turbine blade grinding performance

Blade Grinding’s Need For Speed Modern Machine

Blade performance and longevity could suffer. Some years ago, a European consortium—AGNETA—set out to develop an alternate method for grinding turbine blades and vane segments made from nickel alloys and other materials such as titanium aluminides. This consortium was comprised of grinding equipment companies and turbine engine manufacturers.
