Watched a guy at a trade show in Chicago run a brand new machine with no coolants
Stopped by the big manufacturing expo last Friday and saw this operator running a fresh 5-axis mill, but he had zero coolant in the lines. He was just letting the chips fly dry, which can wreck your cutters real fast. I asked him about it and he said his supervisor told him to skip the coolant until the machine 'loosened up.' Took about 20 minutes before the spindle started sounding like a bag of rocks. Has anyone else seen shops try some wild shortcuts like this to save time or keep the floor clean?

That supervisor must have been real confident in that machine's warranty. Twenty minutes of dry running before the spindle sounds like gravel is actually a pretty good record, most cutters I've seen would have given up sooner than that. Sounds like they wanted the floor spotless for the show, which is a great way to save a little sweeping time and blow a couple grand on tooling. I bet that machine is still sitting there with a "do not operate" tag on it today. Tell me they at least had extra end mills on hand, because they were definitely gonna need them.
