Fixed Head

Miyano BNE51SY CNC Fixed Head: Twin Spindle, Y-Axis Machining Power

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.
