Abstract
A machine tool has a table body and a drive line on a bed. The table body is linearly movable via a guide member having a sliding or rolling guide surface. The drive line has a ball screw or the like, and moves the table body along the guide surface. A pair of guide members are provided at positions in point symmetry about the position of the center of gravity of the table body. Moreover, a pair of drive lines having the ball screws or the like are provided at positions in point symmetry about the position of the center of gravity of the table body. Alternatively, drive line having the ball screw or the like is provided at the position of the center of gravity of the table body.
