LASER MACHINE, LASER MACHINE AND LASER BEAM ALIGNMENT DETECTION TOOL ASSEMBLY, ALIGNMENT AND CALIBRATION METHOD

摘要

The present application relates to a laser machine (1) for material removal of the Laser Engraving CNC Machine type, comprising: at least one movement axis (X, Y, Z) controlled by a numerical control unit, at least one emission terminal (3) associated with a laser emitter (2), wherein said emission terminal (3) is adapted to emit a laser beam, and wherein said emission terminal (3) defines an optical beam axis along which said laser beam is propagated, an operating unit (22) having an operating unit housing, wherein said at least one emission terminal (3) is accommodated in said operating unit housing, a galvanometric laser head comprising a first galvanometric mirror and a second galvanometric mirror, wherein a laser head frame has a laser head inlet opening and a laser head outlet opening, at least a first rotation joint (11), wherein said at least one first rotation joint (11) is a numerical control rotation joint and defines a first laser machine rotation axis (B), wherein said at least one first rotation joint (11) is configured to rotate said galvanometric head about said first laser machine rotation axis (B) at least between a first angular head position and a second angular head position; wherein said optical beam axis extends from said emission terminal (3) to at least said laser head outlet opening, and wherein said at least one first rotation joint (11) is arranged along said optical beam axis downstream of said emission terminal (3) so as to rotate said at least one galvanometric scanner with respect to said emission terminal (3) about said first laser machine rotation axis (B). Said laser machine further comprises optical axis alignment means configured to move said laser beam along at least two beam translation axes that are incident with respect to said laser beam and about at least one beam rotation axis that is incident with respect to said laser beam.
