Re: [CAD_CAM_EDM_DRO] Angular Contact Bearings and Ballscrews question

Hi, another blow out of the water! some of those fancy fixtures are nothing
but very stiff soda grease, washed out after assembly. I mean stiff, so
stiff you can barely wipe it off your hands with a shop-rag! sometimes they
even injection mold with a form to make grease fixtures, and then assembled
on a cold plate it's not a big deal...sometimes they use parafin wax with a
bit of oil added and cast the parts into the fixture/wax..There is a bit
more to the chemistry than i am saying but you get the idea....cul brian f.
