ABSTRACT:
The present invention provides a machine tool capable of reducing residual vibration occurring at the location time, thereby achieving responsiveness to a recent demand for higher acceleration/deceleration speed. The machine tool is configured such that a column3is fixed on a bed2, a spindle head6for supporting a spindle7is disposed on a front face3b′ of the column3to be movable in a Z-axis direction, and a pair of right and left Z-axis ball screws (spindle drive shafts)22for driving the vicinity of the gravity center of the spindle head6is disposed on the front face3b′ of the column3to be symmetrical to each other with respect to a plane that includes an axis C of the spindle head6and is parallel to a Y axis, thereby driving the vicinity of the gravity center of the spindle head6.
