Abstract

Provided is a highly practical machining system. The machining system is configured to include a base, and multiple machining modules which are detachably disposed on the base to be aligned with one another in a left-right direction. Machining is sequentially performed by the multiple machining modules with respect to a workpiece. At least one of the multiple machining modules is a vertical lathe module. It is possible to configure a compact system in which machining can be performed by a vertical lathe.

a beam moving device which moves the beam in the up-down direction and the front-rear direction in order to move the turret when machining of a workpiece is performed, and

wherein the beam is disposed to deviate to one side and the spindle is disposed to deviate to the other side in the left-right direction individually from a center of the vertical lathe module in the left-right direction.

5. The machining system according to claim 1,

wherein the vertical lathe module includes a housing surrounding a workpiece supported by the spindle and the turret in order to define a machining space in front of the column,

wherein the vertical lathe module includes a tailstock device by which a rotary center at an upper end of a workpiece supported by the spindle is pressed downward,

wherein the tailstock device has (a) a rotation center whose tip portion is pressed against a workpiece, (b) a tailstock which holds the rotation center and is supported by the column to be movable in the up-down direction along the column, and (c) a tailstock moving device which moves the tailstock in the up-down direction,

wherein the housing has a beam opening and a tailstock opening which are each provided on a rear side while the beam opening allows the beam to be inserted through an inside of the housing and the tailstock opening allows the tailstock to enter the inside of the housing, a beam opening movement allowing mechanism which maintains the machining space defined by the housing and allows the beam opening to vertically move in accordance with a vertical movement of the beam, and a tailstock opening movement allowing mechanism which maintains the machining space defined by the housing and allows the tailstock opening to vertically move in accordance with a vertical movement of the tailstock, and

wherein each of the beam opening movement allowing mechanism and the tailstock opening movement allowing mechanism has a frame which defines the opening and is vertically movable, a plurality of cover plates which are respectively disposed above and below the frame, and a telescopic cover plate movement allowing mechanism which allows the plurality of cover plates to move in accordance with a movement of the frame between a state where the plurality of cover plates overlap each other and a state where the plurality of cover plates are disposed to be aligned with one another in the up-down direction.

2. A machining system comprising:
