The steps for CNC vertical lathe to enter the power-on state are as follows:

1. Start-up preparation: First, check whether the CNC vertical lathe is clean and confirm whether all accessories and safety protection measures of the CNC vertical lathe are intact. Make sure the power cord and electrical system are well connected and free of faults.

2. Turn on the power: Insert the power plug of the CNC vertical lathe into the power socket and turn on the main power switch. Make sure the machine tool's power cord is well connected.

3. Turn on the CNC: Turn on the power switch of the CNC vertical lathe and wait for the control system self-test to be completed.

4. Start the spindle motor: Press the "Switch to Automatic" button on the CNC vertical lathe to start the spindle motor.

During the startup process of the CNC vertical lathe, you need to pay attention to whether the system is working normally, such as whether the hydraulic system and cooling system are running normally, whether the fan of the control cabinet is working normally, etc. If everything is normal, the CNC vertical lathe has successfully entered the power-on state and can proceed with subsequent processing operations.

Please note that the startup operation of the CNC vertical lathe needs to be carried out by professionally trained operators to ensure the safety and correctness of the CNC vertical lathe operation process. At the same time, follow the machine tool's instruction manual and operating procedures to ensure stable operation of the equipment and processing quality.
