Claims

[Claims for Utility Model Registration] A table for placing and supporting a workpiece,
In a machine tool equipped with a table that is movable back and forth between a machining position where a workpiece supported on the table is cut and a workpiece set position located in front of the machining position, the table is moved forward to the workpiece set position. Pressing means for centering is placed on both the left and right sides of the table, and includes a presser that faces the sides of the workpiece on the table, and a hydraulic cylinder oriented in the left-right direction that pushes the presser toward the workpiece. A workpiece for a machine tool, characterized in that it is provided with a hydraulic pressure supply means that is symmetrically and independently provided and supplies hydraulic pressure of equal pressure and equal flow rate to the left and right hydraulic cylinders in order to operate the left and right hydraulic cylinders symmetrically and synchronously. centering device.
