Before working with a CNC vertical lathe, it is very important to conduct appropriate inspections to ensure the normal operation of the equipment and work safety. Here are some common inspection items:

1. Equipment appearance inspection: Check the appearance of the CNC vertical lathe to ensure that there is no obvious damage or abnormality to the machine tool itself.

2. Coolant check: Check the level and quality of the coolant. Make sure the cooling system is functioning properly to prevent overheating.

3. Lubrication system inspection: Check the lubrication system to ensure that all lubrication points are properly lubricated. Lack of lubrication can cause equipment failure.

4. Tool inspection: Check the status of the tool, including the wear of the tool and whether the clamping is firm. Replace or re-clamp the tool if necessary.

5. Workpiece clamping inspection: Check the workpiece clamping device to ensure that the clamping is firm and meets safety standards.

6. CNC system inspection: Start the CNC system and check whether the CNC system is running normally. Check whether the CNC program is loaded correctly.

7. Axis movement inspection: Check the movement of each axis to ensure that the axis moves freely and is not stuck. Calibrate each axis to ensure precise positioning.

8. Machine tool rigidity inspection: Check the rigidity and stability of the machine tool. Unstable machine tools can lead to vibration and inaccurate machining.

9. Safety system inspection: Check the safety system of the CNC vertical lathe, including emergency stop buttons, protective devices, etc., to ensure that the machine can be shut down quickly when needed.

10. Electrical system inspection: Check the electrical system to ensure that the cable connections are firm and the switches and buttons are normal.

11. Vacuum system inspection (if applicable): If the CNC vertical lathe uses a vacuum clamping system, check the vacuum pump and clamping device to ensure that they are working properly.

12. Pneumatic system inspection (if applicable): Check the pressure and pipeline of the pneumatic system to ensure that the pneumatic device is working properly.

When conducting the above inspections, operators should follow corresponding operating procedures and safe operating regulations. After ensuring that all inspections have satisfactory results, the CNC vertical lathe can be started for formal work.
