2021 Haas ST-20Y CNC Lathe w/ Live Tooling

The 2021 Haas ST-20Y is a compact, high-performance CNC turning center designed for advanced part features requiring off-center milling, drilling, and tapping. Featuring Y-axis travel of ±2.0", the machine supports 3+1 simultaneous motion, allowing users to reduce setups and increase part accuracy. The machine boasts a maximum turning diameter of 13.75", maximum cutting length of 22.5", and bar capacity of 2.5", serviced by a 10" hydraulic chuck and A2-6 spindle nose. Powered by a 20 HP vector spindle motor, the main spindle reaches up to 4,000 RPM, and is equipped for rigid tapping and C-axis contouring.

A 12-station BMT65 turret supports both static and live tools, with live tooling reaching up to 6,000 RPM via Haas-built servo-driven motors. The NextGen Haas Control enables easy programming via Visual Programming System (VPS), macro support, and full integration with WIPS probing and tool management. Ideal for small-to-mid batch production, the ST-20Y offers thermal stability, repeatable accuracy, and robust American construction, making it a powerful addition to any modern machine shop.
