HAAS ST-20T CNC LATHES
Specifications & Market Value

Technical Description
This CNC lathe features an 8-inch chuck and operates on 2 axes (X and Z), providing precise control for turning operations. Powered by a 20 HP motor, it achieves a maximum spindle speed of 4,000 RPM, enabling efficient machining of various materials. The machine supports a maximum turning diameter of 10.3 inches and a maximum swing of 23 inches, facilitating the handling of workpieces of considerable size. The machining length capability is 24 inches, allowing for the production of moderately long parts. The X-axis travel measures 8.45 inches, reflecting the cross-slide movement, while the Z-axis travel is 20 inches, indicating the carriage travel along the bed for longitudinal cuts. Rapid traverse rates reach up to 710 inches per minute, supporting fast positioning and reducing cycle times. A tailstock is included, which enhances support for long workpieces during turning or drilling operations. This combination of specifications makes the lathe suitable for precision turning tasks requiring moderate size and power, balancing robust performance and versatility in typical industrial or workshop settings.
