Twin-spindle, matrix depth and length, finish milling machine, Plant No. 2728, made by The Monotype Corporation Ltd., Salfords, Redhill, Surrey, 1963. This machine was used for the finishing of character and depth and overall length adjustment of matrices. It is equipped for the automatic handling of matrices from input to output galleys. It is part of the equipment used in the production system for 0.2 x 0.2-inch Monotype matrices. It is integrated with the bench incorporating electrical and compressed air services, shared with machines Nos. 2294 and 2895.

This machine is one of many used in the process to make a 0.2-inch (0.51cm) or 0.4-inch (1.02cm) matrix. Some of the machines were designed at the Monotype factory in Salfords, Surrey, and other machines were purchased and adapted by Monotype.

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.
