Title (EN) EXCHANGEABLE OPTICAL MODULE FOR A LASER MACHINING MACHINE
(FR) MODULE OPTIQUE INTERCHANGEABLE POUR MACHINE-OUTIL LASER
(DE) AUSTAUSCHBARES OPTIKMODUL FÜR EINE LASERBEARBEITUNGSMASCHINE
Abstract:
(EN) The present invention relates to an optical module (2) for a machine (1) for machining workpieces and/or for producing moulded bodies by location-selective solidification of material powder to form connected regions by means of a focused laser beam. The optical module (2) comprises a housing (8) having means for releasably attaching the optical module (2) to the machine (1). According to the invention, a plurality of optical components (4, 14) are arranged in or on the housing (8) to collimate and focus the laser beam.
(FR) La présente invention concerne un module optique (2) destiné à une machine (1) pour l'usinage de pièces et/ou pour la fabrication de corps façonnés par solidification d’un matériau pulvérulent à des emplacements sélectifs au niveau de zones contiguës au moyen d'un faisceau laser focalisé. Le module optique (2) comprend un boîtier (8) pourvu de moyens permettant de fixer le module optique (2) sur la machine (1) de manière amovible. Selon l'invention, une pluralité de composants optiques (4, 14) servant à collimater et focaliser le faisceau laser sont disposés dans le boîtier (8) ou sur ce dernier.
(DE) Die vorliegende Erfindung betrifft ein Optikmodul (2) für eine Maschine (1) zum Bearbeiten von Werkstücken und/oder zum Herstellen von Formkörpern durch ortsselektives Verfestigen von Werkstoff pulver zu zusammenhängenden Bereichen mittels eines fokussierten Laserstrahls. Das Optikmodul (2) umfasst ein Gehäuse (8) mit Mitteln zum lösbaren Befestigen des Optikmoduls (2) an der Maschine (1). Erfindungsgemäß ist im oder am Gehäuse (8) eine Vielzahl optischer Komponenten (4, 14) zum Kollimieren und Fokussieren des Laserstrahls angeordnet.
