HAAS AUTOMATION, INC. ST-45L HORIZONTAL MACHINING CENTER

Technical Description

The HAAS Automation Inc. ST-45L Horizontal Machining Center is a heavy-duty CNC lathe engineered for precision and large-scale turning tasks. It features a robust main spindle capable of handling a maximum turning diameter of 25.5 inches and a turning length up to 80 inches, supported by an 18-inch diameter chuck and a 34.5-inch maximum swing. The spindle accommodates bar stock diameters up to 6.5 inches and operates at speeds up to 1,400 RPM, powered by a 40 hp motor with an optional upgrade to 55 hp, ensuring optimal torque and cutting force. The machine is equipped with a 12-station turret allowing up to 12 tools for turning operations, with live rotary tooling up to 6,000 RPM, facilitating versatile machining capabilities. It operates on a 2-axis CNC system with X-axis travel of 17 inches and Z-axis travel of 80 inches, both axes capable of maximum feed rates and rapid traverses of 710 inches per minute, promoting fast and precise material removal. The turret’s hydraulic clamping improves rigidity and accuracy during heavy metal removal processes. Designed for high thermal stability and structural rigidity, the ST-45L excels in machining long shafts and tubing for sectors including aerospace, automotive, and heavy manufacturing. Its long-bed configuration extends workpiece capacity, making it suitable for large-scale production runs requiring consistent accuracy and heavy cutting capacity. Additional features often include hydraulic steady rest and tailstock support for enhanced workpiece stability during machining operations. This lathe balances performance and value as a high-capacity, versatile turning center ideal for demanding industrial applications.
