A machine tool that comprises a fixed bed, a pair of tool posts mounted on the fixed bed on a side closer to an operator and a carriage mounted on each of the tool posts is disclosed. A headstock is provided on a side of the fixed bed farther from the operator so that a workpiece disposed in the headstock is subjected to a cutting process by moving the carriages and the tool posts relative to the workpiece. The machine tool also includes a headstock base having the headstock disposed thereon. The headstock base is structured and arranged so as to be movable between a workpiece machining position where the workpiece can be machined at a position farther from the operator and a workpiece loading and unloading position where the workpiece can be loaded and unloaded at a position closer to the operator.

Machine tool

A machine tool such as an NC lathe having a machine body is disclosed. The machine tool comprises a fixed bed, a machine body having a carriage with a tool post mounted thereon is provided on one side of the fixed bed nearer to an operator, and a headstock for loading a workpiece thereon is provided on another side of the fixed bed farther from the operator. The machine tool also includes a cover having a front wall and a side wall to cover at least a front face and a side wall of the machine body, respectively. The cover is provided so as to externally surround the machine tool, and wherein a portion of the side wall of the cover adjacent the tool post includes a door opening formed therein and a side door for opening and closing the door opening. Thus, the tool replacement work is facilitated and the overall workability of the machine tool can be improved.

A machine tool comprises a fixed bed; a carriage with a tool post mounted thereon is provided on the fixed bed on one side; and a headstock is provided on another side so that the headstock is connected to a headstock base and is movable between a workpiece machining position for machining a workpiece and a workpiece loading/unloading position for loading or unloading a workpiece. The tool also includes a chip collecting space disposed in a cut out portion of the fixed bed adjacent to the workpiece loading/unloading position and a headstock guide unit comprising a guide support mechanism for supporting a front portion of the headstock base by the fixed bed when the headstock base is positioned at the workpiece machining position, and for supporting a rear portion of the headstock base by the fixed bed when the headstock base is positioned at the workpiece loading/unloading position.
