How to switch to mill function on 3-1 Grizzly G4015Z

Post by timsch » Mon Nov 07, 2022 9:36 am

Hello all. It's been a while since I switched from lathe to mill on my Grizzly G4015Z, but I have tested it before and it worked fine. I tried again last night but could not get the spindle to turn. I looked in the manual for direction, but only saw what I already knew, which was to set the black hub on the lathe spindle to the IN position. When I did this, the lathe chuck no longer rotated when on, but neither did the drill spindle. I removed the top cover and the drive pulley for the spindle was also not turning. Something was not engaged.

What have I missed here? thanks.

I was hoping to have a suggestion by now. These 3-1 machines are mostly pretty similar, right? I'd dig into the machine to find out how the linkages work, but I don't see a way to remove the housings. There must be a way....

Have you tried to call Grizzly? Their customer support group has a pretty good reputation, I think.

Some have separate mill and lathe motors, but it sounds like yours has a single motor selected by gearing. So I can't really help much.

Yes, single motor with selector gearing.

I was fiddling with it some more and found that something was binding up preventing the selector sleeve from being able to seat into position for mill operation. It seemed to have something to do with the head not being in alignment. When I moved the head slightly more in-line with the lathe axis, I was able to seat the collar. I had the mill head swung slightly out to allow me to machine the part that I set up for. I'll have to dig deeper into why this was a problem, but at least my initial problem is solved.
