HAAS AUTOMATION, INC. ST-30Y HORIZONTAL MACHINING CENTER

Technical Description

The HAAS ST-30Y is a precision CNC turning center engineered for advanced multi-axis machining operations. Featuring a robust 30 HP main spindle capable of 3,400 RPM, this machine accommodates workpieces up to 18 inches in turning diameter and 23 inches in length, with a maximum bar capacity of 3 inches and a 10-inch chuck. The machine's 31.75-inch swing over bed provides substantial clearance for complex component geometries. Equipped with a hybrid turret configuration, the ST-30Y manages up to 12 turning tools and 6 rotary tools with a 6,000 RPM auxiliary spindle for simultaneous milling, drilling, and tapping operations. The four-axis architecture includes 12.5 inches of X-axis travel, 4 inches of Y-axis travel for off-center operations, and 26 inches of Z-axis travel, all featuring rapid traverse rates of 472 IPM. This configuration enables efficient single-setup machining, reducing handling time and improving dimensional accuracy. The machine's heavy-duty sheet metal enclosure protects the operator while maintaining thermal stability critical for precision work. With consistent feed rates across all axes at 472 IPM and integrated HAAS CNC control technology, the ST-30Y delivers reliable performance across diverse applications including automotive, aerospace, and medical device manufacturing, combining versatility with repeatable accuracy for high-volume production environments.
