摘要： A machining head for a machine tool includes a spindle unit having a spindle to which a tool is attachable and a support head component. The support head component includes an index mechanism that rotates the spindle unit in order to index an angular position of the spindle unit. The support head component further includes first and second support segments containing respective support shafts disposed opposite to each other across the spindle unit such that shaft centers of the support shafts are aligned with the axis line. Each of the first and second support segments has a housing having a bearing member fixed thereto, the bearing member rotatably supporting the corresponding support shaft through a bearing. The support shaft in each support segment is supported by the corresponding bearing member in a manner such that the support shaft becomes movable together with the bearing member in an axial direction of the support shaft by releasing a fixed state between the support shaft and spindle unit and the fixed state between the bearing member and corresponding housing.

摘要： In a tilting table indexing device driven by a direct-drive motor, a tilting table is prevented from rotating beyond an allowable rotation range when power is shut off in an emergency, such as power outage, and thus a breakage accident of, for example, a tool or a workpiece is reliably prevented from occurring. In a tilting table indexing device (1), in which a rotary member (3) such as a table (4) is rotated within a predetermined normal rotation angle range by a direct-drive motor (9) to tilt the table (4) and in which the tilted table (4) is held by activation of a holding mechanism (10), an elastically displaceable member (11) having a pressure receiving surface (12) is provided at one of the rotary member (3) and a frame (6) of the tilting table indexing device (1), and an engaging portion (13) capable of contacting the pressure receiving surface (12) is provided at the other of the rotary member (3) and the frame (6). When the rotary shaft (5) rotates beyond the normal rotation angle range because of free rotation of the rotary member (3) in an emergency, the elastically displaceable member (11) absorbs the kinetic energy of the rotary member (3) and stops the rotary member (3) before a danger angle range.
