ABSTRACT:
A machine tool including a bed; a work table horizontally movable on the bed; a column extending from the bed; a spindle head movable on the column; an outer cylinder attached inside the spindle head; a stator of a built-in motor; and a spindle sub-cartridge. The spindle sub-cartridge includes a vertical rotating shaft; a front side bearing having an inner ring fitted to a front end of the rotating shaft and an outer ring fitted to a front housing; a rotor of the built-in motor; a rear side bearing having an inner ring fitted to a rear end of the rotating shaft and an outer ring fitted to a bearing sleeve. The movable range of the spindle head in the vertical direction is longer than a length necessary for inserting the spindle sub-cartridge into the spindle head. The spindle sub-cartridge is can be disassembled and assembled integrally with respect to the spindle head.
