Established in 1950, by the 1980s the Namsun Machinery Works in Korea were offering both CNC machine tools conventional milling machines of the Model Type NSM. These models, also branded as Daewoo (and Dae-Woo) were marketed in the UK by Daewoo Industrial Co. (U.K.) Ltd of Harrow in Middlesex, a wholly-owned subsidiary of Daewoo Heavy Industries Corporation of Korea. CNC lathe by Daewoo Heavy Industries were handled separately in the UK by Mills Marketing Ltd., in Norwich.
Three types of miller were offered: horizontal, vertical and a "multi-function" ram-head with all using - apart from the elements responsible for holding the cutters - the same basic column, knee, motor power and identical rates of normal and rapid table feeds.
Most versatile of the three was the NSM-U, a machine with the same base section and horizontal spindle as the horizontal-only Model NSM-H, but fitted with a Bridgeport-type ram head on the end of an overarm that pivoted on top of the main column. When equipped with the necessary drop bracket on the end of the overarm, this machine could also perform as a conventional horizontal miller.
The Vertical-only miller, the Model NSM-V was, apart from its swivelling vertical head, identical in specification to the NSM-H. Even the nine spindle speeds were not increased (as would have been helpful) but remained at the same rather modest 90 to 14000 r.p.m.
Today, Namsun continues to build, alongside CNC machine tools, a range of conventional, operator-controlled lathes and millers.
