Grinder used for 0.2 inch punch production, Plant no. 2439, made by The Monotype Corporation Ltd, Salfords, Redhill, Surrey, England, 1961. Not bench-mounted and no motor attached.

This machine is one of many machines used in the process to make a 0.2-inch (0.51cm) matrix. It was designed and manufactured at the Monotype factory.

There were 82 separate processes needed to transform a designer’s drawing of a letter, figure, punctuation or symbol into a piece of Monotype metal type for printing. A pantograph was used to trace and cut the letter from a copper pattern into a piece of steel called a punch. After being hardened, the punch was driven into a piece of bronze using a crank press to produce a matrix. The finished matrix was ready to go to the Monotype Composition Caster where molten metal was pumped through a mould against the matrix to produce a piece of type.
