When performing CNC vertical lathe processing, the following requirements need to be met:

1. Processing accuracy and surface roughness: CNC vertical lathe processing should ensure that the predetermined processing accuracy and surface roughness requirements are met. This requires precise adjustment of the CNC vertical lathe and the selection of appropriate tools and cutting parameters to ensure processing quality.

2. Reasonable selection of tools: The selection of CNC vertical turning tools has an important impact on the processing quality. When rough turning, tools with high strength and good durability should be selected to meet the needs of large back cutting and large feed rates; when CNC vertical turning and fine turning, tools with high precision and good durability should be selected to meet the needs of large back cutting and feed rates. Ensure the requirements of machining accuracy. At the same time, in order to reduce tool changing time and facilitate tool setting, machine-clamped knives and machine-clamped blades should be used as much as possible.

3. Selection of fixtures: The selection of CNC vertical lathe fixtures is also crucial. Universal fixtures should be used as much as possible to clamp the workpiece and special fixtures should be avoided to reduce positioning errors. In addition, the coincidence of part positioning datums also helps reduce positioning errors.

4. Selection of processing path: The processing path refers to the movement trajectory and direction of the tool relative to the part during the processing of the index-controlled machine tool. It should be ensured that the processing path can ensure the processing accuracy and surface roughness requirements, and the processing path should be shortened as much as possible to reduce the tool idle time to improve processing efficiency.

5. Safe operation: During the processing of CNC vertical lathes, safe operating procedures must be strictly followed. It is forbidden for irrelevant personnel to enter the machine tool working area to prevent abnormal situations from occurring. CNC vertical lathe operators should receive professional training to understand the performance structure and transmission system of the machine tool to avoid overload use. At the same time, ensure that the machine tool is clean and maintained, and promptly check whether the safety device and protective device are flexible and reliable.

In summary, when performing CNC vertical lathe processing, it is necessary to strictly abide by safety operating procedures while ensuring processing quality and efficiency to ensure the safety of equipment and personnel.
