The NILES-SIMMONS C-Series consists of modular CNC turning and milling centers of sizes N 30 MC, N 40 MC and N50 MC for complete machining processes of large rotationally symmetrical workpieces. Single- and multislide units can be chosen as the basis of the machine. Thanks to the modular system, the basic unit can be supplemented with a variety of different accessories: a universal turning-boring-milling head, an additional milling unit or a turning and boring slide rest for heavy-duty cutting tool disc revolver are just a few examples of the outstanding flexibility of the NILES-SIMMONS C-series.
