PURPOSE: To provide a plate machine tool without breaking tools in a drill- tapping time, etc., and without causing a machining defect in a laser beam machining time. CONSTITUTION: A work W is mounted and fixed on a pallet 7 and they are moved and fixed onto a machining table 5. The machining table 5 is moved and positioned, a machining head 33 is positioned along a portal frame and it is machined with the machining head 33. On the other hand, because on the pallet 7, many numbers of unit skids extending to the cross direction of the machining table 5 and being supported with a constant upward force are arranged in the moving direction, when a force more than the constant force is applied, one unit skid is sunk. A skid clamper (skid avoiding device) 107 of the machining position presses down only the unit skid 57 at the machining position. In the case of using a laser beam and drill-tapping combined machine 1, because a brush 125 having the length of the total width of the machining table 5 is installed near the machining position, chips generated on the work W caused by machining can be removed. |
