DGM MORI’s LASERTEC 100/160 PowerDrill

Maximum work envelope in a small footprint

Published: Wednesday, August 3, 2022 - 12:00

(DGM MORI: Davis, CA) – DGM MORI introduces the LASERTEC 100/160 PowerDrill for producing turbine components such as guide vanes, blades, and combustors.

Offering efficient laser drilling for aerospace and gas industries, the LASERTEC 100/160 PowerDrill features:
• New moving column concept: constant rigidity and increased positioning accuracy; 0.009 mm according to DIN ISO 10791-4
• Optimized cooling concept: water-cooled motors, linear guides, and ball screws
• Larger working range: X = 1000, Y = 1000, Z = 1000 (LASERTEC 100 PowerDrill); X = 1600, Y = 1000, Z = 1000 (LASERTEC 160 PowerDrill)
• Compact design: space-saving fiber laser (9-23 kW) for reduced footprints (12.7/14.7 m²)
• High dynamics: linear drives for X/Y 90 m/min; 7 m/s²
• Highest flexibility: different laser-head kinematics and table variants
• State-of-the-art features: variable collimation, shoot-through detection, capacitive distance sensors, tool changer, automatic drill position detection

The newly developed LASERTEC 100 PowerDrill and LASERTEC 160 PowerDrill are milestones in the production of cooling air holes in turbine parts for the aerospace and industrial gas turbine (IGT) sector.

The LASERTEC PowerDrill series is a fast and efficient solution for producing cooling air holes in turbine components from the aerospace and industrial gas turbine (IGT) sector. Although the two large LASERTEC PowerDrill models now feature extended traverse paths, DMG MORI has reduced their footprint. A new moving-column concept and a space-saving fiber laser are highlights of these products.

Since limited production space is essential to a company’s manufacturing capacity, the LASERTEC 100/160 PowerDrill is designed for an optimal ratio between installation area and workspace. The modular moving-column concept replaces the LASERTEC 80/130 PowerDrill and achieves constant rigidity in the entire working area. Larger travels in X/Y/Z, up to 1,600 x 1,000 x 1,000 mm with simultaneously reduced footprint (12.7 m² / 14.7 m²), offer maximum flexibility.

Depending on the application, the LASERTEC 100/160 PowerDrill is available with fiber lasers from 9 kW to 23 kW as well as a PowerShape machine version for shaped-hole processing.

The modular axis concept, with swivel axis in the tool and rotary axis in the workpiece (or with swivel rotary axis in the workpiece), offers the right kinematics for every application—especially in bucket and combustor machining. Depending on the application, the machines are available with 9 kW to 23 kW fiber lasers as well as the PowerShape machine version for shaped-hole machining. Linear drives in the X and Y axes also ensure high dynamics with an acceleration of 7 m/s² and rapid traverses of up to 90 m/min.

Accuracy down to 9 µm

To meet the increasingly high accuracy requirements in the target industries, the LASERTEC 100/160 PowerDrill is based on a new moving-column concept with movable X and Y axes. As a result, users benefit from constant rigidity throughout the entire working area. With variable collimation, the laser’s focus size can be changed during processing without manual intervention. The LASERTEC 100/160 PowerDrill can be equipped with different fiber lasers depending on the application. In combination with the newly developed laser control, up to 500 drill holes per second can be produced.

The machine concept is technically designed in particular for laser drilling of components installed in aircraft engines, including turbine guide vanes and rotor blades as well as heat shields, combustion chambers, and similar components. The Lasersoft PowerDrill software, which was developed in-house, supports these tasks with a high level of user-friendliness and easy programming.

The LASERTEC 100/160 PowerDrill’s state-of-the-art components include variable collimation, shot-through detection, and a camera integrated into the laser optics, along with other features such as capacitive distance sensors or an optional tool changer for different processing heads.

CELOS as well as the powerful and user-friendly CNC control SIEMENS 840D ensure reliability and ease of use.

In conjunction with the newly developed laser control system, the LASERTEC 100/160 PowerDrill can produce up to 500 holes per second.
