  In the metal processing and manufacturing industry, many enterprises will use the optical fiber laser cutting machine to help enterprises increase the production capacity and efficiency. As for the usual use habits of the laser cutting machine, it is necessary to keep a good habit of switching on and off the machine. This can prevent the occurrence of errors and extend the service life and stability of the machine. The optical fiber laser cutting machine shall be operated by a special person. When multiple persons operate it, a main operator must be appointed, and the start-up and shutdown operations shall be strictly carried out.

  Power on sequence:

  1. Check whether there is any object in the operation range of the machine tool that affects the safe operation of the machine tool;

  2. Turn on the main power switch and each branch control power switch of the optical fiber laser cutting machine; 3. Turn on the voltage regulator and check whether the operation state of the voltage regulator is normal;

  4. Turn on the power switch of the fiber laser, and let the fiber laser run for more than 30 minutes with its own air conditioner or internal desuperheater;

  5. Turn on the air compressor when the power switch of the fiber laser operates for 20 minutes, and check whether the air compressor operates normally;

  6. Open the air control valve of the air circuit, open the cold dryer, check whether the operation status of the cold dryer is normal, and check whether the air pressure is normal;

  7. Open the cutting auxiliary gas control valve according to the cutting needs, and check whether the cutting auxiliary gas pressure is normal;

  8. Turn on the power switch of the machine tool, press the power on button to start the control system of the machine tool, and when the control system starts normally, the machine tool returns to the original point;

  9. Turn on the power switch of the fiber laser for more than 30 minutes, and then turn on the chiller to check whether the chiller operates normally

  10. After the actual temperature of the high and low temperature water of the chiller reaches the set temperature ± 1 ℃, the fiber laser will be pressurized, and check whether the operation status of the fiber laser is normal;

  11. Open the suction fan or dust remover, check whether the operation state of the suction fan or dust remover is normal, and the fiber laser cutting machine enters the state to be cut.

  Correct shutdown sequence:

  1. Preparation before shutdown A. first move the cutting head to the high point, and stop the X and Y axes at the safe position. b. The exchange table or table stops in a safe position.

  2. Turn off the high voltage of the laser, turn off the low voltage of the laser, wait for about 3 minutes, and then turn off the main power supply of the laser (the laser can turn off the power supply of the laser immediately). Turn off all key switches on the laser cabinet and remove them for safekeeping.

  3. Press the emergency stop button on the control panel side of the machine tool, turn off the key switch, and remove the key for safekeeping. Exit the operation page of the CNC system, and turn off the power of the main control cabinet of the machine tool when the page prompts that the power can be turned off.

  4. Turn off the power supply of chiller and dryer.

  5. Turn off the regulated power supply.

  6. Turn off all cutting auxiliary gas before turning off the laser gas.

  7. Turn off the power supply of the air compressor and open the air tank drain valve.
