft a rotational resistance that permits rotation of the main shaft normally acts on the main shaft. Accordingly, even if the position of the center of gravity of a member to be rotated is deviated from a rotation axis of the main shaft, the rotational resistance can be applied to the main shaft.

摘要： In a case where the load is not smaller than the predetermined value, the positioning is not completed even when it is determined that the movable body is moved to the position supposed to be the target position, then the movable body is moved to a retry starting position different from the position supposed to be the target position, subsequently a retry operation is performed for moving the movable body from the retry starting position to the position supposed to be the target position, and consequently the positioning is completed when the load becomes smaller than the predetermined value after the retry operation is performed for a predetermined number of times.

摘要： An angular indexing apparatus for a machine tool includes a rotating shaft, to which a rotationally driven member is secured; a housing, which surrounds the outer periphery of the rotating shaft and which is mounted to and removed from the body of the machine tool; bearings disposed between the housing and the rotating shaft; and driving means, disposed between the housing and the rotating shaft, and rotating the rotating shaft to index an angular position. The driving means includes drive motors, each having a motor rotor and a motor stator concentrically disposed around the rotating shaft in the housing. The drive motors are disposed in series and separated from each other in an axial direction of the rotating shaft. At least one of the housing and the rotating shaft is such that portions thereof are connected to each other so as to be capable of being divided from each other in the axial direction of the rotating shaft. The housing and the rotating shaft are made to correspond to the plurality of drive motors respectively, to connect portions thereof so as to be capable of being divided from each other.
