Thanx for the info, at the time this was happening, there were no fixtures on the 4th, swapping from a 3jaw to a collet, so that probably wasn't the problem. We've been e-stopping it at night, and its been repeating, though on occasion in the past it has not. If I apply the brake at night and shut off the compressor, will the brake still stay applied, a 5C lathe I ran would hold tight overnight with no air pressure, I'm wondering if this will happen with the 4th, I guess I could try and find out. |
