RE: [CAD_CAM_EDM_DRO] Speaking of VFDs

My application is a little unusual. Ideally I want 4000 - 4500 rpm and need
the full support of the spindle to eliminate any vibration, but there is
virtually no cutter load what so ever on the bearings. I am using a 6"
diameter .0625" 160 slotting saw blade to cut 5 lb/cu ft density balsa wood
at 30 ipm. Figure blue styrofoam is 2 lb/cu ft and pine is about 25 lb/cu
ft. I need the rigidity of the spindle to eliminate any flutter in the
blade. Long story, bit if you want to see a little more about what I do with
the wood take a look at my website http://www.IndoorDuration.com

I will keep any eye on e-bay for a speed spindle as that would be handy for
other tasks, but probably not the right solution for this one.

Thanks,
