Hi partners,

I have a UFO planetary machine to do islands and countertops. Quite often I have problems when I get up to 800, 1500(1800), 3000 grit on some soft marbles and super white quartzite.
Major scratching occurs and I need to go back down to 220 and start over.
I’ve tried re-setting the diamonds on the back of a piece of granite and buying new diamonds. Eventually it gets to the point where this keeps occurring.
Anybody else had this issue and was able to resolve?

Thank you,
Chris Santospago
