Vibration during slots milling. Making part more rigid by some kind of putty paste ?

kocykowaty · Mar 20, 2020

Morning.

I have a part, thin walled one, prone to any distortion. It's a big case made of inconel.
I turn deep groove and then mill it into multiple hooks.

The question is. Is there any material in a form of liguid (or anything else) that becomes solid, which I could pour into groove and make it more stiff for milling ?

Something that would get solid fast (30min/1hour).
Something similar to 3M's putty paste:

3M™ ESPE™ Express™ STD VPS Impression Material Refill, 7312

Machinable wax is what I use.

I know there are puttys and wax and such but I can't think of any right now.
But back when I was on a lathe with a boring bar hanging out too far I would tape thin strips of rubber to it to dampen the vibration.

Look for diamond dopping wax, which is actually meltable shellac. I use it for fixturing small odd shaped parts. It can be remelted and most of it reused.

PS: Even better than rubber is a rubber "sand bag" filled with fine lead shot.
