Product description
Haas ST-45SY – Compact Y-axis lathe with large through-bore
The Haas ST-45SY is a short-bed version of the ST-45Y lathe, designed for large-diameter turning in tight spaces. It retains all the power and reliability of the larger model, but with a shorter Z-axis travel, it takes up less shop floor space.
Equipped with a Y axis, an interpolated C axis, and driven tools, the machine can simultaneously perform turning, milling, drilling, and threading in a single setup. This significantly reduces machining time and increases production flexibility.
Key features:
- 12-station BMT75 tool head,
- A2-11 spindle nose with large through hole 178 mm (7.0"),
- Y-axis movement range ± 76 mm (± 3.0"),
- Fully interpolated C-axis for precise indexing and milling operations,
- Compact design with short bed – less space, same performance.
The ST-45SY is the ideal solution for shops that need the power of a large lathe, multi-operation capabilities and a compact size.
