NOMURA AUTOMATIC NN-16U3 HORIZONTAL MACHINING CENTER

Technical Description

The Nomura Automatic NN-16U3 Horizontal Machining Center is a precision CNC lathe equipped with a single main spindle capable of a maximum turning diameter of 0.630" and turning length up to 7.870". It supports a maximum spindle bar diameter of 0.630" and offers a spindle speed of 10,000 RPM with 3.00 HP power, allowing for efficient machining of small to medium-sized parts. The machine features a slide-type primary tool carrier with a total of 5 turning tools and 4 rotary tools, where the rotary tools operate at up to 6,000 RPM and 1.00 HP, enhancing the versatility for milling and drilling operations. The NN-16U3 provides simultaneous machining with one tool and operates on a 4-axis configuration, including X, Y, and Z travel ranges of 4.740", 8.100", and 8.000" respectively, all with rapid traverse rates of 551 inches per minute. Its capacity and precision make it suitable for complex, multi-axis automatic turning and machining applications where compactness, rigidity, and accuracy are essential. The machine’s design supports stable milling and high metal removal rates in a compact footprint, leveraging precise hand-scraped ways, dovetail slides, and large ball screws for smooth, efficient operation and extended tool life. This balances high-speed spindle performance with versatile tooling for fine, complex machining tasks in automated production environments.
