Laser machining system

TL Precision Welding uses Laserdyne Systems' Laserdyne 790 BeamDirector systems for new laser processing work as well as engine refurbishing; the system enables the company to drill difficult-to-machine materials such as Inconel 617, Titanium, and Hastelloy X. A significant amount of engine overhaul calls for the repair and refurbishing of engine components' airflow holes. To position and laser process each of these holes accurately without damaging the part requires the extreme accuracy displayed by the Laserdyne system. The "through-the-lens" viewing feature magnifies clearly all hole features at 45 times magnification. The Automatic Focus Control feature guides the motion system, maintaining critical focus position and following the contour of the part, regardless of slight surface irregularities. All machine axes react to sensing of the part surface, creating unlimited R-axis correction with high speed and sensitivity. A drill-on-the-fly feature delivers laser beam pulses to the part by the stationary laser while the part is rotated. Hole placement is a function of rotational speed and laser pulse frequency. If multiple pulses are required, the software synchronizes the part's movement to the laser pulses, ensuring that multiple pulses are delivered to the exact location required.
