Miyano BNA-42MSY2 Powerful and Efficient Machining Solution

May 1, 2024


The Miyano BNA-42MSY2 is a multi-tasking powerhouse designed for complex machining applications. This machine combines several innovative features to deliver exceptional performance, making it a valuable asset for any machine shop.

Key Features:

Dual Spindle & Single Turret: The BNA-42MSY2 boasts two spindles and a single turret configuration. This unique setup allows for simultaneous machining on the main and sub-spindle, significantly reducing cycle times.

X2 Axis and Y-Axis Capability: The addition of an X2 axis and Y-axis expands the machine's machining capabilities. The X2 axis enables independent machining on the sub-spindle, while the Y-axis provides additional machining freedom for complex parts.

High-Rigidity Spindle: The BNA-42MSY2 features a high-rigidity spindle equipped with angular contact ball bearings and double-row cylindrical roller bearings. This robust design ensures exceptional stability and precision during even the most demanding cutting operations.

Superimposition Control: This innovative control system optimizes machining processes by synchronizing the sub-spindle with the turret. This allows for simultaneous machining on both the main and sub-spindle, dramatically reducing cycle times.

Half-Indexing Turret: The BNA-42MSY2's 8-station turret incorporates a half-indexing mechanism. This ingenious design effectively doubles the number of usable tool positions to 16, providing ample space for a wide variety of tooling.

Specifications:

  • Spindle Motor Power: Spindle 1 motor offers the highest output in the BNA series, enabling powerful cutting.
  • Slideways: High-rigidity scraped slideways ensure exceptional rigidity and damping for improved cutting tool life.
  • Control System: The unique control system boasts a 27% reduction in non-cutting time compared to previous Miyano models, resulting in a 13% overall cycle time reduction.

In Conclusion:

The Miyano BNA-42MSY2 is a versatile and efficient machining solution ideal for complex parts production. Its combination of dual spindles, multi-axis capability, high-rigidity construction, and intelligent control systems make it a compelling choice for manufacturers seeking to boost productivity and precision in their machining operations.
