CNC vertical lathe is a high-precision machine tool for turning shaft parts and the like. The following are some common processing requirements of CNC vertical lathe:

1. Dimensional accuracy: CNC vertical lathes are required to meet the dimensional accuracy requirements of the required parts. This includes precision control of diameter, length, axiality, roundness, etc.
2. Surface quality: CNC vertical lathe needs to be able to ensure that the processed parts have good surface quality, such as smoothness, flatness, roughness, etc. This usually requires selection of appropriate cutting process parameters and tools, and proper grinding and polishing.
3. Axial accuracy: CNC vertical lathe needs to control the axial straightness and roundness when processing shaft parts. This ensures that the axis of the part is as required for fit and function accuracy.
4. Angle accuracy: CNC vertical lathe also needs to control the angle accuracy of the processed parts, including the consistency of angle size and angle change. This is especially important when machining parts such as bevels, tapers or inclined holes.
5. Processing efficiency: CNC vertical lathes need to have high-efficiency processing capabilities and be able to complete parts processing in a short period of time. This is usually achieved by selecting the appropriate feed rate, rotational speed and cutting process parameters.
6. Automation and programming: CNC vertical lathe has automatic operation and programming capabilities, requiring operators to be familiar with CNC programming and operating skills, and be able to accurately set processing parameters and programs, and monitor and adjust them.

It is important to note that specific machining requirements may vary depending on part shape, material and application. In practical applications, according to the requirements of specific parts, precise processing parameter selection and processing technology optimization can be carried out to meet the requirements for precision, quality and efficiency.
