Abstract
The present invention provides a machine tool capable of enhancing approachability to a spindle to improve work efficiency even when it includes a workpiece changer. The present invention includes: a bed; a saddle disposed on the bed to be movable in a forward and backward (Y-axis) direction in a front view of the machine tool; a table disposed on the saddle to be movable in a right and left (X-axis) direction; a column having a shape of a gate bridged over a travel range of the table and fixed on the bed; a spindle head disposed on the column to support a spindle and movable in a vertical (Z-axis) direction; a workpiece changer that turns a workpiece together with a pallet or turns the workpiece independently, for workpiece replacement, between a workpiece standby position set on a back face side of the bed and the table placed at a workpiece change position, the workpiece changer being disposed so as to set the workpiece change position at a position under the column.
