British Timken Limited established at their Birmingham works a department expecially equipped for large-scale production of axleboxes of the common-type. The first group of operations for which a special machine was evolved was for the boring and facing of both ends. To obtain maximum concentricity of bores at each end of the housing it was desirable to carry out the operation on a machine in which the housing would rotate. The problem was resolved by the installation of a large double-ended, hollow spindle, boring and facing machine, the bore of the head being such that it would accommodate the largest housing. Considerable economy in machining time resulted by the installation of a Cincinnati duplex horizontal miller with the heads designed to feed vertically thereby eliminating the new setting required for each end of the axlebox. A multi-spindle horizontal drilling machine was installed to improve economy of drilling, specially on split-type designs.
