The ST-40Y adds Y-axis motion to our shop-proven ST-40 to create a large-frame turning center with a generous work envelope and secondary milling capabilities. The addition of Y-axis motion, C-axis interpolation, and live tooling allows milling, drilling, and tapping for increased machine capabilities. This machine offers the best performance for the money – the best value – in its class.
- 12-station base mount turret (BMT75)
- A2-8 spindle nose with 4.0″ (102 mm) bar capacity
- Y-axis milling, drilling, and tapping
