We sometimes encounter machine shops that have developed a neat solution for their own machining challenge and would then like to turn it into a product line. KME CNC is such a shop. The challenge of holding tight tolerances for its billet RC helicopter engine components drove the company to develop the innovative fifth-axis tombstone device shown above to complete multiple parts on an HMC in one setup. Read this story to learn more.
The video that accompanies the story demonstrates that the tombstone’s indexers are powerful enough to perform turn-milling operations. It also shows how independent control of the indexers minimizes lag time when moving from one indexer to another.

On the other hand, this video shows the maneuvers that can be performed with an RC helicopter powered by a KME engine.
