PARTICULARS have recently been released of the new Wickman-Hollroyd spar-boom horizontal milling machine which is being manufactured by A. C. Wickman Ltd., of Coventry. This tool is made in three forms: as a plain single-spindle machine; as a single-spindle miller with vertical “in-feed” to the cutter; and as a duplex horizontal milling machine. Figs. 1, 2 and 3 show the three types respectively. It will be seen that the three versions are basically the same, each having a substantial bed and a travelling cutter saddle. The following are the principal characteristics for the three types:
