Double moving column CNC vertical lathe is a CNC vertical lathe with double column structure. It is usually used to process large and heavy workpieces, such as wheel hubs, gears, wind power towers, etc. Compared with the traditional single-column CNC vertical lathe, the double-moving-column CNC vertical lathe has higher stability, rigidity and processing capacity.
The following are some features and characteristics of double moving column CNC vertical lathe:

1. Double-column structure: The double-moving column CNC vertical lathe adopts a double-column structure, in which two columns support the headstock and beam. This structure can provide higher rigidity and stability, reduce vibration and deformation, and thus enable more precise machining.
2. Large workpiece processing capacity: Due to the large working range and carrying capacity of the double-moving column CNC vertical lathe, it can accommodate larger workpieces. This makes it ideal for machining large workpieces such as hubs with large diameters or high heights, gears and long shafts.
3. High rigidity: The double-moving column structure provides higher rigidity, which can resist cutting force and vibration. This is very important for processing workpieces with large cutting force and large processing depth, and can maintain good processing stability and processing quality.
4. Multifunctional processing: The double-moving column CNC vertical lathe is equipped with multiple tool holders and tool positions, which can realize multi-process processing operations. It usually has the functions of turning, boring, milling, tapping, etc. Through tool switching and axial movement, complex shapes and multi-process processing requirements can be realized.
5. High-precision processing: The double-moving column CNC vertical lathe adopts advanced numerical control system and high-precision sensors to achieve precise position control and processing operations. This ensures machining accuracy and surface quality that meet the requirements of high-precision industrial applications.

All in all, the double-moving column CNC vertical lathe is a high-rigidity CNC vertical lathe with a double-column structure, which is used for processing large and heavy workpieces. It has large workpiece processing capacity, high precision and multi-functional processing capacity, and is suitable for the processing needs of automobiles, aerospace, engineering machinery and other fields.
