Bespoke CNC

It depends how much money you want to spend.

Due to the resonance/flex issues, I'd say a normal 4th axis isn't going to be much use, however a tilting table would be, as it would allow for faster maching. As instead of the existing method whereby a radius cutter works side to side the length of the prop, with a tilting table, a larger flat sided cutter can make several passes from root to top to provide a smoother profile. However, it will add alot of cost, and complexity to the machine.


I'm often surprised at the lack of companies offering bespoke machine building, but then there is the issue of who becomes liable when things don't work as intended, which means such companies would probably start charging an unaffordable premium to allow for having to redo things when they don't quite work as initially planned.

Yes seeing how long it is i would agree the tilting table idea which as you say can cut down the machining time which was my thinking.

But wow the cost factor of a 2.5 Mtr tilting table, maybe its all you need to add to a standard machine.
