At Buell Automatics, our commitment to precision and innovation continues with the latest addition to our machining lineup. We’re excited to announce the arrival of our newest powerhouse: the Miyano BNX-51MSY, a multi-tasking CNC machine that’s about to change the game for our customers.

This isn’t just another piece of equipment. With Cincom’s subspindle superimposition technology, the BNX-51MSY operates like two machines in one, delivering unmatched efficiency and capability. Whether you’re in aerospace, medical, defense, or automotive manufacturing, this machine means streamlined workflow for timely delivery, tighter tolerances and more complex parts, all without sacrificing the rock-solid reliability Buell is known for.

What Makes the Miyano BNX-51MSY So Special?

The Miyano BNX-51MSY is a robust multi-axis CNC machine engineered for speed, rigidity, and ultra-precise performance.

Key features include:

• 6-inch 3-jaw hydraulic chuck for powerful and versatile clamping
• Live tooling with Y-axis control for machining complex features in a single setup
• Sub-spindle for simultaneous front and back-end operations
• High-speed performance for reduced cycle times and increased throughput
• Exceptional rigidity and stability for tight-tolerance components
• Maximum machining diameter of 2.0 inches (51mm) for bar-fed operations
• Chuck work diameter up to 6.0 inches (152mm) for larger part applications

The BNX-51MSY also includes an auto-safe tool call, eliminating unnecessary movements to save precious seconds on every cycle. In high-volume production, those seconds add up fast. This machine enables Buell Automatics to take on more challenging geometries and deliver consistent, production-ready parts across multiple industries.

Built for Stability & Long-Lasting Performance

Miyano machines are known for their durability, and the BNX-51MSY is no exception. Its hand-scraped box ways and rigid platform construction keep everything locked in place, even during heavy cutting. The bed design minimizes heat distortion, so parts stay consistent from the first run to the thousandth.

Standard features like a chip conveyor, parts catcher, and parts conveyor mean less manual handling and smoother production flow. That’s less downtime and more uptime, exactly what our customers need.

How This Machine Benefits Our Customers

1. Aerospace: More Complexity, Fewer Setups

Aerospace parts often require intricate features and tight tolerances. With the BNX-51MSY’s ability to perform multiple operations at once, we can reduce setups and improve accuracy on components like:

• Engine fittings needing precise threading and boring
• Flight control shafts with complex milling and turning
• Fuel connectors, housings and brackets

2. Medical: Faster Turnaround Without Compromise

Medical device manufacturers can’t afford delays, but they also can’t accept anything less than perfection. This machine’s independent spindle control allows us to:

• Delivers intricate, high-finish parts for surgical tools and implants
• Minimizes contamination risks through single-setup operations
• Supports precision demands of medical-grade manufacturing

3. Defense & Military: Rugged Parts, Reliable Production

When defense contractors need parts that hold up under extreme conditions, they need a machine that won’t slow them down. The BNX-51MSY’s high rigidity and thermal stability make it ideal for:

• High-strength, mission-critical components with tight tolerances
• Supports applications in weapons systems, communications, and tactical equipment
• High-volume orders where consistency is non-negotiable

4. Automotive: Speed Meets Precision

Automotive suppliers need parts fast, but they also need them right. The BNX-51MSY’s simultaneous operations help us deliver:

• Fuel injector parts with intricate internal features
• Maintains precision on engine, transmission, and EV components
• Ideal for high-volume production with consistent quality

The Buell Advantage: Experience Meets Cutting-Edge Tech

We’ve been machining high-performance parts since 1966. The addition of the Miyano BNX-51MSY marks a new chapter in Buell Automatics’ commitment to excellence, speed, and precision.

Whether you need prototypes, short runs, or full production, we’re ready to put this new capability to work for you. Faster cycles, fewer setups and rock-solid accuracy. That’s what the BNX-51MSY brings to the table.
