LASER MANUFACTURING INSTALLATION Russian patent published in 1995 - IPC

FIELD: laser working. SUBSTANCE: installation includes a technological laser with a stable semiconfocal resonator, a rotary mirror, a flat mirror and a spherical focusing mirror, a station for securing a part to be worked. The laser beam, had been reflected by the rotary mirror in vertical downwards direction, falls on the flat mirror and after reflection from that flat mirror the laser beam falls onto the spherical mirror to be focused and directed onto the part, being worked. An axis of the focused beam is parallel with an axis of the beam in its path from the rotary mirror until the flat mirror, that is why it is possible to provide combined motion in vertical direction of the flat mirror together with the spherical focusing mirror in order to track a stable focal point on a surface of the part, being worked. A radius of the spherical focusing mirror is being determined according to a formula, given in a description of the invention. EFFECT: enlarged using range of such installation, enhanced accuracy at working parts. 1 cl, 1 dwg
