The Miyano BNA-42GTY is a top-of-the-line CNC lathe designed for high-productivity machining of complex parts. Manufactured by Citizen Machinery, this machine boasts a unique combination of features that make it ideal for a variety of industries.
Key Features:
- Dual Spindles and Turret/Gang Tool Combination: The BNA-42GTY features two spindles, a main spindle (SP1) and a sub spindle (SP2), along with a single turret and a gang tool slide. This configuration allows for simultaneous machining on both the front and back of a workpiece, significantly reducing cycle times.
- High Tool Capacity: The turret itself offers 8 stations, but with a half-indexing mechanism, it can effectively hold tools at up to 16 positions. Additionally, the gang tool slide and the option for multiple tool holders can further increase the total number of available tools to a maximum of 45. This versatility allows for complex machining operations to be completed on a single machine.
- Three-Axis Overlapping Machining: The BNA-42GTY's "Tooling Area Superimposition Control" enables simultaneous cutting with two tools on the main spindle and even three tools when utilizing both spindles. This overlapping functionality significantly improves machining efficiency.
- 42mm Bar Capacity: The machine can handle bar stock up to 42mm (1-5/8") in diameter, making it suitable for a wide range of parts.
- Sliding Headstock: Similar to a Swiss-style lathe, the BNA-42GTY incorporates a sliding headstock. This design allows for efficient machining of longer workpieces that wouldn't typically fit within the machine's overall footprint.
Specifications:
- Bar capacity: 42mm (1-5/8")
- Maximum number of tools: 45
- Spindle configuration: Dual spindles (main and sub)
- Tooling: Turret with half-indexing and gang tool slide
- Axis control: X, Y (2 axes), Z
- Additional features: Three-axis overlapping machining, sliding headstock
