backlash
Hi,
I want to try and eliminate the backlash in my servo'ed triac.
the machine is hardly used but has approx 0.003" of back lash in each axis.
Is there an "official" way of tightening this up,or is this the correct working clearence? I was just going to turn one ball nut against its partner to try and do it.

if it's a Fanuc control you can do it in the parameters, I didn't think there was 2 ball nuts

its definatly double nuts all round and its a 1986 model.
Ill check the bearings,but Im 99% sure there ok.
Belts are just right,its the same on every axis.
Anybody got an idea as how I can check the shaft bearings for endfloat?
Isuppose I could put a mag clock on the table/pulley and try and move the table.

End float is usually a bit un predictable - you can get different results depending on the speed you change direction / accel / decel etc..
I think the best way is to get hold of it and push / pull it while watching the clock. A big rubber hammer may also help - make sure servos are on and that you aren't back winding the screw
