ABSTRACT:
In a vertical machine tool has a main spindle head (13); a main spindle (15) rotatably supported by the main spindle head vertically; and a worktable (7, 9) movable horizontally, a frontmost stroke end position of the worktable (7, 9) relative to the main spindle head (13) is determined in such a way that a rearmost edge portion (7a) of the worktable (7, 9) is dislocated a predetermined set-up stoke Sa away from a central position (C) of the main spindle (15). Therefore, when work is mounted by use of a crane or hoist, it is possible to prevent the hook of the crane from interfering with the main spindle head, thus improving the set-up workability. Further, it is preferable to form a plurality of grooves (25) extending in front and rear direction of the machine tool on an upper surface of the worktable also to improve the set-up workability, without forming a plurality of grooves in the right and left direction of the machine tool.
