High Speed Machining Center  Manufacturers, Traders, Suppliers

NILES-SIMMONS CNC turn-mill machining centres enable you to carry out economical, flexible, high-precision and user-friendly complete machining of large, rotationally symmetrical workpieces in one clamping. The C-series comprises the sizes N20 MC to N60 MC which can be designed as single or multi-slide machines. Due to the modular construction system, variable processing units can be added and a maximum of flexibility can be offered. With the machines of the C-series you work more efficiently and reduce throughput times. Your advantages at a glance: - Highest flexibility through modular design o Multi-slide concepts o Exchangeable NC axis o (D'Andrea tools, NC boring heads) o Boring bar head change - tailored solutions for workpieces up to 7,500mm length and up to 1,500mm diameter - Complete machining of complex workpieces through process combination: o Turning o Milling/turn milling o Brilling/deep-hole drilling o Gear cutting o Shanking/ roller grooving o Stroke bearing milling o Bottle-neck machining o Double-sided end machining
