Product Description
Summary
The Miyano BNJ-51SY6 is a CNC turning center designed for simultaneous front and back machining with two spindles and Y-axis functionality. Its overlapping processing control, main and sub-spindle integration, and eccentric collet enable efficient complex part production including cranks, eccentric features, and large-diameter screws. The machine supports advanced milling and turning on a single platform, facilitating the manufacture of uneven and multi-process parts.
Key Capabilities
- Overlapping main spindle and sub-spindle control for reduced cycle times
- Y-axis on main turret for easy side milling of large-diameter or uneven parts
- Eccentric collet option supports complex eccentric machining such as crankshafts
- Simultaneous multi-tool machining with 12-station and 8-station turrets
- Live tooling with high spindle speeds for combined turning and milling operations
