    Grinding punches to sharpen them, is very common in tool and die maintenance work..

    That device is used to OD grind punches to a specific diameter. The shank of the punch rests on the steel rolls. A pressure roll holds it in place. Turning the crank rotates the punch. It is usually used on a surface grinder and held by the magnetic chuck.
