Spindle lube leak almost wrecked my machine
I noticed a small oil puddle under my CNC spindle yesterday. It seemed minor, so I kept running jobs. Soon after, the spindle made a weird grinding sound that got louder fast. I hit the stop button before anything broke. This could have led to a full spindle failure if ignored. Now I'm checking all my machines for similar leaks. Has anyone else dealt with lube lines coming loose over time?
