| 摘要 |
<p>This invention relates to a machine tool for conducting several types of machining such as drilling, cutting etc., without sacrificing machining accuracy and requiring more than one fitting of a work to a work head to reduce the fitting time of the work. To this end, the work head (4) in this invention has a spindle (16) and a tool head (5) has a spindle (42). A first index section (6) changes the direction of axis of the spindle (42). A second index section (8) indexes the spindle (16) in a first direction (A). A first check section (9) prevents the rotation of the spindle (16) whenever necessary. A second check section (11) prevents the rotation of the spindle (42) whenever necessary. First and second driving sections (7, 10) rotate the spindles (16, 42), respectively. Driving systems (12, 13) move the work head (4) and the tool head (5) relatively and three-dimensionally.</p> |
