NILES-SIMMONS N20 MC CNC LATHES

Technical Description

This 4-axis CNC lathe mill is engineered for high-precision machining of complex workpieces, combining turning and milling capabilities in a single platform. The machine delivers robust performance with a 45.6 hp main drive, enabling efficient material removal across a wide range of metals and composites. The spindle achieves a maximum speed of 3,800 RPM, supporting both high-speed finishing and heavy-duty cutting operations. Designed with a 25.6-inch swing, it accommodates large-diameter parts, making it suitable for demanding industrial applications. The inclusion of a tailstock ensures secure workpiece support during extended turning operations, enhancing accuracy and rigidity. Machine control is managed by the advanced SINUMERIK 840D sl CNC system, providing intuitive programming, seamless integration with CAD/CAM software, and precise axis interpolation for simultaneous 4-axis movements. The system supports complex contouring, drilling, and milling operations, allowing for the production of intricate geometries with tight tolerances. The machine’s rigid construction, combined with high-quality linear guides and ball screws, ensures long-term reliability and repeatability. Integrated coolant management and chip removal systems maintain a clean working environment and prolong tool life. With its versatile capabilities, this 4-axis CNC lathe mill is ideal for prototyping, small-batch production, and high-mix manufacturing environments where precision, flexibility, and efficiency are paramount.
