USED HAAS ST20Y

The Haas ST‑20Y is a compact yet powerful CNC turning center with integrated Y-axis, C-axis, and live tooling, enabling true mill-turn operations. Unlike traditional 2-axis lathes, the Y-axis functionality adds off-center milling, drilling, and tapping capabilities, making it highly versatile for complex parts — all within a single setup.

As part of the ST (Small Turning) series, the ST‑20Y balances power, speed, and precision with a small footprint. It features a 12-station hybrid turret, robust spindle construction, and Haas’ Next-Generation Control, all engineered for high-mix, high-accuracy production environments.

This machine is ideal for manufacturers seeking to eliminate secondary operations by combining turning and milling, resulting in faster cycle times, improved accuracy, and reduced handling. The ST‑20Y is popular in aerospace, medical, automotive, job shops, and toolroom applications where flexibility and productivity are key.
