The Miyano BNE-51MYY and BNE-65MYY are CNC lathes designed for high-precision and efficient machining of complex parts. They inherit the renowned characteristics of the BNE series, known for their exceptional rigidity and accuracy.
Here's a closer look at the features and specifications of these Miyano models:
Features:
- High Rigidity and Precision: The machines boast a solid construction that minimizes deflection during cutting, ensuring precise dimensional tolerances for your workpieces.
- Twin Y-Axes and Independent X-Axis: This configuration allows for simultaneous left/right and up/down machining, significantly reducing cycle times.
- Improved Superimposed Machining: The design facilitates efficient machining of features on multiple sides of a workpiece in a single chucking, minimizing setup times and improving productivity.
- Large Capacity Twin Turrets: Both BNE-51MYY and BNE-65MYY come equipped with dual 12-station turrets, providing ample tool storage for complex machining operations.
- Excellent Visibility: The redesigned cover features a large window for easy monitoring of the machining process.
- Enhanced User Interface: The new Human Machine Interface (HMI) with a touch panel simplifies operation and improves overall productivity.
