    Yes?

    Ok, never done a NV5000, in fact, never changed any guides on those. Done others though. Make a fixture to bolt the head to the table, get all covers off, then clamp down to table, unbolt ballscrew, then guide packs. Move Y axis away enough to get guides out. This way is pretty simple, shouldn't even have to disconnect any cables.

    turned out to be pretty simple. i called Ellison technologies down for help with this, when they got here they didnt have a specific procedure for the replacement of the Z-axis linear guides. we ended up doing it how i was originally thinking i would do it. first get all the covers removed and paneling out of your way. i machined an aluminum block, drilled and tapped for a 5/8"-11 bolt. we removed all the bolts from the guides except the top and bottom, loosened the ballscrew nut, then put the block with the bolt behind the head and give it a turn. this pulls the head away just enough to remove the guide. one at a time of course. remove the last 2 bolts and slide the guide out throught the top. the right side is the master and needs to be done first. there is set screws on the side that push the pad of the linear guide up against the head. this is what squares everything. after completing the job Z needs to be checked for squareness to the table. this is adjusted by the set screws on the master rail. hardest part was getting in to clean and stone the mating surfaces, all said and done i think its easier to replace the Z guides than Y. hope this helps someone.

    Re: Mori NV5000 Z-axis linear guides

    Hello all, just stumbled upon this thread looking for information on an NV5000 I'm working on. It appears there isn't any active oiling or any way to grease the linear bearings. Is this a sealed for life system? Thanks!
