[Technical Specifications]
Haas ST-20 Y-Axis Lathes
The High-Performance Turning Centers
The ability to turn and mill complex parts and perform multiple
operations on a single machine increases throughput, reduces
handling, and improves part accuracy.
[ Specifications ]
The Haas ST-20 Series Y-axis turning centers provide 4" of Y-axis
travel (±2" from the centerline) for off-center milling, drilling,
and tapping, and come standard with 6000-rpm live tooling and
a servo-driven C axis for versatile 4-axis capability. They are
available in standard and Super Speed configurations.
