Abstract
PURPOSE:To eliminate the adverse influence of beams past the part to be worked by disposing an object which scatters, absorbs or does others of laser beams into cylindrical glass of which the part to be worked of the inside surface is worked by the laser beam from the outside. CONSTITUTION:Cylindrical glass 1 formed with a conductive film of Cr or the like on the inside surface is supported and rotated by a center 8 secured to the shaft 7 of a pulse motor 12 and a center 9 energized by the spring 17 between a slide 14 and a table 15. A round bar 13 of stainless steel or the like is inserted through a hollow shaft 10. Then, the laser beam of which the axial center of a lens 3 intersects orthogonally with the optical axis of the glass 1 arrives fully at the bar 13. If the surface of the bar 13 is beforehand finished brightly, the greater part of the beam scatters and reflects, and its power density decreases considerably; therefore no damages are given to the conductive film. If the surface of the bar 13 is beforehand blackened, the greater part of the beam is absorbed by the bar 13, and the similar effect is obtained.
