My stubborn dry machining habit finally bit me
For years, I skipped using coolant to save time on cleanup. Last month, I had a run of steel parts that kept getting too hot and ruining the finish. A co-worker talked me into trying flood coolant, and now I won't go back. What old habits have you guys changed in your shop?

Watch a guy fight a dry machine for years, then act shocked when a little liquid teamwork fixes everything. It's like watching someone swear they don't need glasses while they're squinting at a menu from three feet away. I guess some of us just need to get burned by a hot, ugly finish before we'll admit the obvious fix.

Yeah, that "hot, ugly finish" line hits home. Been there with some stainless parts that just would not behave. Sometimes you just gotta learn the hard way.

Honestly, that 'give coolant a shot' idea isn't always right. Coolant creates a nasty mess and can mask real issues with your tools. I've had jobs where coolant just washed chips into places they shouldn't be, ruining the finish. With today's tool tech, dry machining works fine for lots of materials like aluminum. The cleanup from coolant often wastes more time than it saves on short runs.
