BMW places large Trumpf disk laser order

The German laser company Trumpf is to supply the car maker BMW with 14 of its “TruDisk” lasers, with shipments scheduled to begin this October.

Trumpf says that the laser units will feature a variety of beam characteristics to meet a range of different applications including conventional welding and robot-assisted remote machining. the company told optics.org that BMW will be using 4 kW units in a networked configuration that helps to cut manufacturing downtime.

The BMW order underlines the relative strength of the automotive market’s demand for new lasers, even at a time when wider macroeconomic trends are putting many other markets under pressure.

Last week, both Rofin-Sinar and IPG Photonics said that automotive manufacturing remained a strong driver for lasers, with Rofin reporting rapid year-over-year growth for the application and IPG suggesting that the industry’s adoption of new materials would see that trend accelerate.

Examples of that include the use of high-strength steels and aluminum in cars, although there is a divergence of opinion on whether lasers will ultimately be the tools of choice for working with aluminum, because of difficulties with welding the metal.

Last month, Trumpf announced that it had made record sales of €2.33 billion in its fiscal year 2011/2012, which ended on June 30, up 15% from the prior year and eclipsing the company’s previous best-ever result from the pre-recession year of 2007/8.

Although the family-owned Ditzingen company is yet to reveal how much of that increase was due to higher laser sales specifically, the strong results posted by publicly-listed rivals such as IPG and Rofin over a similar period suggest that lasers did account for much of the growth.

Trumpf’s president Nicola Leibinger-Kammüller added that orders and profits had also risen on the previous year, and that the company had created more than 1000 jobs during the 2011/2012 period, bringing its total employee count to 9600. the company is due to present its full results for the year on October 18.

More power for EuroBlech show Trumpf also says that it will show off a range of industrial laser innovations at the forthcoming EuroBlech trade show for the sheet metalworking industry, which will take place in Hanover in late October. And although the auto industry appears to be moving increasingly towards 1 µm laser tools in the form of disk and fiber designs, Trumpf still sees plenty of scope for innovation with CO2 lasers.

The company says that it will demonstrate cutting of stainless steel up to 50 mm thick with its TruFlow 8000, an 8 kW CO2 laser, and improved edge quality for two-dimensional laser cutting with its “BrightLine” option for 20-25 mm-thick stainless steel.

“The higher laser output is intended especially for shops that work stainless steel and aluminum,” Trumpf said. “A machine with an 8 kW laser can slice through aluminum sheets up to 25 mm thick. that is 5 mm more than the same machine with 6 kW of laser power.”

The company adds that for materials thicker than 10 mm the new lasers will be up to 33% faster for fusion cutting applications.
