I got a new Cab King last week. First 6 wheels are great, highly aggressive and do the job well. I am having trouble with the 8k and the 14k wheels though. No issue with the 50k. The 8 and 14ks scratch the hell out of my rocks after I finish them from the prior 3k wheel. I thought it might be a break in period so I ran a rock I didn't care about for about a half hour on them and only got a finely scratched up rock as a result. Is this normal for cab king wheels at this level? I had to drop the rock back to the 280 soft wheel briefly and start over to get the scratches out. Any suggestions?
I finished up some others and just skipped those two wheels and went straight to 50k and that works for the time being but I hate to just not use the wheels I paid for.

Break in diamond wheels in sequence. Sometimes you don't see the scratches until later and need to go back to earlier wheels. That big of a skip in wheels to the 50000 will eventually wear prematurely. Probably working now due to new aggressive 50000 wheel. All this or you got bad wheels.

You can get a dressing a stone. Kingsley north set me one one time when I had ordered five diamond belts.

The guy I bought them through say to try working a harder stone to work them in and if that fails, send them back for replacement.

If you ever get a cross contaminated wheel this will happen. I will use either a rough surfaced stone or a block of hardwood on the affected wheel. Then go back to a piece needing that grit and see if the scratching stops. After I had this happen I clean my tray and hood before changing to the next wheels. This does cause me to work more in batches however.
