NOMURA AUTOMATIC NN-16J HORIZONTAL MACHINING CENTER

Technical Description

The Nomura Automatic NN-16J is a high-precision horizontal machining center designed for complex turning operations. It features a main spindle capable of handling a maximum turning diameter and bar diameter of 0.630 inches, with a maximum turning length of 7.870 inches. The main spindle operates at a top speed of 10,000 RPM using a 3.00 HP motor. In addition, it incorporates a sub spindle with identical specifications: 0.630 inches maximum turning diameter, 7.870 inches maximum turning length, 10,000 RPM speed, and 3.00 HP power, enabling simultaneous multi-spindle machining. The machining center includes two tool carriers: a primary slide-type tool carrier supporting up to six turning tools and five rotary tools, and a back spindle carrier with two turning and three rotary tools. Rotary tools feature 1.00 HP power at speeds up to 6,000 RPM. The machine supports up to eight axes for multidimensional machining operations. Axis travels are 4.740 inches (X), 8.100 inches (Y), and 8.000 inches (Z) with rapid traverse rates of 1,300 inches per minute on all three axes, ensuring fast and accurate movements. The compact layout and robust construction facilitate high metal removal rates and stable, precise machining of small to medium-size workpieces, making the NN-16J suitable for intricate and high-volume manufacturing tasks requiring minimal cycle times and extensive tooling capability. Its CNC control and multi-tool capabilities enable flexible and efficient production of detailed components.
