2011 Haas ST-20 CNC Lathe

The 2011 Haas ST-20 is a precision two-axis CNC turning centre engineered for robust performance and versatility. It delivers a maximum swing over bed of 31.75?inch, a turning diameter of up to 15?inch with the BMT turret, and a machining length of 20.5?inch (21.0?inch between centers). The X-axis offers 9.3?inch travel and the Z-axis 21?inch travel, powered by a 20?HP spindle motor rotating at up to 4?000?RPM through an A2-6 spindle nose and 3.5?inch spindle bore, supporting bar stock up to 2?inch in diameter. A 12-station bolt-on-style turret, hydraulic tailstock, automatic tool presetter, and rigid tapping functionality are included, with optional upgrades such as Big-Bore 30?HP bar capacity and parts catcher with bar-feed compatibility for extended flexibility.

This lathe is equipped standard with Haas CNC control, a belt-drive system for thermal stability, rigid construction for high accuracy, and a 55-gallon coolant tank feeding an integrated chip conveyor. It is fold-down accessible, includes early power-failure detection, USB/Ethernet ports, memory lock keyswitch, and optional Wi-Fi and auto-door features—making it ideal for high-productivity environments ranging from aerospace to job-shop operations.
