LASER MACHINING EQUIPMENT HAVING A COMMON GAS SOURCE FOR THE LASER OSCILLATOR AND HEAD

摘要

The invention relates to a laser machining equipment including a laser oscillator (1) for generating a laser beam, a laser head (3) through which the laser beam passes, an optical path (2) for conveying the laser beam between the laser oscillator (1) and the laser head (3), and a gas source (9) fluidly connected to the laser head (3) via a main gas pipe (8). In addition, a second pipe (18) fluidly connects said gas source (9) to the laser oscillator (1). The equipment therefore comprises a common gas source for the laser oscillator (1) and head (3). The gas is preferably nitrogen.
