A double-column CNC vertical lathe is a CNC vertical lathe with two columns. Its columns are located on both sides of the machine tool, supporting the spindle and worktable to provide a stable processing platform. The following are some features and advantages of double-column CNC vertical lathes:

1. Rigidity and stability: The double column structure provides better rigidity and stability. By adding column supports on both sides, vibration and deformation can be reduced, and processing accuracy and surface quality can be improved. This is particularly important for machining tasks that require high precision.
2. Processing capacity: Double-column CNC vertical lathes usually have a larger processing size range. Due to the stability of the double column structure, it can carry larger and heavier workpieces and perform a wider range of cutting operations. This makes it suitable for processing large mechanical parts, molds and other workpieces.
3. High-rigidity spindle: Double-column CNC vertical lathes are usually equipped with high-rigidity spindles. The high-rigidity spindle has better cutting stability and rigidity, and can maintain precise processing under high load conditions.
4. High precision and repeatability: The double-column CNC vertical lathe adopts an advanced CNC system and precise transmission structure, which can achieve high precision and repeatability processing. Accurate position control and stable cutting process ensure machining accuracy and consistency.
5. Multi-function and flexibility: Double-column CNC vertical lathes usually have multiple processing functions, such as turning, milling, drilling, etc. It can adapt to different types and complex processing tasks and has high flexibility.

In general, double-column CNC vertical lathes are widely used in aerospace, automotive, mold manufacturing and other industries due to their structural rigidity and stability, as well as their ability to process large workpieces and high precision. It provides a stable, efficient and high-precision solution for the processing of complex mechanical parts.
