Does anyone have a suggestion for how fast I should be turning a cast iron lapping disk for polishing a carbide scraper? I built a little spindle to hold the rotor and now need to figure out the pulley size and motor. It looks like the commercial lapping machines for more general polishing turn really slow (less than 100 rpm with a bigger disk than I am working with) which makes me think I only want to turn a very low speeds but I would love to have mode detailed answer than that. I can try to setup a variable speed motor but would rather have the option of a single speed.
thanks
