The processing scale of CNC vertical lathe can be determined according to the size of the machine tool, the power of the spindle and the characteristics of the processing operation. The following are some common process size ranges:

1. Workpiece size: CNC vertical lathe can be applied to the processing of workpieces in different size ranges, from small workpieces to large workpieces. The specific workpiece size limit depends on the table size and stroke of the machine tool, which can usually handle workpieces with diameters or side lengths ranging from tens of millimeters to several meters.
2. Material type: CNC vertical lathe is suitable for processing various metal and non-metal materials. Common metal materials include steel, iron, aluminum, copper, stainless steel, etc., and non-metallic materials such as plastics, wood, etc. can also be processed.
3. Accuracy requirements: CNC vertical lathe can realize high-precision processing, and the specific processing accuracy is affected by factors such as the accuracy of the machine tool itself, cutting tools, and workpiece fixation. Generally, CNC vertical lathes can achieve a processing accuracy of several microns.
4. Processing efficiency: CNC vertical lathe has high-efficiency processing capability, which can realize faster cutting speed and high feed speed, and improve production efficiency. The specific machining efficiency depends on factors such as cutting parameters, workpiece material and complexity of machining operations.

Generally speaking, the processing scale of CNC vertical lathe has certain flexibility in terms of size, material type and processing requirements. The specific processing scale can be determined according to the technical parameters of the machine tool, the design requirements of the workpiece and the production demand. Different types of CNC vertical lathes may have different processing scales, so when selecting and using CNC vertical lathes, it is necessary to make a reasonable choice according to specific processing requirements.
