Product description
Haas ST-55 Lathe
The Haas ST-55 is the largest model in the Haas lathe family, designed for heavy-duty machining of large-diameter components. It offers high cutting performance, exceptional structural rigidity, and excellent thermal stability, ensuring repeatable precision even under intense operation.
Equipped with two chucks, a high-torque spindle and large through-holes, the ST-55 lathe is ideal for machining heavy pipes, fittings, large couplings and long shafts.
Key features:
- The largest model of the Haas lathe – designed for machining large-sized parts,
- Very high stiffness and thermal stability – ensures accuracy and reliability in demanding processes,
- High torque spindle – ideal for working with massive and resistant materials,
- Possibility of working with two holders – greater flexibility and safety of mounting large components,
- Large through holes – enable the processing of pipes and long elements with large diameters.
Application:
The ST-55 is a solution for industrial plants processing heavy, long, and robust workpieces such as pipes, couplings, bushings, and drive shafts. The machine is ideal for applications requiring durability, power, and reliability in continuous operation.
