WY-250L
Nakamura-Tome’s WY-250L multitasking machines are twin spindle machines with two turrets, upper and lower, both with Y-axis.
With this configuration, manufacturing shops can drastically reduce cycle times by leveraging the WY-250L’s highly capable features such as pinch milling, drilling, and turning, as well as unique “off center” interpolative functions that can be performed on both spindles.
