HAAS AUTOMATION, INC. ST-20SSY HORIZONTAL MACHINING CENTER

Technical Description

The HAAS AUTOMATION, INC. ST-20SSY is a high-performance horizontal machining center designed for precision turning and milling operations. It features a robust main spindle with a maximum turning diameter of 10.000", a maximum turning length of 21.000", and a chuck diameter of 8.300", supporting a maximum bar diameter of 2.000". The machine is equipped with a single main spindle capable of reaching 5,000 RPM and delivering 30 HP for demanding applications. The ST-20SSY utilizes a hybrid turret as its primary tool carrier, accommodating up to 12 turning tools and 12 rotary tools, with rotary tools capable of speeds up to 6,000 RPM. The system supports four axes of motion, including X, Y, Z, and C-axis, enabling complex multi-tasking operations. The X-axis offers 9.300" of travel with a rapid traverse rate of 472 ipm, the Y-axis provides 4.000" of travel at the same rapid traverse rate, and the Z-axis delivers 21.000" of travel with a rapid traverse rate of 472 ipm. All axes feature a maximum feed rate of 472 ipm, ensuring efficient material removal and high productivity. The machine is engineered for simultaneous cutting with one tool at a time, optimizing accuracy and surface finish. With its advanced control system, versatile tooling options, and robust construction, the HAAS ST-20SSY is ideal for a wide range of precision machining tasks in modern manufacturing environments.
