PROBLEM TO BE SOLVED: To provide a workpiece machining device facilitating the automatization of workpiece movement, since the workpiece supporting device is used as a loader by synchronously moving a plurality of workpiece supporting devices between a spindle and a tailstock or between first and second spindles while supporting the workpiece by the plurality of the workpiece supporting devices.;SOLUTION: A multitasking workpiece machining device 20 includes: a pair of workpiece support devices 40 and 42 supporting a workpiece; and first and second headstocks 24 and 30 disposed in positions sandwiching the workpiece support devices 40 and 42. The second headstock 30 is disposed so as to move closer to and apart from the first headstock 24. The workpiece support devices 40, 42 respectively include travel drive devices 50, 60 traveling between the first and second headstocks 24 and 30. A numerical control unit 100 controls traveling of the workpiece support devices 40, 42 by synchronously controlling travel drive devices 50, 60.;COPYRIGHT: (C)2008,JPO&INPIT
