<p>Provided is a laser processing device capable of performing high-precision work at high speed. Respective ends of expandable arms of first and second axes are supported to be turnable within a predetermined range of angle about a pivot in a plane parallel to a surface being worked. A processing head is supported at a point K of connection of the expandable arms of first and second axes. The respective arms comprise a ball screw and a cover having an expandable tube construction, and the processing head is provided with a ball nut which threadedly engages with the ball screw. When the ball screws are rotatingly driven by servomotors, the arms expand and contract to move the processing head. A Z-axis adjusting mechanism is provided between a connection of the processing head with the respective arms and a processing nozzle at a tip end of the processing head. A three-dimensional parallel drive system and a combination of series drive system and parallel drive system may be employed for driving of the processing head.</p> |
