Re: PM 45 Z axis Linear bearings
looks great! Throw a counterweight or some air shocks on the head and you'll be able to bump up your rapids a bit more.
I'd be interested to see a part machined before and after the upgrade. I know my surface finish improved a bit when I did mine, but I did all 3 axis at once so it's hard to say what was just from the Z axis.
Also...what motor are you running on it? it looks to be fairly substantial and direct drive.

Re: PM 45 Z axis Linear bearings
I had gas shocks on it before the upgrade. They didn't do much so I left them off. I am running a 4025 oz/in stepper on the z. The driver for it is a bit bigger then the 3hp vfd running the spindle.
The surface finishes had improved quite a bit. I haven't really run the machine a whole lot yet. Just to make parts for the ATC I am building for it. I will be making some parts for a vw tdi swap I am starting. machining the fly wheel and adapter plate should be fun.
