Abstract:
A machine tool including: a table disposed on a saddle movable along an X-axis; a pair of linear motors that moves the table along a Y-axis; position detectors that detect a first position and a second position of the table on the Y-axis; a pair of guide rails attached to the saddle; and four bearings engaged with the pair of guide rails, is provided. The machine tool includes a connecting unit connecting the table to the four bearings such that the table is rotatable relative to the four bearings, and a control unit that controls the pair of linear motors on the basis of the first and second positions.
