Product Description
Summary
The Haas ST-45S Short-Bed Lathe is a CNC big-bore turning center engineered for large-diameter part turning, pipe threading, and end work on long shafts, especially when both ends must be supported. Its large through-bore spindle, 12-station bolt-on turret, and available rear spindle nose enable efficient machining of oversize and tubular components. The short-bed configuration minimizes floor space requirements while maintaining significant swing and cutting capacities.
Key Capabilities
- Supports turning of large-diameter components with a maximum part swing of 35.5 in (902 mm)
- 7.0 in (178 mm) large spindle bore accommodates significant bar stock and pipe threading operations
- 12-station bolt-on turret with hydraulic clamping for tooling flexibility
- Two-speed gearbox for high torque at low speeds (up to 1400 ft-lbf at 150 rpm, standard)
- Optional rear spindle nose for supporting long workpieces and pipe rethreading
- Tailstock with MT5 taper and 26.0 in travel for additional support during long-part machining
- Haas control features including touchscreen display, remote monitoring (HaasConnect), and advanced tool management
