Product Description
Summary
The Haas ST-45SY Short-Bed Y-Axis Lathe is a CNC turn-mill machine configured for large-diameter part processing with full C-axis interpolation, live tooling, and Y-axis milling capabilities. It enables both turning and milling operations—including drilling and tapping—on a single setup, with a short bed to reduce floor space requirements. Key technical features include a 12-station BMT75 turret, a 7.0" spindle bore, and ±3.0" Y-axis travel for complex part geometries and secondary machining operations.
Key Capabilities
- Turning, milling, drilling, and tapping operations enabled in one setup
- Y-axis travel (±3.0") for off-centerline milling
- Fully interpolated C-axis for contouring and positioning
- 12-station BMT75 live tooling turret
- 7.0" bore A2-11 spindle for large-diameter parts
- Rapid traverse across X, Y, Z axes
- Haas CNC control system with remote monitoring, touchscreen, and advanced tool management
- Optional automation features including auto door and edge sensor
