Product description
Haas ST-20 Lathe
The Haas ST-20 is a mid-sized CNC lathe designed for high productivity and flexible production. Compared to the smaller ST series models, the ST-20 features a fully programmable tailstock, which significantly simplifies working with longer workpieces thanks to its stable support and automatic position control.
The machine features a larger spindle bore, allowing for larger diameter bars, and an increased Z-axis travel range, providing a larger workspace. Thanks to its rigid construction and thermal stability, the ST-20 guarantees precision and repeatability, even during intense cutting cycles.
Key features:
- Fully programmable tailstock – comfortable work with longer workpieces, greater safety and precision of machining,
- Larger spindle passage – allows for processing thicker bar stock,
- Increased Z-axis range – flexibility in working with longer components,
- Optional automatic doors – improved ergonomics and the ability to automate tasks more easily,
- Wi-Fi as standard – fast communication and easy program transfer,
- Rigid construction and high thermal stability – reliability in intensive production.
Application:
The ST-20 is the ideal solution for companies needing a versatile mid-size lathe for working with larger bar stock and longer workpieces. Ideal for high-intensity production environments such as automotive, machine tools, and tooling, it offers the best balance of power, precision, and compact size.
