Balancing service?
(OP)
Anyone know where I could get a 12.75" dia. X .09" thick disk dynamically balanced up to 6000 rpm? The disk has a thru slot and a set of 'counter balance holes' opposite the slot but on a different 'bolt circle. All holes are through. The cad system shows that the theoretical center of mass and center of rotation are the same. Taking into account machining tolerances and consistant material density, I need a backup plan should these disk's (there are 3) need balancing. Two counter rotate on a common 6mm shaft 1/8" apart although I would prefer to balance the disks separately.

What you are asking for could be hard to do. A dynamic balance involves 2 or more correction planes ........ with 0.090" plane seperation, this is a tall order. Also, un balance does increase as a square of the speed, but at 6,000 RPM your part mounted on an arbor may become flexiable, (depending on balance machine bearing span, and other factors),not to mention mounting concerns with the loads that go along with that speed. At any rate, I do know of a place, if you are still looking, you can email me
