Video: What the Heck Is “Dengeling?”
Turns out it is a process that enables a five-axis machine to finish turbine blades after milling. Watch the video.
“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.
Many job shops start in a garage with a used mill and a manual lathe. The owners of this Utah job shop took a different tack. Along the way to a very successful business, they've debunked a bunch of myths commonly held about job shops.
Lockheed Martin’s precision machining of composite skin sections for the F-35 provides part of the reason why this plane saves money for U.S. taxpayers. That machining makes the plane compelling in ways that have led other countries to take up some of the cost. Here is a look at a high-value, highly engineered machining process for the Joint Strike Fighter aircraft.
The right route starts with the workpiece, but there are many other considerations.
