The startup and shutdown of CNC vertical lathes are key steps in CNC machining operations, and the following aspects need to be noted:

Before startup:

1. Check environmental safety: Ensure that the environment around the CNC vertical lathe is safe, clear obstacles in the working area, and ensure that operators and other personnel are away from the machine tool.

2. Check the machine tool status: Check whether the various mechanical parts of the CNC vertical lathe are normal, including the clamping device, tool, tool magazine, lubrication system, etc., to ensure that there is no damage or abnormality.

3. Check the power supply system: Ensure that the power supply wiring of the CNC vertical lathe is correct, the power supply system is stable, and the power line and plug are intact.

4. Check the coolant and lubrication system: Ensure that the coolant and lubrication system of the CNC vertical lathe are working properly, sufficient and leak-free, to ensure the cooling and lubrication of the tool and workpiece during the machining process.

5. Check the CNC system: Ensure that the power supply of the CNC vertical lathe is normal, the screen display is normal, there is no fault alarm, the program is loaded correctly, and it can run normally.

When starting:

1. Follow the startup sequence: According to the CNC vertical lathe operation manual or operation process, start the various functions of the machine tool step by step in the correct order to ensure that each function starts normally.

2. Pay attention to warning signals: Pay attention to the warning signals and alarm information of the CNC system, deal with possible problems in time, and ensure that the machine tool runs stably.

3. Check movement in manual mode: When starting the CNC vertical lathe, you can select manual mode to gradually check whether the movement of each axis is normal to ensure that there is no abnormality in each part of the machine tool.

Before closing:

1. End the processing program: Before closing the CNC vertical lathe, the current processing program should be ended and the machine tool should be returned to a safe position.

2. Clean the work area: Clean the CNC vertical lathe worktable, cutting waste and processing fluid, etc. to ensure that the work area is clean.

3. Safe recovery of tools: Place the CNC vertical lathe tools in a safe place or tool magazine to avoid accidental injury or damage to the tools.

4. Shut down the system: According to the CNC vertical lathe operation manual or process, gradually shut down the CNC system and power supply to ensure the correct shutdown sequence.

5. Check the equipment status: After shutting down the CNC vertical lathe, check whether all parts are intact and confirm that the machine tool is in a safe state.

6. Record relevant information: If necessary, record the operation status, processing parameters, fault information, etc. of the machine tool for future reference.

In general, it is necessary to operate carefully when starting and shutting down the CNC vertical lathe, and proceed step by step according to the operation manual or operation process to ensure the safe and stable operation of the equipment and the safety of the operator.
