Heard a guy at the shop say he runs his coolant at 8% for aluminum, not 10%
I was cleaning up around the old VF-2 yesterday and overheard one of the senior guys telling a new hire. He said for the 6061 parts we run, 8% gives better finish and less sticky residue on the parts. I tried it this morning on a small run of brackets and the parts came out cleaner, less gummy. Anyone else tweak their mix for different materials?
