Thrust fitting

The thrust fitting is normally produced in titanium and is located between the wing and the engine. The main challenge is the machining with long overhang tools. ​

​Finishing external circular ramping

Compared to internal circular milling/ramping: The tool centre feed, vf, is increased instead of reduced. The radial depth, ae, becomes much smaller when milling externally, therefore, a higher cutting speed can be used. hex is calculated in the same way as for edging. The programming technique is otherwise very similar to internal milling of holes.

CoroMill®790 with GC1010 with high ramping capability generates straight shoulders with minimal mismatch and very low cusps when passes are repeated.

​Plunge milling

Working with the z-axls is not a first choice when conditions are stable. But conditions are not always stable and plunging is a good solution for weaker set-ups and long overhangs. To maintain a good degree of productivity, it is important to be able to take a reasonable step over. Coromant plunge cutter has maximum step of 22 mm (0.866 in).

​2D profile milling long overhang

The Coromant Capto® modular tool holding system enables tools to be assembled to the required length, while maintaining high stability and smallest run-out. Keep the tooling assembly as rigid and short as possible. Choose the largest possible adaptor diameter/size. Use Coromant Capto adaptors with oversized cutters to avoid reduction adaptors. For small milling cutters, use a tapered adaptor if possible.
