Whenever I mill aluminum, the chips to want to stick to the v-wheels. I guess it must be a static-charge thing, perhaps from the wheels moving over the rubber belts, I don’t know. I had been using a toothbrush to clean the chips from the wheels and tracks every 10 minutes or so while cutting. But today I found a better way.
I rubbed down all the wheels belts and tracks with a dryer sheet, the ones that are intended to reduce static cling in the laundry. It helped, a lot! The attraction between v-wheels and chips seems to be broken, at least for now.
