PURPOSE:To promote the improvement of workability and productivity reducing a load of the worker by providing a table, fixing a workpiece in machining, and a table, setting up the next workpiece, exchangeably on one straight line further arranging a set position so as to be placed in one part. CONSTITUTION:During machining of a workpiece fixed to a table T on a sliding base board 16, the next workpiece is set and fixed to another table T' on an auxiliary bed 17. After the workpiece, fixed to the table T, is machined, releasing a clamping mechanism B and a positioning mechanism C, the table T is displaced in a direction of the auxiliary bed 17 by a cylinder 24 of a displacing mechanism D and lifted by a cylinder 34 of a conveying mechanism F, and an engaging piece 25 is retracted by releasing it from the stop to a stopper piece 30. Next transfer moving a running bed 33 onto the auxiliary bed 17 by a chain 41, during this transfer, the table T' on the auxiliary bed 17 is transfer fed onto the base board 36 by a feed-in mechanism E, and after the transfer is finished, lowering the table T to be placed on an auxiliary bed 1, the workpiece after machining is removed by retracting a cylinder 27. |
