ST-15LY

The ST-15LY is a long-bed, big-bore turning center that provides double the
Z-axis travel and turning length of the standard ST-15Y for machining
longer parts, while maintaining superior cutting performance, and a compact
footprint. The addition of Y-axis and live tooling allows milling,
drilling, and tapping on the face of the part and around the circumference
for increased machine capabilities. It offers a wide selection of
productivity-enhancing options, and more features and value than ever
before.
