Finally got our spindle warm-up routine dialed in and saw a real change

We used to just start the machine and go, but the first part of the day was always a bit off. About three months ago, we began running a 10 minute warm-up program before any production. It has the spindle ramp up through different speeds with light cuts. The difference in size holding on the first piece is huge now, maybe a 0.0002 inch improvement in consistency. It just lets everything expand evenly before we ask for tight tolerances. Has anyone else set up a specific warm-up cycle, and what did you include in yours?

Oh man, that's such a solid point. We do something similar but we also added a slow axis movement routine to get the lube flowing in all the ways before cutting. Found it really helps with those first few positioning moves, not just the spindle heat. It's like letting the whole machine wake up slowly instead of jumping out of bed.

Huh, I actually skip that step on my older machines. @ramirez.betty, I've found that a good warm-up cycle for the spindle does the trick for me, and extra axis movement just adds wear. Keeping it simple seems to work best.

My old Honda Civic taught me this. I stopped doing the full warm up routine and just let it idle for a minute before driving gently. The car lasted 300,000 miles. We overcomplicate maintenance on so many things, from machines to lawn mowers, trying to fix problems that don't even exist yet. That extra step often just gives us a false sense of doing something right while adding real wear. Your spindle warm up is the perfect example of finding the actual key step and ignoring the noise.
