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.
Finally there is an alternative to ballnose endmills for finishing 3D parts. The combination of finishing tools shaped to provide more cutting surface and a CAM system with the ability to apply them on a five-axis machining center can dramatically reduce finishing cycle times while delivering better surface finishes.
All around the world, companies that machine molds and dies face numerous challenges as well as numerous opportunities. How these companies are responding are influencing the entire metalworking industry.
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.
