The basic performance of CNC vertical lathe is mainly reflected in the following aspects:

1. Processing range and accuracy: The processing objects of CNC vertical lathes are usually higher-precision parts, so the processing accuracy requirements are very strict. Common accuracy indicators include roundness error, straightness error, segment error and surface roughness, etc., which all need to meet specific numerical requirements. At the same time, CNC vertical lathes have large processing diameters and are mainly used to process large and heavy workpieces with large diameters and short lengths, as well as workpieces that are difficult to clamp on horizontal lathes.

2. Rigidity and stability: The castings of CNC vertical lathes are made of high-strength materials and are specially treated to eliminate internal stress, making them extremely rigid and stable. This design ensures that the machine tool can resist various cutting forces and maintain stable operation during the machining process.

3. Workbench and spindle performance: The workbench of the CNC vertical lathe uses dynamic pressure guide rails with large load-bearing capacity. The spindle diameter adopts a specific type of roller bearing to ensure the stability and rotation accuracy of the spindle. At the same time, the tool holder design also fully takes into account the processing needs, using hydraulic balancing and other methods to ensure the stability and accuracy of the tool.

4. Control system: The control system of the CNC vertical lathe is excellent and can achieve high-precision and high-efficiency processing. Through PLC control and digital display devices, the machine tool can accurately process according to the preset program, greatly improving processing efficiency and quality.

5. Key parameters: Some key parameters of CNC vertical lathe, such as maximum processing diameter, maximum processing length, spindle speed and feed speed, are all set according to processing requirements. The selection of these parameters directly affects the processing capability and efficiency of the machine tool.

In general, CNC vertical lathes play an important role in the field of hardware and metal processing due to their performance characteristics such as high precision, high rigidity, high stability and excellent control systems. At the same time, these performance characteristics also ensure that CNC vertical lathes can perform well in various complex and delicate processing tasks.
