“Dengeln” is a German word meaning sharpening or honing. It’s typically a manual process whereby a hammer and anvil are used to smooth and sharpen the blades of scythes or sickles. Machine tool builder Starrag has developed what it calls its “dengeling” process, which is a more advanced version of this concept. The process enables a five-axis machine to mill and then finish turbine blades in one setup, eliminating secondary polishing, grinding or shot peening operations. Learn more in this article.
