The Boxford 260VMC as you probably never seen it before!

check the feel of the ballscrews, they are the weak link on that machine. Any notching or play they'll need to be replaced, i did one years ago and used ground 14x5mm pitch screws, also you'll need to sort out homing switches/sensors. Is your spindle R8, 30 int or coventry?

Hi i2i,
The spindle looks very much like the EasyChange itself but without the grove for the balls.
It was a pain to take off! See picture bellow:




Where did you get your ballscrew from? did the new ballnut attach to the existing holders or did you make some new ones?
My X axis has no play at all, the Z got some play between the nut holder and the nut but not between the nut and the screw... How does the nut hold onto the holder? Is it screw in? I don't seems to be able to tight it...
The Y axis got some play.

Something else, I find the spindle a bit stiff. Is it supose to spin freely? I mean if I take the gear on the top of the spindle in my hand and give it a good twist, is it supose to spin a few turns? Cause right not, I can turn it easly, but it won't spin multiple turns if you see what I mean... The cap head screw on the top is it used to load the bearings?
