ST-25LY

The ST-25LY is a long-bed, big-bore turning center with Y-axis and C-axis
capabilities, allowing high-productivity, done-in-one machining operations.
The ST-25LY provides roughly double the Z-axis travel and turning length of
the standard ST-25Y for machining longer parts, while maintaining superior
cutting performance, and a compact footprint. The ST-25LY is engineered
from the ground up to create a rigid and high-performance machine. A wide
selection of productivity-enhancing options and powerful standard features
provides more value than ever before.
