Miyano BNA-S2/DHY3 Setting the Standard for Compact, High-Performance Machining

Sep 3, 2024


The Miyano BNA-S2/DHY3 is a CNC lathe designed to excel in cutting bar stock. This machine combines space-saving design with sophisticated functions, making it ideal for machine shops that demand both efficiency and precision.

Features:

  • Space-saving design: The BNA series is known for its compact footprint, allowing you to maximize productivity in your workspace.
  • High performance: Despite its compact size, the BNA-S2/DHY3 delivers exceptional performance with round-the-clock stability and accuracy.
  • Easy to use: The BNA-S2/DHY3 is designed for fast setups and quick changeovers, minimizing downtime and maximizing production efficiency.

S2 Model:

  • Increased versatility: The S2 model features a sub-spindle for pick-off and back machining, allowing for more complex parts in a single setup.
  • Extensive tooling: An 8-station main turret with half-indexing capability, combined with multi-tool holders, provides exceptional tooling flexibility.
  • Advanced control technology: The S2 utilizes the latest control technology to reduce non-cutting time and improve overall productivity.

DHY3 Model:

  • Enhanced machining capabilities: The DHY3 takes the S2 model a step further with the inclusion of a powerful Fanuc 0i-TF control. This advanced control offers a wider range of CNC features for even greater machining possibilities.
  • Reduced machining times: The DHY3's combination of a Y-axis function in the main turret and a compact 6-station sub-turret allows for overlap processing and simultaneous machining on the main and sub spindles, significantly reducing machining times.

Overall, the Miyano BNA-S2/DHY3 is a versatile and high-performance CNC lathe suitable for a wide range of machining applications. Its compact design, ease of use, and advanced features make it a valuable asset for any machine shop.
