Not your basic single turret, twin spindle machine
The Miyano BNA42SY is a high-performance fixed-head CNC lathe designed for precision machining of bar materials up to 42 mm. Built with a strong cast-iron base and hand-scraped slideways, it ensures long-term rigidity and stability—especially critical in Indian shop-floor conditions where machines must handle both light and heavy-duty applications reliably.
Equipped with a main spindle and sub spindle, along with a 12-station turret with Y-axis, this machine enables simultaneous machining on both ends of the component, reducing cycle times significantly. Whether you are machining hydraulic parts, precision automotive components, or medical devices, the BNA42SY offers superior dimensional accuracy and surface finish.
What sets it apart is LFV (Low-Frequency Vibration) chip-breaking technology—an ideal solution for Indian companies often machining stainless steel, alloy steels, or aluminum. This technology helps avoid tangled swarf and extends tool life, ensuring smoother operations with fewer interruptions.
With compact dimensions (just over 2.3 meters wide), low power consumption (~12 kVA), and compatibility with bar feeders and robots, it’s an ideal solution for SMEs and large-scale factories alike looking to upgrade their production without compromising on quality or floor space.
