There are obvious differences between CNC vertical lathes and vertical machine tools in many aspects.

First of all, from the perspective of the spindle position and working method, the spindle of a CNC vertical lathe is vertical and its worktable is in a horizontal position, which is especially suitable for processing heavy parts with large diameter and short length. Vertical machine tools also have the characteristics that the spindle is in a vertical position and the workbench is in a horizontal plane, which makes the transportation and adjustment of the workpiece more convenient, and the weight of the workpiece can be well distributed on the workbench and frame. The overall Relatively stable.

Secondly, CNC vertical lathes have higher technical characteristics. For example, it may adopt a large box layout and provide a Z-axis ram with a large cross-section size to support ultra-heavy cutting. In addition, the CNC vertical lathe may introduce finite element analysis method and be specially designed for high efficiency, high rigidity, heavy cutting and other working conditions. Its spindle radial bearings and axial bearings may use high-grade double-row roller bearings and large-size thrust bearings to ensure high rotation accuracy and load-bearing capacity. CNC systems usually use well-known brands such as SIEMENS or FANUC.

Finally, from the perspective of processing capabilities and application scope, CNC vertical lathes are mainly used for processing high-precision, large-volume and complex-shaped parts, with good processing quality and stable accuracy. Vertical machine tools are more suitable for processing small batches, low precision requirements, and odd-job parts.

To sum up, there are significant differences between CNC vertical lathes and vertical machine tools in terms of spindle position, technical characteristics and processing capabilities. Which machine tool to choose depends mainly on the specific processing needs and workpiece characteristics.
