<p>The invention relates to a machine tool comprising feeding system to linearly feed a slide to be fed (5). Each feed gear comprises a first and a second feed mechanisms provided to be in a parallel manner and spaced apart from each other by a specified interval therebetween, wherein each feed mechanism comprises a linear feed-driving means, a feed-moving body which engages with the feed-driving means and moves along the feed-driving means, and a position sensor to detect positions of the feed-moving body along the feed-driving means. Each feed gear further comprises a first and a second support mechanisms respectively connected to each feed-moving body of the first and the second feed mechanisms with rotatably supporting the slide to be fed (5), and a controller (60) for controlling operations of the first and the second feed mechanisms respectively. In addition, at least either of support portions of the first and the second support mechanisms for rotatably supporting the slide to be fed (5) is provided to be movable in such a direction as separating from the other, rotating the slide to be fed (5) according to a difference in moving amount of the feed-moving bodies. Since the slide to be fed (5) is provided to be rotative, even such parts as having complicated surfaces can be easily machined. <IMAGE></p> |
