Powerful Cutting – Flexible Welding

The ROFIN Laser MACRO group presents numerous innovations from the areas of laser sources, system peripherals and control technology for cutting, welding and other applications, from the 26 to 30 of October 2010 in Hall 15, Stand E31, at EuroBLECH in Hanover, the leading trade fair for sheet metal working.

Small and Compact – the new Fiber Laser FL 010 C
For the first time, ROFIN presents the FL 010 C, the new compact version of its fiber laser series, which has been specially developed for direct integration into existing machine concepts. With an output power of 1,000 W, the FL 010 C is available as a single-mode laser with a 20 µm fiber and a beam quality of 0.4 mm x mrad or as a multi-mode laser with a 50 µm fiber. Due to its modular and robust design, this laser meets the highest possible industrial demands. This model is also offered with 500 and 750 W output power, which covers the complete range of applications for processing thin materials.

The new Powerhouse – ROFIN’s FL 040
With the ROFIN FL 040, the laser specialist demonstrates the new powerhouse of the FL Series of highly brilliant fiber lasers with an average output power of 4,000 W.

“We are proud to present two new lasers out of our fiber laser product portfolio to a broad audience”, commented Thorsten Frauenpreiß, Managing Director of the ROFIN-SINAR Laser GmbH. „With the Compact Version we are responding the customers request for an integrated laser solution for their various machine concepts. The 4 kW laser demonstrates the extensive development work of our fiber laser series into higher power ranges. With our new fiber lasers and our CO2 Slab lasers we are now able to offer our customers the best laser solutions for all their application demands.“

Fiber lasers of the FL Series offer highest application speeds in thin sheet metals and are easy to integrate into 3D systems as 5-axis machines or robots. They are an ideal addition to traditional CO2 lasers, covering the entire range of sheet metal thicknesses.

The fiber laser wavelength in the range of 1 µm achieves high absorption in many materials. All common solid-state laser applications can be performed using the FL Series laser. With the multi-mode version of the FL laser, fiber optics with diameters of 50 to 600 µm can be used. The single-mode version (max. 1,000 W) produces exceptionally good beam quality, typically in the range of ? 0.4 mm x mrad.

Optional beam switch and energy share modules provide the greatest utilization of the beam source. A single laser can be used in up to four individual work cells. These features support increased cycle times and productivity while minimizing capital equipment costs.

The excellent beam quality also allows the efficient use of “dynamic beam” scanner systems for high-speed positioning as well as the fast and precise application of small geometries at workpieces. This reduces cycle times and increases productivity.

New Standards in Scanner Welding
With the Scanner Welding System (SWS) ROFIN enlarges the comprehensive range of system components by a highly flexible welding solution. The SWS is a fast beam deflection system used for robotically guided multi-spot welding and has been specifically developed for connection to the ROFIN fiber laser series.

The fiber laser is integrated into fully automated welding systems, in combination with a 3-axis scanner and the RobotSyncUnit. Complex shaped 3D components can be welded with the flexibility of the SWS. By coupling all axes of the scanner with those of the robot as a guiding machine, the system commands a total of nine selectable axes. Regardless of whether we are talking about spot-, circular-, wave- or stitching seams - the seam geometry is freely programmable and can therefore be adjusted to strength and component requirements. Through very fast arrival at the next welding position and therewith minimized non-productive time, highest utilization of the welding process can be realized. The real time processing of the geometric data through the control, as well as through the rotating mirrors in the scanner head, enables extremely fast positioning of the laser beam of < 10 ms within the working field. The robot movements and speeds are optimized by complete offline programming of the application. Software functions also calculate the path inaccuracies of the robot so that repeat accuracies in the range of < 0.1 mm are possible.

The RobotSyncUnit is the ideal solution for programming, controlling and monitoring the SWS. As integrated operating and programming interface, the RobotSyncUnit takes care of an optimized interaction of the robot, scanner and laser. The type and supplier of the robot can be freely chosen. Optional offline programming software allows simple import of CAD data.

ROFIN’s Classic for Cutting Applications – the CO2 Slab Laser
From the broad range of high-performance CO2 lasers for cutting applications, ROFIN presents the DC 045. This laser demonstrates its superior capability, especially during the processing of thick sheet metal. The fundamental mode laser quality of the Slab laser and its output power of 4,500 W also enable high-pressure cutting with long focal lengths, which make process stability at high cutting speeds possible, considering their extreme sharpness. For welding applications, DC Series lasers with output power ratings of up to 8,000 W are available.
 
ROFIN’s low-maintenance CO2 Slab lasers are extremely service-friendly thanks to the trend-setting principle. The laser operates with only a few extremely durable components and does not need conventional gas recirculation – leading to a considerable reduction of maintenance and the gas consumption is also minimized. The laser beam that is produced in the resonator is uncoupled by a diamond window without any losses of power or beam quality. The internal water-cooled mirrors are robust and non-wearing reflective optics.

Easy to Integrate – the OEM Version of ROFIN’s SC Family
The “sealed-off“ lasers are ideal tools for light industrial applications such as cutting, drilling and marking. At the EuroBlech, ROFIN presents the OEM 40 iX, the latest model from the successful ROFIN SC Series. With its output power of 400 W and a beam quality of K > 0.8 the sealed-off CO2 laser, based on the industrially proven Slab principle, is suitable for the processing of organic materials, plastics, ceramics, glass and metals.

With its integrated HF power supply and a total weight of 75 kg, the OEM 40 iX is extraordinarily compact, lightweight, and can be integrated exceptionally well into system concepts in combination with scanners or other beam guidance components. Furthermore, the laser distinguishes itself by its high reliability in industrial production. The sealed-off design guarantees a long lifetime of the laser unit.
