Abstract

Abstract An apparatus for laser treatment of materials comprises a laser (1), a coordinate table (2) on which a material (3) to be treated is placed, a system (4) for delivery, transformation and focusing of laser radiation, equipped with an outlet barrel (6) and arranged along the path of a laser beam (7). The apparatus also has a numerical control system (8) connected to the laser (1) and the coordinate table (2). The laser radiation delivery, transformation and focusing system (8) comprises a mirror optical unit (9) equipped with a drive (10) for rotation about an axis (16) thereof and connected to the NC system (8). The apparatus is universally applicable, easily adaptable to production conditions. It can be used for laser surface hardening, welding, doping cutting and various similar operations involving workpieces of intricate shapes.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 107 words
An apparatus for laser treatment of materials, comprising a laser (1), a coordinate table (2) on which a material (3) to be treated is placed, a system (4) for delivery, transformation and focusing of laser radiation, equipped with an outlet barrel (6), arranged along the path of a laser beam (7), and provided with a numerical control system (8) connected to the laser (1) and the coordinate table (2), characterized in that the laser radiation delivery, transformation and focusing system (4) comprises a mirror optical unit (9) provided with a drive (10) for rotation about the axis (16) thereof and connected to the numerical control system (8).
Claim 2
Independent Claim 107 words
An apparatus for laser treatment of materials, comprising a laser (1), a coordinate table (2) on which a material (3) to be treated is placed, a system (4) for delivery, transformation and focusing of laser radiation, equipped with an outlet barrel (6), arranged along the path of a laser beam (7), and provided with a numerical control system (8) connected to the laser (1) and the coordinate table (2), characterized in that the laser radiation delivery, transformation and focusing system (4) comprises a mirror optical unit (9) provided with a drive (10) for rotation about the axis (16) thereof and connected to the numerical control system (8).
Claim 3
Dependent Claim 27 words
An apparatus as claimed in claim 1, characterized in that the mirror optical unit (9) is made as a mirror (12) connected with an adjusting device (13).
Claim 4
Independent Claim 29 words
An apparatus as claimed in claims 1 and 2, characterized in that the mirror optical unit (9) is made as a mirror (12) equipped with a scanning device (14).
Claim 5
Dependent Claim 39 words
An apparatus as claimed in claim 1, characterized in that an axis (15) of the mirror (12) of the mirror optical unit (9) is directed at an angle to the axis (16) of rotation of the optical unit (9).
Claim 6
Dependent Claim 76 words
An apparatus as claimed in claim 1, characterized in that the outlet barrel (6) of the system (4) for delivery, transformation and focusing of laser radiation is provided with a mirror (17) set at an angle to the direction of the laser beam (7) and connected with the drive (10) of the mirror optical unit (9) so that the outlet barrel (6) can rotate about an axis coinciding with the axis of the laser beam (7).
