PSA: The coolant change on my Haas made a way bigger difference than I expected
Honestly, I'd been running the same generic water-soluble coolant for like 8 months on my VF-2SS and just figured surface finish was always going to look a bit hazy. Swapped over to a Blaser product last Tuesday after a buddy at the shop near Portland kept pushing it. The difference in finish quality between the same part run before and after the swap is actually insane, smoother and way less tool wear on the end mills. Has anyone else seen that big of a jump just from changing their coolant brand or mix ratio?

Oh man, tell me about it. I had a similar thing happen about a year ago. I was using this old coolant that had been sitting in a drum for like two years, and the smell was getting pretty bad. Switched to a different brand because my usual supplier was out, and I swear the first part I cut after the change looked like it had been polished. I didn't even change my feeds or speeds, just the coolant. Now I'm paranoid that my old stuff was slowly ruining everything and I just didn't know. It’s like finding out you’ve been using the wrong oil in your car for months.
