Old timer at the shop in Gary told me to run my finish pass at 60% speed back in 2019, wish I'd listened sooner
When I was greener, a guy named Ray who ran a mill for 30 years told me to cut my finish pass speed way down and let the tool do the work. I nodded and then ran it wide open anyway because I thought faster meant more parts, and my surface finish looked like sandpaper for months. Ray passed away two years back, but I still hear him when I'm dialing in a new job. It took me about 3 years and a lot of scrapped parts to figure out he was right all along. Now I run my finish passes slower and my inserts last way longer, plus the parts come out cleaner the first time. Funny how the old guys know stuff we think we're too smart to hear. Anyone else got a piece of advice from a veteran operator that took a while to sink in?
