I cannot imagine what you are doing to cause this problem from your
information supplied, but it is highly unusual. Please describe what you are
doing and how.

I have a Sherline vertical mill (the 5000 series) and I keep having a
problem with my aluminum workpiece pulling loose from the mill vise.
I have NEVER had very good luck getting the Sherline mill vise to hold
aluminum terribly well. Is this a deficiency of their mill vise?
Would a different mill vise solve the problem? Is it possible that .
010" cuts are too much?
