complete conversion kit for AMA25LV

[Fatoftheland]

Thanks gents.
If I buy the ballscrews, is it possible to cut them and turn the ends on my lathe or are they super tough? Would it be easier to get them cut at source like Zapp automation offer. But what length and fittings do I want? I know I need ballscrews, ball nuts. but what goes on the ends bearing and mounting wise?

Well depends on your lathe and your abilty's really. You'll need Collet chuck to hold the screws as 3 or 4 jaw won't be good enough. How hard depends on the screw quality. Often chinese screws are only case hardened and not very deep so can be turned with correct tooling.
Better quality screws are hardened deeper. Often the ends are ground not turned on harder quality screws, I know for sure Zapp grind not turn.

How you fasten the ends will depend on the conversion but in all cases at least one end will be "fixed" and use 2 x angular contact bearings fixed in a ridged housing of some kind to stop the screw floating. Often with mill screws being short then only one end of screw is fastened the "fixed" end and other end is left unsupported.
On longer length screws you would support both ends with bearings but only one end is Fixed and the other bearing free to float in it's housing to allow for expansion.

Really regards length and what exactly is required no one except someone who's done the exact same machine can tell you and even then I wouldn't trust without checking your own machine as castings etc change and often clearences, esp around the ballnuts are tight so best working from your own measurements.
