In the metal processing and manufacturing industry, many companies will use fiber laser cutting machines to help companies increase productivity and efficiency. Regarding the usual habits of laser cutting machines, we must maintain good switch machine habits. This can prevent errors and prolong the service life and stability of the machine. The fiber laser cutting machine should be operated by a dedicated person. In the case of multiple operations, a main operator must be appointed and the startup and shutdown operations must be strictly performed. Next, the editor of Wuhan Hongte Laser will introduce you the correct operation of turning on and off the machine. Come and learn.

Turn on the main power switch of the fiber laser cutting machine and the control power switch of each branch; 3 1. Turn on the voltage stabilizer and check whether the operating status of the voltage stabilizer is normal; 4. Turn on the power switch of the fiber laser and let the fiber laser with its own air conditioner or internal desuperheater run for more than 30 minutes; 5. When the fiber laser is turned on and run for 20 minutes Turn on the air compressor and check whether the air compressor is operating normally; 6. Open the air circuit control valve, turn on the refrigeration dryer, check whether the refrigeration dryer is operating normally, and check whether the air pressure is normal; 7. Open according to the cutting needs Cutting auxiliary gas control gas valve, check whether the cutting auxiliary gas pressure is normal; 8. Turn on the power switch of the machine tool, and press the power button to start the machine tool control system. After the control system starts normally, the machine tool returns to the origin; 9. The fiber laser turns on the power switch to run 30 Turn on the chiller to run after more than minutes, and check whether the chiller is operating 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 applied with high pressure, and check whether the fiber laser is operating normally; 11. Turn on the exhaust fan Or dust collector, check whether the operation status of the exhaust fan or dust collector is normal, and the fiber laser cutting machine enters the state to be cut.

Correct shutdown sequence:

1. Preparations before shutdown a. First move the cutting head to a high point, and stop the X and Y axes at a safe position. b. Exchange the workbench or stop the workbench in a safe position. 2. Turn off the high voltage of the laser, turn off the low voltage of the laser, wait about 3 minutes and then turn off the main power of the laser (the laser can be turned off immediately). Turn off all the key switches on the laser electric cabinet and remove them for safekeeping. 3. Press the emergency stop button on the side of the machine control panel and turn off the key switch, then remove the key for storage. Exit the operation page of the numerical control 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 of the chiller and dryer. 5. Turn off the stabilized power supply. 6. Turn off all cutting auxiliary gases before turning off the laser gas.

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