LASER COMPLEX FOR PROCESSING LARGE-SIZE OBJECTS Russian patent published in 1997 - IPC

FIELD: mechanical engineering; laser processing of different articles. SUBSTANCE: two cross- members 5 with vertical manipulators 6 are moved along longitudinal guides 3 in complex. First rotary mirror 8 is installed in center of longitudinal guide 4 which is nearest to laser. Mirror is provided with 90-degree automatic turning, mechanism to deliver laser beams in turn to second rotary mirrors 9 and 10 installed on crossmembers 5. Maximum length of optical path is decreased so by half the length of processed object. As a result, difference in diameters of laser beam in nearest and farthest zones of treatment is decreased which increases stability of treatment parameters and, consequently, improves quality of treatment. EFFECT: improved quality. 3 cl, 3 dwg
