X2 ’Mini Machining Center’ 4th Axis Grinding on hardened shafting.

Yet another job for my hard working 4th axis. Ths video shows end prep on a pair of Hiwin precision ground leadscrews for my new table. Note that the 4th axis prototype is now complete with belt covers, the home sensor has been relocated under the belt cover and there are now pin blocks for locking the spindle for closing/opening collets and other uses. The new table is actually on the job in this video, but it has temporary Thompson rolled ball screws on it. The precision lead screws being end prep
