CNC Double Column Vertical Turning Lathe: Precision for Heavy-Duty Vertical Machining

In modern industries that demand high-precision machining of oversized components—such as aerospace, power generation, mining, and shipbuilding—the CNC Double Column Vertical Turning Lathe (VTL) stands as an indispensable solution. With its robust structure and twin-column support system, this machine ensures outstanding stability, cutting accuracy, and efficiency when handling large-diameter and heavy workpieces.

Superior Structural Design for Heavy Components

The double-column architecture provides enhanced rigidity and thermal stability, critical when processing components weighing several tons. The symmetrical design of the gantry minimizes deflection and vibration, ensuring superior surface finish and tight tolerances.

The vertical spindle orientation allows gravity to aid in the secure positioning of workpieces, improving machining precision for large-diameter components such as flanges, turbine casings, bearing housings, and gear blanks.

Key Features of CNC Double Column Vertical Turning Lathe

• High Rigidity Double-Column Frame: Reinforced with heavy-duty cast iron, the structure resists deformation under heavy load and high-speed cutting.

• Large Swing Diameter: Capable of handling workpieces up to 4000 mm or more, depending on the model.

• Servo Motor Driven CNC System: Incorporates advanced control systems like FANUC, Siemens, or GSK for high-speed and high-accuracy interpolation.

• Hydrostatic or Box Ways: Support smooth table movement, increasing wear resistance and damping for better surface finish.

• Automatic Tool Changer (ATC): Equipped with vertical turret or RAM-type ATC for multi-tool operations, reducing setup time.

• Live Spindle (Optional): Allows for milling, drilling, and tapping without additional setups.

• Integrated Chip Conveyor and Coolant System: Ensures smooth chip removal and optimal cutting temperature control.
