PURPOSE:To improve workability and to miniaturize a cutting machine by fixing a metallic thin plate having many holes on the frame body of a laser beam cutting machine. CONSTITUTION:A sheet (supporting body of material to be worked) 28 of metal such as copper, copper alloy, iron, aluminum is fitted and fixed by screws 26 to the frame body 24 of the laser beam cutting machine. Many holes 30 are provided on the surface of this sheet 28 and also, the surface is plated in black and blackening treatment is performed to improve the absorbability of laser beam. In this way, such effects can be obtained that a matter to be worked is not caught because no projection is provided on the edge of the supporting body, the laser beam cutting machine can be miniaturized, the flatness is so excellent that a maintenance means is not required, it is cheap, etc. |
