We received some cast bronze letters (12″ high) from a customer that they required to be drilled and tapped for mounting, and the surface machined and polished to a high finish.
The surface was surface ground by the auto departments surface grinder that is more commonly used for machining car engine cylinder heads and then the sheet metal department polished the surface to a mirror finish on the polishing spindle to achieve the final bright finish.
The picture shows the letters as an anogram, see if you can work out the name of the ship!
CLUE; its an aircraft carrier and sister ship of the Queen Elizabeth l.
