摘要： A workpiece replacing apparatus delivers a pre-machined workpiece into an intra-machine space inside a machine tool from an extra-machine space outside the machine tool, and delivers a workpiece machined by the machine tool to the extra-machine space from the intra-machine space. The workpiece replacing apparatus includes a secured cover, an arm device, and a movable cover. The secured cover is secured to a securing member of the machine tool. The secured cover defines a partition between the intra-machine space and the extra-machine space. The secured cover is provided with an opening. The arm device delivers the workpieces between the intra-machine space and the extra-machine space through the opening. The movable cover is integral with the arm device or in engagement with the arm device such that the movable cover is operable in conjunction with operation of the arm device. The movable cover closes the opening, with the arm device located in the extra-machine space.

摘要： The invention relates to a method for loading and unloading an internally toothed workpiece or a workpiece that is to be provided with internal toothing into/out of a clamping position, in which the workpiece, which is held by a retaining device, is brought into the clamping position by means of a conveying movement so that said workpiece, when clamped, has internal toothing cut by a gear cutting tool that occupies a cutting chamber and, after cutting, said workpiece, which is held by the retaining device, is returned from the clamping position in a return movement, wherein, prior to cutting, the retaining device is permitted to carry out an evasive movement that is different from the return movement/reverse conveying movement and that frees the cutting chamber, or the cutting chamber is already kept free of the retaining device as soon as the clamping position is reached.

摘要： The present invention is provided with: gear chamfering tools that perform cutting for chamfering a tooth profile ridge section of a gear to be cut; tool holding parts for holding the gear chamfering tools at one end portion thereof; substantially linear movement means which cause substantially linear movement of the other end portion opposed to the one end portion for holding the gear chamfering tools in the tool holding parts; and circular movement means for causing circular movement of an intermediate portion between the one end portion for holding the gear chamfering tools and the other end portion subjected to the substantially linear movement by the substantially linear movement means in the tool holding parts. By combining the substantially linear movement means and the circular movement means, substantially elliptical movement of tip end parts of the gear chamfering tools is achieved.

摘要： A rotation processing machine includes a rotating device supporting a cylindrical workpiece via a rotation support jig; a processing device on which a cutting tool is mounted; and a turning loader that has grippers arranged about a turning central axis and that turns so that the grippers sequentially face the rotating device. The grippers are configured to individually move up and down, and a height position of each gripper is settable to a first height position where the gripper delivers and receives the cylindrical workpiece to and from the rotating device, and a second height position where the gripper delivers and receives the rotation support jig to and from the rotating device. The turning loader turns each of the grippers between an external delivery/reception position where the gripper faces an external transfer stand and an internal delivery/reception position where the gripper faces the rotating device, and is configured to set the gripper to the first or second height position at one of the external delivery/reception position and the internal delivery/reception position, and to turn the gripper to the other delivery/reception position while holding the gripper at the set height position.
