APPARATUS FOR MULTIBEAM LASER WORKING Russian patent published in 1994 - IPC

FIELD: machine engineering. SUBSTANCE: apparatus has a laser, a control system, a mechanical system with a carriage and a traverse bar, rotary mirrors, working heads, a working table, a modulator-divider, including rotation drive, mirror discs with openings, mounted on a common rotation axle. The apparatus also has stationary mirrors, arranged normally relative to the discs, one mirror between each pair of the adjacent discs. The openings of the discs are spaced by the same distance from the rotation axis; that allows to provide symmetrical spatial distribution of irradiation energy relative to centers of the openings, being formed on all parts and to enhance quality of the openings, being formed. EFFECT: enhanced quality of openings with simultaneous drilling of the single-type blanks. 1 cl, 1 dwg
