Hi all,
I am working on a custom piece of equipment which involves getting an abrasive grinding wheel into a very tight spot.
The wheel is a cylinder, .55" dia, .15" height. The shank is .092" dia and 1" long.
I need to turn the wheel 1k-4kRPM, so no big deal there.
I'm trying to find a collet, taper, drawbar, etc, that has an OD that is smaller than the wheel so i can get it in place. I'll put some bearings and a small timing pulley on the shank of the tool holder so i can drive it from outside. The torque on the wheel will be negligible.
Ideally, the OD of the largest part of the tool holder would be .4" Not an easy order, I know.
I've found plenty of WW collets that would work well, but nothing to put them into that winds up as a shank.
A pin vise would be perfect, but that's a hand tool and rather inappropriate for this setup indeed.
What's the equivalent of a pin vise that would be good for mounting in a pillow block and driving at 1-4k rpm?
thanks!
