STE46/52 Double-spindle double-tool-tower CNC lathe

STE46/52 Double-spindle double-tool-tower CNC lathe

The equipment features a 35° slant-bed design with a fixed main spindle, and a sub-spindle that moves along the Z-axis, ensuring high concentricity and alignment accuracy during part transfer. It is equipped with two Y-axis BMT45 power turrets, providing strong process compatibility for complex workpieces and enabling turning, milling, drilling, and tapping operations. Each spindle’s machining is performed independently by its respective turret, reducing machining time by more than 40%. The machine supports both long-bar and short-blank processing and offers high adaptability for automation, with optional configurations such as long bar feeders, gantry robots, or articulated robotic loading/unloading systems.

The equipment’s cast components are made of HT300 gray cast iron. C3-grade ball screws are from Taiwan HIWIN/PMI, and linear guides and roller sliders are also from Taiwan HIWIN/PMI. Bearings are supplied by Japan’s NACHI or NSK. The main spindle can be configured with a Taiwan Posa spindle or an equivalent domestic mechanical spindle, while the sub-spindle can be configured as a disk-type motor spindle or built-in electric spindle. Both the servo motors and the control system are from Taiwan SYNTEC, with the control system being the 22TB model.
