Enerpac sets sights on 10m diameter Wind Turbine blades with Milling Machine upgrade

Industrial tools specialist, Enerpac, announces an upgrade to its Wind Power Milling Machine for manufacturing turbine blades, an important stepping stone in its aim of producing next generation milling machines capable of milling blades up to 10m diameter.  Developed specifically for machining the root end of turbine blades, Enerpac Wind Power Milling Machines are a more efficient, accurate, and safer solution than alternative methods such as grinding.

Milling removes any surface imperfection at the flange face between a turbine and blade.  Even the smallest inaccuracies at the root end of a turbine blade can impact a turbine’s structural integrity and performance, resulting in reduced output and increasing operating costs.

The latest Enerpac Milling Machine meets the highest industry standards for tolerance and accuracy for surface finish of 1.6 – 3.2 Ra and flatness tolerance of 0.05 mm. To handle bigger blades, the Milling Machine features an innovative base clamp design to prevent blade damage and distortion, offering self-centring, quick-mount capability for machining blade sizes from 1.8m to 6m Bolt Circle Diameter. Its modular design also allows for quick development to meet the industry’s requirements of larger blade sizes.

Repeatable Accuracy

The Enerpac Milling Machine system consists of machine, base, trolley system, and power unit, with the entire unit easily moved from blade to blade. Enerpac Wind Power Milling Machines have enabled manufacturers to meet the growing need for repeatable accuracy in the production environment.

“Our Wind Power and Milling Machinery technologies have evolved to deliver an optimal combination of precision, productivity, and safety,” says Erik Roos, Director Wind Industry Products & Solutions (ESSAI), Enerpac. “This is why it’s more important than ever to source the right manufacturing equipment from a trusted development partner committed to the Wind Energy market”,

Enerpac Wind Power Milling Machines are designed for machining large metal flanges and can be configured and customised for milling flanges on wind turbine towers and transition pieces.
