The MIYANO BNE-51MYY and BNE-65MYY are CNC lathes designed for high-precision and efficient machining. They are part of the BNE series from Citizen Machinery, known for its rigidity and accuracy.
The two models differ in their maximum machining diameter:
- BNE-51MYY: maximum machining diameter of 51 mm
- BNE-65MYY: maximum machining diameter of 65 mm (largest capacity in the Miyano brand)
Here are some of the key features of the MIYANO BNE-51/65MYY:
- High Rigidity and Precision: The machines inherit the rigidity and precision for which the BNE series is known, ensuring high-quality machining results.
- Double Y-Axis and Independent X-Axis: This configuration enables efficient simultaneous left/right and up/down machining, reducing cycle times.
- Improved Superimposed Machining: The design allows for efficient machining of multiple features on a workpiece in a single cycle.
- Large Operator Window: The redesigned cover provides excellent visibility of the machining area.
- New Human Machine Interface (HMI): The HMI features a touch panel for ease of operation and improved productivity.
- Increased Spindle Motor Output: The output of the front and back spindle motors has been increased by 1.2 to 1.5 times compared to previous models, resulting in better cutting capability.
- Increased Maximum Spindle Speed: The maximum speed of 5,000 rpm allows for optimal cutting conditions for small-diameter workpieces.
Here are some additional specifications of the MIYANO BNE-51/65MYY (specifications may vary depending on the model):
- Number of Turrets: 2
- Turret Stations: 12 stations per turret
- Bar Capacity:
- BNE-51MYY: 25 mm
- BNE-65MYY: 32 mm
- Maximum Spindle Speed: 5,000 rpm
- Motor Power:
- BNE-51MYY: 18.5 kW (30min.) / 15 kW (cont.)
- BNE-65MYY: 11 kW (15min.) / 7.5 kW (cont.)
The MIYANO BNE-51/65MYY are ideal for a variety of machining applications, including the production of complex parts for the automotive, aerospace, and medical device industries. With their high rigidity, precision, and advanced features, these machines can help manufacturers improve productivity and efficiency.
