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 various industries, including automotive, aerospace, and medical device manufacturing.
Key Features:
- Dual Spindles and Turret/Gang Tool Configuration: The BNA-42GTY features two spindles (main and sub) along with a turret and a gang tool slide. This allows for simultaneous machining on both the front and back of a workpiece, significantly reducing cycle times.
- High Tool Capacity: With its 8-station turret with half-indexing and optional multiple tool holders, the BNA-42GTY can accommodate up to 45 tools. This versatility enables complex parts to be machined in a single setup.
- 3-Axis Overlapping Machining: The BNA-42GTY's control system allows for three-axis overlapping machining on three separate systems (main spindle, sub spindle, and gang tools). This feature further optimizes machining efficiency.
- Y-Axis Equipped Turret: The Y-axis on the turret provides additional machining flexibility, particularly for off-center features and complex contours.
- Large Bar Capacity: The BNA-42GTY 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's sliding headstock allows for efficient machining of longer workpieces.
Specifications:
- Bar capacity: 42mm (1-5/8")
- Spindle speeds: Main spindle - 4,000 rpm, Sub spindle - 3,500 rpm
- Rapid traverse rate: 50 m/min (196 IPM)
- X-axis travel: 80 mm (3.15")
- Y1-axis travel: 60 mm (2.36")
- Y2-axis travel: 60 mm (2.36")
- Tool positions: Up to 45 (with optional multiple tool holders)
The Miyano BNA-42GTY is a powerful and versatile CNC lathe that offers significant advantages for manufacturers looking to improve productivity and efficiency in machining complex parts. Its combination of dual spindles, high tool capacity, and advanced machining capabilities make it a valuable asset for any machine shop.
