Europe's largest land-based windmill park opened

Sandvik is leading the development of windmill technology.

This spring, the blades at Northern Europe's largest land-based windmill park started to rotate. The Jädraås facility in Sweden comprises 66 windmills, and there is an option to build 50 more.

The park will have the capacity to meet the annual energy needs of 114,000 households. The windmill park is not only a clean energy source, it also provides many new jobs for local residents.

Productivity demands on gear production

Sandvik Coromant has developed new gear milling tools for the wind industry, among others Vestas, the Danish company that manufactures the wind turbines for the Jädraås wind park.

All gear production is challenging, both when it comes to accuracy and productivity, but even more so for the large gears that are used in wind turbines.

"There's a lot of raw material that needs to be extracted on these large components, so the operation has to be done quickly and efficiently", says David Öhlund, who is part of a team that has developed a new productive gear mill. "Compared to traditional tools, it's possible to use our tools with higher speeds without the tool melting", he continues.
