LASER PROCESSING APPARATUS Russian patent published in 1994 - IPC

FIELD: laser processing equipment. SUBSTANCE: apparatus incorporates laser, focusing objective and working table both of them being mounted for relative displacement in three mutually perpendicular directions. Working table is intended for parts being processed to be secured in working zone for rotation relative two mutually perpendicular axes. Working zone of working table is positioned symmetrically relative to one of these axes. Working table of apparatus is provided with additional guide intended for its longitudinal displacement and secured perpendicularly to mentioned axes of rotation, while focusing objective is fixed for movement relative to working zone of table in three mutually perpendicular directions. In the course of processing parts, including large-sized ones, only a portion of part being processed remains in working zone. Due to table rotation round its axis part being processed passes in succession completely through working zone and table in this case may be positioned beyond limits of this zone. EFFECT: reduced overall dimensions of apparatus and wider range of parts capable to be processed. 3 dwg
