A machine tool includes a tool spindle, a tool intermediate device, and a tool storage which includes first tool magazines, a first tool magazine support mechanism, an additional first tool magazine support mechanism, and a tool carrier. The first tool magazine support mechanism includes a first shaft to support at least one of the first tool magazines to be rotatable about a first rotation axis. The additional first tool magazine support mechanism includes an additional first shaft to support at least one of the first tool magazines to be rotatable about an additional first rotation axis. The tool carrier includes a first guide extending along the first and additional first rotation axes, a second guide extending along a line connecting the first and additional first rotation axes, and a lift configured to move along the first guide. The first guide is movable along the second guide.

Machine tool

A control panelhas a display screen. An operator turns a low-thrust pressing keyON in the menu key groupdisplayed on the display screen. In this state, the operator turns an operating dialof a manual pulse generator, thereby causing an encoderto generate pulses. When the encoderoutputs a pulse signal as a command signal, and a servomotoris driven in accordance with the command signal, the tailstock is advanced. With the distal end of a tailstock center contacting a center hole of the workpiece, the operator turns the operating dial, thereby finely adjusting the drive torque of the servomotor. Accordingly, the thrust of the tailstock center is finely adjusted, so that the tailstock center is pressed against the workpiece by a low thrust.
