PROBLEM TO BE SOLVED: To prevent a work from deforming or buckling in the case of working a large-sized work and to prevent a product and a machine from damaging by providing a remaining frame support means to support one end side of a remaining frame which is supported on a table upper face by being projectingly operated when inclining a work chute to separate a machined work from the remaining frame and to take out the work. SOLUTION: After a plate material supported onto a table upper face is machined at a machining part 2, by inclining a work chute 14, a work separated from a remaining frame is taken out by the work chute 14. When inclining the work chute 14, one end side of the remaining frame supported to the table upper face is supported by remaining frame support devices 22, 22'. By this method, the possibility that the remaining frame losing toughness is subjected to drooping, deforming, buckling, etc., is avoided. Plural remaining frame support devices 22, 22' are provided corresponding to the size of the remaining frame, and a means for retractably operating each of remaining frame support devices 22, 22' is provided.
