My old shop foreman swore by flood coolant for everything, I finally ditched it after a job in Austin
I worked at a shop near Austin where the foreman insisted on flood coolant for every aluminum job. Three months ago I was milling 6061 and the coolant kept washing my chips away wrong, causing a finish issue. I tried turning it off and just using a mist system instead, face mill finish came out way better with less cleanup. Has anyone else had better luck dry cutting certain materials?
