NOMURA AUTOMATIC NN-20U3 HORIZONTAL MACHINING CENTER

Technical Description

The Nomura Automatic NN-20U3 is a compact Swiss-type CNC horizontal machining center designed for high-precision production of complex components. Featuring a maximum turning diameter of 0.790" (20mm) and machining length of 7.870" (200mm), this machine accommodates bar stock up to 0.790" in diameter. The primary spindle delivers 5 HP at speeds up to 10,000 RPM with a 5.000° index increment, while the secondary spindle matches these specifications for simultaneous dual-spindle operations. The machine is equipped with a slide-type primary tool carrier supporting up to five turning tools and four rotary tools, with a rotary tool motor rated at 1 HP operating at 6,000 RPM. The four-axis configuration includes X, Y, and Z linear axes with rapid traverse rates of 551 ipm across all three axes. The X-axis provides 4.740" travel, while the Y-axis offers 8.090" travel, enabling versatile part geometry and complex machining operations. With one simultaneous cutting tool capability, the NN-20U3 optimizes cycle time and precision through its rigid dovetail structure and horizontal tool post design for efficient chip evacuation. This machine excels at producing intricate medical, aerospace, and electronics components requiring tight tolerances and reduced secondary processing, combining advanced CNC control with Nomura's proven Swiss-type turning technology for efficient, unattended production runs.
