as Graham has written, if you use ballscrews (does not matter chinese or not) you should be in a tolerance
less then 0,001 mm per Revolution. so the first step would IMHO be to figure out, where your 'relative big tolerance' is comeing from. backslash (witch is not realy real with ballscrews) lose main bearings for the ballcrew
... and so on. first of all you have to get a preceise move of your axis (over the full range), and then talk about
tolerances.
