Specifications & Market Value

Technical Description
The Haas ST-20 Series is a compact yet powerful 2-axis CNC lathe designed for precision turning operations in small to medium-sized manufacturing environments. Featuring an 8.3-inch chuck and 2-inch bar capacity, this machine accommodates a variety of workpiece sizes while maintaining excellent rigidity and accuracy. With a maximum swing of 31.75 inches and a 10-inch turning diameter, the lathe provides adequate workspace for diverse applications. The machine delivers up to 21 inches of machining length, enabling efficient production of longer components in a single setup. Powered by a robust 30 HP vector drive with a maximum spindle speed of 5,000 RPM, the ST-20 generates substantial cutting torque while maintaining precision at high speeds. The intuitive Haas CNC control system offers user-friendly programming and operation, making it suitable for both experienced machinists and those new to CNC machining. The 2-axis configuration eliminates the need for a tailstock, simplifying setup and reducing footprint while still delivering consistent results for standard turning operations. Built with Haas's reputation for reliability and American manufacturing quality, the ST-20 Series combines productivity, precision, and ease of use, making it an ideal choice for job shops, tool rooms, and production facilities requiring versatile turning capabilities without unnecessary complexity.
