Key Point on Machining
For machining of flanges on the outer side of the engine cases, helical machining with a small
diameter radius end mill is effective. ARX end mills deliver an excellent machining
performance when profile machining the outer flanges.
Application Example
Large holes in heat resistant super alloys are machined using helical interpolation with
small diameter radius end mills.
Multifunction
Further use is possible because of reduced tool wear. (after 7 min. machining)
