Hi, a bit of an expensive option, but if you look at the RS ONline site they have Brushless DC motors (BLDC) and similar that will work on 6v as well as having a controller that allows speed control. Some of these units can easily top 18,000RPM

........machining standards (they say that their discs are ' balanced to an impressive 250th of a gram accuracy', whatever that means) but I'd be happy with 5-10 minutes. ........

It doesn't mean anything, imbalance is measured in gram*mm or any other mass * distance units

.

I think the text on p6 of the linked document is intended to mean that the amount of material removed from the periphery of the disc is correct to within 1/250 gram

[ the disc diameter being quoted as 53mm ]


... and yes, I do realise that the reference radius must be an approximation, dependent upon the depth of the holes.
