DMG Mori LASERTEC 100 PowerDrill

The DMG Mori LASERTEC 100 PowerDrill scales up the laser drilling concept to handle larger aerospace and power generation components that will not fit on the LASERTEC 50. With X/Y/Z travels of 1000 x 600 x 500 mm (39.4 x 23.6 x 19.7 in), the machine accommodates full-size combustion liners, large turbine cases, and multi-vane nozzle guide vane assemblies.

The 5-axis configuration adds a B-axis tilt of +/-120 degrees and 360-degree continuous C-axis rotation, providing compound-angle access for holes drilled at 15 to 45 degrees relative to the surface normal -- the typical range for film cooling holes on turbine hardware. Positioning accuracy is 8 micrometers with repeatability of 5 micrometers across the full travel envelope.

The fiber laser system delivers up to 4 kW of average power with peak powers reaching 30 kW in pulsed mode, a significant step up from the LASERTEC 50. This extra power matters for drilling thicker sections and coated components where the laser must penetrate ceramic thermal barrier coatings up to 500 micrometers thick plus 3-5 mm of superalloy substrate.

Hole diameter capability runs from 0.3 mm to 5.0 mm (0.012 to 0.197 in). The larger range accommodates dilution holes and impingement cooling holes in addition to standard film cooling holes. Percussion, trepanning, and helical drilling strategies are all available through the CELOS drilling cycle library.

The machine handles workpieces up to 500 kg (1,102 lb), covering even the heaviest turbine cases and combustion hardware. An optional rotary table adds continuous indexing for cylindrical components. Pricing typically falls in the 00,000 to ,200,000 range.
