Product description
Haas ST-25Y Lathe
The Haas ST-25Y is an advanced CNC lathe that combines a compact footprint with the capabilities of large machining centers. It features the ST-30 series spindle, which improves the ST-20's spindle capacity, provides increased throughput, stronger chucking, and improved productivity. The addition of a Y-axis and live tooling transforms the ST-25Y into a mill-turn center capable of machining even the most complex parts in a single pass.
The new generation ST-25Y has been redesigned from the ground up, with a stiffer structure, improved ergonomics, and a greater range of Z-axis travel. Thanks to its more compact design, the machine now takes up 11% less space than the previous version, while offering higher productivity and new features.
Key features:
- New casting design – greater stiffness with smaller installation space,
- ST-30 spindle – larger throughput, stronger grip and higher cutting efficiency,
- Y axis and driven tools – milling, drilling and threading in one setup,
- Greater Z axis range – flexibility in processing longer workpieces,
- Integrated WiFi as standard – easy communication and program operation,
- Automatic door (optional) – improved ergonomics and cycle automation,
- Adapted to large production environments – reliable in continuous operation.
Application:
The ST-25Y is the ideal solution for shops requiring a mid-sized lathe with milling capability, capable of handling larger and more complex workpieces. It excels in both batch and piece production, guaranteeing precision, speed, and flexibility.
