Built during the 1960s and 1970s, the Russian-manufactured "CCCP 6N76M" Universal Precision Milling Machine was intended for one-off and small batch production work (the Π was pronounced "P", as in pet). Designed using features borrowed from the established, classic models made by Deckel, Maho and Thiel, etc, it appears to have been a developed copy of the Polish Fabryka Obrabiarek Precyzyinych Model FNC25 (also branded as the "Polamco" and "Avia") ) as well as bearing some similarity in the layout of its head assembly to the Czechoslovakian-built TOS FN40 and FN32. It also appears to have been virtually identical to a machine branded as the "Stankoimport" Type 676Π.
