Product description
Haas ST-20Y Lathe
The Haas ST-20Y, one of the most popular ST lathes, now features a Y-axis, live tooling, and a modern BMT turret. This allows the machine to offer full multi-tasking machining in a single setup—combining turning with milling, drilling, and tapping.
The new generation ST-20 has been completely redesigned. The machine is now more rigid, has a larger spindle bore (greater bar capacity), and has a wider Z-axis travel range, significantly expanding machining capabilities. Additionally, it offers Wi-Fi as standard and an optional automatic door, which improves ergonomics and enables easy integration with automation systems.
Key features:
- Y axis, BMT head and driven tools – milling, drilling and threading in one cycle,
- Larger spindle passage – processing of larger diameter bars,
- Increased Z-axis movement range – greater flexibility when working with longer details,
- Optional automatic doors – convenience and easier process automation,
- WiFi as standard – fast communication and easy program transfer,
- High stiffness and stability – precision and reliability even in large production series.
Application:
The ST-20Y is an excellent choice for companies seeking a versatile, mid-sized lathe with multi-axis machining capabilities. It excels in both batch and piece production, particularly in the automotive, machine tool, and aerospace industries where versatility, speed, and accuracy are key.
