Summary

The Citizen Machinery Miyano BNA-42GTY is a CNC multi-spindle turn-mill center engineered for complex bar work. Its dual spindles, combination of turret and gang tool post, and capability for 3-axis overlapping machining enable simultaneous multi-system operations for high productivity workflows. The system is suitable for precision production involving short bar workpieces and multi-operation turning and milling tasks.

Key Capabilities

• Simultaneous machining with 2 spindles and 3-axis overlap across 3 systems
• Integrated turret (8-station, half-indexing mechanism) and gang tool post
• Supports both turning and milling operations on bar stock
• Accommodates rapid tool motion across multiple axes for efficient cycle times
