The BNE51SY CNC Fixed Head builds on Miyano’s reputation for high rigidity and precision. This model combines proven performance with advanced features for complex machining tasks.
It features Y-axis for the top turret. The machine layout also allows superimposed machining and 3-tool simultaneous cutting, reducing cycle times and increasing flexibility.
The covers improve accessibility and includes a large viewing window for better visibility. The Fanuc HMI control simplifies setup and operation, helping operators work more efficiently.
An upgraded NC unit, enhanced structural design, and powerful twin-turret layout, the BNE-51SY is built for high-accuracy, high-output production.
