Double Column Vertical CNC Lathe

The Double Column Vertical CNC Lathe is engineered for turning large-diameter, high-tonnage components requiring maximum stability and heavy cutting torque.

Mounting workpieces vertically on the rotary table allows their weight to be supported directly by the machine base, eliminating the deflection and sagging common in horizontal lathes. The dual-column frame supports the cross rail from both sides, forming a rigid box structure that minimizes vibration during high-depth roughing and precision finishing.
