Abstract
PURPOSE:To improve the efficiency and quality of cutting by forming a polishing layer having specific Mohs hardness on the raw film of a polishing film and projecting a laser beam thereon. CONSTITUTION:The polishing layer 12 is formed on the raw film 8 of the polishing film by coating a polishing paint contg. a polishing agent having >=5.5 Mohs hardness on a film base body. The laser beam 2 from a laser oscillator 1 is projected through a mirror 3, an optical system 4 and a condenser lens 5 to the raw film 8. An irradiated spot surface 10 generates heat to a locally extremely high temp. state and the film base material is instantaneously removed and cut by liquefaction, gasification and conversion to plasma. Gas such as gaseous N2 is introduced simultaneously from a gas introducing pipe 9 and the base material converted to the plasma is efficiently removed, by which the oxidation reaction thereof is prevented. The efficiency and quality of cutting the raw film 8 are thereby improved.
