I am restoring a Taig CNC mill I am not sure on the age of the mill. I have found a few minor problems so far. 1. Z lead screw bearings were bad 2. the z nut was the old style. These parts are on order for replacement.
I just removed the table and found some interesting patterns on the cross casting see pic’s some of it looks like the start of a center-less grinding pattern???
Has anyone seen this before.
