When using a vertical CNC lathe, there are several important things to pay attention to:

1. Safe operation: Always follow the safe operating procedures and operating manual of the vertical CNC lathe. Ensure that operators are familiar with the machine tool's safety devices and the location of the emergency stop button, and strictly follow the operating procedures to avoid accidents.

2. Position the workpiece: When installing and clamping the workpiece on the vertical CNC lathe, ensure that the workpiece is firmly fixed on the workbench to prevent the workpiece from moving or falling off during processing, causing processing deviations or safety hazards.

3. Tool selection: Select the appropriate tool according to the vertical CNC lathe processing requirements, and ensure that the tool is installed correctly and firmly. Check whether the cutting edge of the tool is severely worn, and replace damaged tools in time to ensure processing quality and safety.

4. Processing parameter settings: According to the vertical CNC lathe processing material and process requirements, correctly set the processing parameters, including cutting speed, feed speed, cutting depth, etc., to ensure a stable processing process and good processing quality.

5. Monitor the processing process: During the processing of the vertical CNC lathe, the processing status and processing quality should be checked regularly. Especially for workpieces processed for a long time, the processing quality should be checked regularly to ensure processing accuracy and surface quality.

6. Regular maintenance: Regularly inspect and maintain the vertical CNC lathe, including the lubrication system, transmission system, CNC system, etc., to ensure smooth operation of the machine tool and extend the service life of the machine tool.

7. Training operators: Ensure that vertical CNC lathe operators have received professional training and have the necessary skills and knowledge to use vertical CNC lathes to ensure safe operation and processing quality.

By following the above operating precautions, the vertical CNC lathe can effectively ensure the safe operation and high-quality processing of the vertical CNC lathe.
