Had a coolant pump go out on a Haas VF-2SS last Friday afternoon

I mean, it was making this weird grinding noise for maybe an hour before it just quit. I had to shut down the job, which was a run of 50 aluminum brackets for a local shop in Dayton. Ended up pulling the pump, cleaning the whole system, and putting in a new one from Grainger, but it killed my whole schedule. Anyone else had a coolant pump fail right at the end of the week?

Used to just run stuff until it died, figured a noise was just part of the job. A pump seizing on a Friday afternoon like yours changed my whole view. Now any weird sound gets an immediate look, even if it means stopping a job early. Losing a weekend to a breakdown costs way more than an hour of lost spindle time. That grinding was its death rattle, and it never gives you a good time to die.

Losing a weekend to a breakdown" is such a perfect way to put it! I never really added up the cost like that before, but you're totally right. That hour of lost time seems like nothing compared to a whole Saturday shot.
