NOMURA AUTOMATIC NN-25YB HORIZONTAL MACHINING CENTER

Technical Description

The NOMURA AUTOMATIC NN-25YB is a high-precision, 8-axis horizontal CNC Swiss-type machining center designed for complex, small-diameter turning and milling operations. It features a main spindle with a maximum turning diameter and bar capacity of 1.000", capable of machining lengths up to 7.870", and a sub-spindle with identical turning diameter and length specifications. Both main and sub-spindles operate at speeds up to 10,000 RPM, with the main spindle delivering 5 HP and the sub-spindle 3 HP, ensuring robust performance for demanding applications. The machine is equipped with two slide-type tool carriers: the primary carrier supports up to 6 turning tools and 7 rotary tools (2 HP, 6,000 RPM), while the secondary carrier accommodates 2 turning and 2 rotary tools. This configuration enables versatile tooling setups for simultaneous turning, drilling, milling, and tapping operations. The NN-25YB offers X-axis travel of 4.740", Y-axis travel of 8.100", and Z-axis travel of 7.870", with rapid traverse rates of 551 ipm on all axes for efficient cycle times. With a maximum of one simultaneous cutting tool in standard configuration, the machine ensures precise control and accuracy. Its advanced design supports a wide range of precision machining tasks, making it ideal for industries requiring high repeatability and tight tolerances in small-part production.
