The Miyano BNJ-51SY6 is a CNC sliding headstock lathe designed for high-production machining of complex parts up to 2 inches in diameter. This machine boasts a combination of features that make it a versatile and efficient option for manufacturers.
Key Features:
- Simultaneous Front and Back Machining: The BNJ-51SY6 features a unique design with a stationary main spindle headstock and a traversing main turret with X and Y-axis capability. This allows for simultaneous machining on the main spindle and sub-spindle, significantly improving cycle times.
- Enhanced Sub-spindle Functionality: The latest BNJ model introduces an 8-station sub-turret with the ability to mount up to four live tool spindles. This expands the machine's capabilities for complex machining on the sub-spindle.
- Powerful Main Turret: The 12-station main turret offers excellent flexibility and can now accommodate live tools with up to 25 Nm of torque, allowing for more demanding machining operations.
- Y-axis on Main Turret: The Y-axis capability on the main turret opens doors to a new level of machining possibilities. Complex tasks like plane milling, pocket milling, and large-diameter helical threading become achievable on the BNJ-51SY6.
- Fanuc 0i-TF Control: The machine comes equipped with the latest Fanuc 0i-TF control, offering a wide range of CNC functionalities that enhance programming ease and efficiency.
