Ball Screw Test Ends Lathe work
Posted: Sun Jun 17, 2012 3:56 pm
Thinking of possible ways to machine the ends of my ball screws. They are too hard to turn well in my Myford hobby style lathe, so I will need to aneal the ends of the screws or weld/glue a softer steel to the ends.
Here I have bored a 6mm hole in a piece of m12 threaded rod representing my ball screw. Then I turned down my steel rod at one end to slip inside the bore of the screw. This time I welded them together but I have heard some types of loctite will glue these part together just as well and this means I do not have to expose my screws to the heat of the welder.
As my welded in steel ends are about 18mm in diameter I will be removing plenty of material meaning the OD will become conentric to the rest of the ball screw.
