The Miyano BNA-S2/DHY3 is a CNC lathe designed for machinists who demand a balance of space efficiency, sophisticated functionality, and top-notch performance. This machine is part of the BNA series, which aims to redefine expectations for bar stock cutting.
Features:
- Space-Saving Design: The BNA-S2/DHY3 boasts a compact footprint that makes it ideal for shops with limited floor space. Despite its size, it delivers high levels of performance, stability, and accuracy – perfect for around-the-clock production.
- Dual Spindle Functionality (S2 Model): The S2 variant features a sub-spindle, which significantly increases versatility. This sub-spindle allows for pick-off and back machining, streamlining your workflow and reducing overall machining times.
- Increased Tooling Capacity: Both the S2 and DHY3 models come equipped with an 8-station main turret with half-indexing capability. This effectively provides 16 stations for tooling, giving you the flexibility to handle a wider range of machining tasks.
- Y-Axis Capability: The main turret (HD1) on the BNA-S2/DHY3 boasts a Y-axis function, further enhancing its versatility. This allows for additional machining operations without the need for tool changes.
- Sub-Spindle Optimization (DHY3 Model): The DHY3 takes things a step further with a 6-station static sub-turret (HD2). This additional turret is ideal for secondary operations on the sub-spindle, maximizing overlap capability and allowing for more simultaneous machining.
- Advanced Control Technology: All BNA models, including the S2/DHY3, come equipped with cutting-edge control technology. This translates to reduced non-cutting times and improved overall productivity. The DHY3 model specifically features the powerful Fanuc 0i-TF control, offering a range of advanced CNC features not available on previous generations.
Specifications:
- Main Spindle Speed: Up to 4,500 rpm (model specific)
- Maximum Bar Capacity: Up to 1 5/8 in (model specific)
- C-Axis Rotation: -30° to +300°
- Y-Axis Travel (HD1): +/- 40 mm
The Miyano BNA-S2/DHY3 is a compelling option for machine shops looking for a space-saving, high-performance solution for bar stock cutting. With its versatile features, advanced capabilities, and user-friendly design, this machine can help you achieve new levels of efficiency and productivity.
