..., deburred, and burnished by barrel finishing. In most instances, the main objective is deburring and/or burnishing, with cleaning being an accidental benefit of the treatment. Deburring sometimes is the final barrel operation, but more often it is followed by burnishing to obtain a smoother finish or one...

Highly polished tool surfaces lead to smoother surfaces on the formed parts. Hot working, on the other hand, leaves rough surfaces because oxide...
