Abstract

PURPOSE:To grind the surface of a depressed area by focusing a laser beam into the powdery grinding compound filled in the depression of a work. CONSTITUTION:A depression 2 in a die 1 or suchlike is filled with powdery grinding compound 3 and the opening of the depression 2 is closed with a cover 4 made of a material which lets a laser light L through. If the laser light L is focused by a lens 5 into the powdery grinding compound 2, the thermal evergy of the laser light L brings the powdery grinding compound into turbulent motions such as jet streaming, floating and vibration so that the abrasive particles collide with and thus grind the inner wall surfaces of the depression.
