A machine tool capable of restraining dirt on the footstool and improving setup efficiency. The machine tool includes a machine body having a splash guard surrounding a machining area and a door capable of closing an opening of the splash guard. A footstool is kept mounted on the machine body changeably in place with respect to the machine body. The footstool kept mounted on the machine body is capable of being in a place on an outside of the machine body when the door is closed. The footstool kept mounted on the machine body is capable of being brought to a setup place inside the machining area from the outside of the machine body through the opening when the door is open.

Machine tool

A machine tool comprises a main spindle, a tool post body provided with a first tool mounting part and a second tool mounting part facing each other with a workpiece inbetween in a predetermined facing direction, and a tool post body driving unit for moving the tool post body in at least the facing direction. The tool post body comprises a first tool post unit provided with the first tool mounting part, a second tool post unit provided with a portion of the second tool mounting part with a relative interval with respect to the first tool post unit in the facing direction kept constant, a third tool post unit provided with the remaining portion of the second tool mounting part with a relative interval kept variable; and a relatively-driving unit for moving the third tool post unit in the facing direction with respect to the first tool post unit.

Machine tool provided with tool post

A machine tool includes: a main spindle adapted to be rotatable with a workpiece chucked thereby; a tool spindle capable of moving in directions of three axes perpendicular to each other and capable of pivoting about one of the axes, the axis being perpendicular to the main spindle; an automatic tool changer adapted to detachably attach a first tool and a chucking unit to the tool spindle, the first tool being used for machining the workpiece chucked by the main spindle, the chucking unit being used for chucking the workpiece; and a tool post having a second tool mounted thereon, the second tool being used for machining the workpiece chucked by the chucking unit attached to the tool spindle.

An NC automatic lathe including abase board, a headstock provided with a main spindle and so arranged as to move in a direction of Zaxis, a back attachment provided with a sub spindle which is so arranged as to be opposed to the headstock, the back attachment being so arranged as to move in directions of Zaxis, Xaxis and Yaxis, a guide bush, a first turret tool post arranged at a side of the guide bush so as to move in directions of Xaxis and Yaxis, a second turret tool post arranged at a side of the guide bush so as to move in directions of Zaxis, Xaxis and Yaxis, and a fixed back machining tool unit arranged at a position offset with respect to at least one of the first turret tool post and second turret tool post, to the back attachment in a direction of Z axis, and provided with tool holding portions in at least two rows and two lines in directions of X axis and Y axis.
