Grinding Aluminum What Type of Finish Expect

[majohnson]

It CGW 60I wheel, it what I could find and only buy 1 piece. Most of the others I would of needed to buy 10 pieces. DOC is .001” with a .02” stepover. It was roughly a second and a-half to cross feed the face. The diamond is sharp. I had taken 2 roughly .0005 passes along with 2 spark out passes. I had to get some mill work done yesterday, so I did not have a chance to do anything else.

I'd get that stepover up way higher on aluminum. Drop the depth of cut to .0003" or in that ballpark. Stay away from a heavy cut when finishing aluminum. Make your light finish grind directly after dressing the wheel. Keep doing the popsicle stick rub to remove any stray grit particles.
