Briney Tooling Systems is well-known as a toolholder manufacturer, but the Bad Axe, Mich.-based company also has a sister facility that performs job shop work. The shop often machines workpiece materials hardened to 50 HRC or harder and manually polishes the parts after machining to achieve the required surface-finish specifications, noted Justin London, sales engineer for Briney.

One such job involved producing punches made of H-13 tool steel hardened to 50 to 55 HRC that had a complex profile on one end. London said each punch required 1 to 2 hours of manual polishing using angle-head pneumatic tools to impart the specified 8-rms finish. In addition, workers had difficulty achieving a consistent surface finish.
