Double-column CNC vertical lathe is a kind of CNC vertical lathe, which adopts a double-column structure design. Compared with the traditional single-column vertical lathe, the double-column CNC vertical lathe has more advantages in terms of rigidity and stability, and is suitable for the processing of large and heavy workpieces.
The main features of the double-column CNC vertical lathe include:

1. High rigidity: The double-column CNC vertical lathe adopts two vertically arranged columns to support the worktable and the tool holder, which has stronger rigidity, can handle greater workpiece weight and cutting force, and ensures the stability and precision of processing.
2. High precision: The CNC system controls the movement of the tool holder and the worktable, which can realize high-precision processing and ensure the accuracy requirements of the geometric shape and size of the workpiece.
3. Large workbench area: Double-column CNC vertical lathe usually has a spacious workbench, which can accommodate large workpieces, and is especially suitable for processing workpieces such as large-diameter automobile wheels.
4. Versatility: This type of CNC vertical lathe can perform a variety of processing operations, such as turning, milling, drilling, boring, tapping, etc., and is suitable for processing workpieces with complex shapes.
5. High stability: The double-column structure provides better support and stability, reduces vibration and deformation, and improves processing quality and efficiency.

It should be noted that the double-column CNC vertical lathe is larger and takes up more space than the single-column vertical lathe. In addition, the design and configuration of the double-column CNC vertical lathe may vary depending on the manufacturer and model. When choosing a specific model that suits you, you must consider factors such as workpiece size, processing requirements, and production capacity.
To sum up, the double-column CNC vertical lathe has high rigidity, stability and precision, and is suitable for processing large and heavy workpieces, such as large-diameter automobile wheels. It is one of the processing equipment commonly used in fields such as the automobile industry.
