Miyano BNE-51/65MYY High-Rigidity and Precision CNC Lathes

Sep 5, 2023

The Miyano BNE-51MYY and BNE-65MYY are CNC lathes designed for high-precision and efficient machining. They inherit the reputation of the BNE series for sturdiness and accuracy, while offering several improvements for modern machining needs.

Here are some key features of the Miyano BNE-51/65MYY:

  • High Rigidity and Precision: The machines are built with a strong and stable base to minimize vibration during operation. This ensures high precision machining, even for delicate parts.
  • Double Y-Axis on Upper and Lower Turrets: This innovative feature allows for simultaneous left/right and up/down machining, which can significantly reduce cycle times.
  • Large Machining Capacity: The BNE-51MYY has a maximum machining diameter of 51mm, while the BNE-65MYY boasts a larger 65mm diameter capacity, the highest among Miyano lathes.
  • Improved Tooling Flexibility: Equipped with twin 12-station turrets, these machines provide ample space for a variety of tooling options. This allows for efficient process allocation and reduces limitations caused by machining balance.
  • Enhanced Visibility: The machines feature a completely redesigned cover with a large window, offering excellent visibility of the machining area. This improves operator convenience and safety.
  • New Human Machine Interface (HMI): The BNE-51/65MYY is equipped with a user-friendly HMI that utilizes a touch panel for easy operation. The HMI also integrates seamlessly with the new NC units for improved productivity.
  • Increased Spindle Motor Output: The output of the front and back spindle motors has been increased by up to 1.5 times compared to previous models. This significantly improves cutting capability, especially for challenging materials.
  • Higher Maximum Spindle Speed: The maximum speed has been increased to 5,000 rpm, which is ideal for optimal cutting conditions of small-diameter workpieces.
