Abstract
A machine tool includes two movable tables on which workpiece is mounted. A base mount has an upper surface provided with at least two machinable regions and workpiece handling regions. A column is supported above the base mount and movable in a first direction, and a spindle head is supported on the column and movable in a second direction perpendicular to the first direction. The spindle head is movable over the machinable regions. The tables are arranged in parallelism and movable in a third direction perpendicular to the first and second directions. Each of the tables is movable between each of the machinable regions and the workpiece handling regions. First, second and third drive means are connected to the column, the spindle head and the tables, respectively. The drive means are also connected to a numerical control unit for numerically controlling the movements of the column, the spindle head and the tables in the first, the second and the third directions respectively.
