The 2012 Haas ST-40 is a large-frame big-bore turning center built around an A2-11 spindle nose with a 7" through-bore and 6.5" bar capacity, powered by a 60 HP 2-speed gearbox spindle delivering 1,400 RPM. Pair that with 17" X-travel, 44" Z-travel, 34.5" max swing, and 25.5" max cutting diameter, and the ST-40 turns large shafts, flanges, and chuck work that smaller turning centers cannot. Compared to the earlier Haas SL-40 it replaced, the ST-40 introduced a redesigned thermally-stable cast-iron base, a more rigid 12-station bolt-on turret, and the modern Haas Next Generation Control with a larger display, faster processor, and updated programming features. The combination delivers stronger spindle output, better thermal stability, and a more capable control than the SL-40 generation it succeeded.
