The goal: Effectively a 50mm or 2" cutting diameter reduced neck endmill (but with neck very close to 50mm) that would fit on a cat40 tool holder. And no tool diameter larger than 2.5" - because that's the limit of the tool changer.
Would like the "clear of shoulder" reach to be at least 4".
(This is for milling the sides of tall blocks and weldments in a 3-axis machine.)
So something like a 50mm face mill mounted on a very long arbor, I guess, is what I have in mind - but I've not found such.
I've seen 1.25" endmills (the practical limit for a cat40 endmill holder, yes?)
Stiffness rises as the power of diameter (3rd? 4th?) - so a for example 50mm face mill on a 49mm shaft (maybe integral to tool holder) should be much stiffer - especially at 4" effective length.
(Yes, I understand that such a mill, run too aggresively, could easily strain the machine structure - just like a 3" face mill on somewhat shorter arbor can shake a machine badly if the adc or rdc are too large.)
Suggestions for this?
