    摘要: A machine tool has a table body (3) and a drive line on a bed (1). The table body (3) is linearly movable via a guide member (4) having a sliding or rolling guide surface. The drive line has a ball screw (5) or the like, and moves the table body (3) along the guide surface. A pair of the guide members (4) are provided at positions in point symmetry about the position of the center of gravity (G) of the table body (3). Moreover, a pair of the drive lines having the ball screws (5) or the like are provided at positions in point symmetry about the position of the center of gravity (G) of the table body (3). Alternatively, the drive line having the ball screw (5) or the like is provided at the position of the center of gravity (g) of the table body (3). The machine tool can effectively suppress vibrations of a structure (such as the bed) generated during movement of a moving object (such as the table body) relative to the structure by the drive line, thereby shortening the machining time and increasing productivity.
