| 20100310335 | WORKING HEAD FOR MACHINE TOOL - 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. | 12-09-2010 |

| 20130322979 | MACHINE TOOL - According to the machine tool according to the present invention, a top-bottom guide is attached to a back surface of a base frame. By being guided by this top-bottom guide, the lifter moves in the top-bottom direction with respect to the base frame. A drive source which drives rotation of a top-bottom feed screw which extends parallel to the top-bottom guide is attached to a back surface of the base frame. This drive source is coupled with a bottom end of the top-bottom feed screw. As a result, compared to when the drive source is coupled with a top end of the top-bottom feed screw, the center of gravity of the machine tool can be set to a lower position. In this way, a machine tool can be increased in stability. | 12-05-2013 |
