HI guys,
So I've got the brakes on the new (to me) Mori more-or-less sorted, got the DRO mostly installed, etc. Now it's time to get serious about actually using the damned thing.
And I notice something: the apron Z traverse is sticky.
The bed is in *excellent* shape. I've never seen better.
It's level, no twist, etc.
But as I move it, there's a certain minimum speed that I need to keep above, or it sticks.
Which makes hitting an exact number difficult. It's not stuck, and it's not a location issue, it's just if you stop and try to creep up on a number, it'll stick, and then jump. Seems like it's some sort of sticktion issue. It doesn't jump much, just a thou or two, but that's too much for what I want it for. I'm using Vactra #2 in the apron.
I tried smearing some DTE-Lite on the bed and cranking over that a few times, to see if it was the 'sticky' stuff in the Vactra that was causing the issue. Doesn't seem to be.
I've owned a Cadillac, which is a Taiwanese copy of this style of Mori, and I don't remember that one sticking like this. (Vactra #2.)
My other manual is a 10EE, and that thing is silky smooth. You can roll up on any given tenth and stop right there, with no need to even think about it much. Also using Vactra #2 in the apron.
Comparing most lathes to a 10EE isn't exactly fair, but the Mori is one of the ones I'd expect to be in that class. I know it can do that kind of work, I'm just trying to figure out what the issue is.
Anybody got any thoughts?
Regards,
Brian
