Shinzawa NV-sarja – High Precision Articulated Machine Centre

Shinzawa NV-sarjan articulated machine centres are designed to meet the stringent requirements of modern machining, emphasizing high accuracy, dynamic speed, and structural reliability. The series models, NV-8 and NV-10, utilize digital structural analysis, which has enabled the machine’s center of gravity to be optimized and vibrations minimized even during demanding milling. The machine’s robust “Delta”-shaped column and exceptionally wide frame structure form the basis for a length-to-height ratio of 1:1, which ensures the spindle’s stability across all operating ranges. The high-quality roller type linear guides and pre-tensioned ball screws, mounted on precision coated surfaces, ensure lifelong stability for the movements. An ergonomic design, such as the 85 degree rotating control panel and efficient labyrinth protection against chips, makes the machine not only efficient but also user-friendly and easy to maintain for machine shop daily production.

Performance and Accuracy in a Compact Package

The technical superiority of the NV-series is evident in its versatile equipment, such as the 24-station arm-type tool changer, which has been tested to withstand millions of cycle changes. The spindle is available as either a torque-providing belt-driven version or a direct-driven Direct-Drive version capable of speeds up to 15,000 rpm, which minimizes thermal expansion and vibrations to achieve the best possible surface quality. The six sliding guideways on the X-axis and the wide pitch of the spindles ensure that the table moves smoothly even with the NV-10 model’s 800-ton maximum load. The package is completed by the readiness for fourth axis integration and modern control options, such as Fanuc and Mitsubishi, which make the NV-series a flexible and cost-effective choice for precision mechanics and mould making.
