In order to ensure the safety of laser operators and equipment, our department formulates the following safety operation procedures, and expects the operators to carefully read and strictly follow the following requirements:

1、 Before daily work

1. Check whether the water temperature of laser and chiller is normal. 2. Check whether the gas pressure meets the requirements.

3. Check whether the exhaust fan, cold dryer and industrial circulating water chiller work normally.

4. Check whether the focusing lens is polluted (the carbon dioxide laser directly pulls out the lens for observation, the fiber laser feels whether the temperature at the focusing lens housing is abnormal after half an hour of operation, and the equipment can be started only after no abnormality is found).

2、 Daily work

1. Start the machine in strict accordance with the order of opening and closing the machine to prevent burning out the electrical components of the machine, and bear the responsibility for equipment damage caused by illegal operation.

2. It is forbidden to turn on the power supply air switch with wet hands to prevent electric shock.

3. When opening the liquid gas, the face shall not face the gas exhaust port to prevent freezing injury. During operation, anti freezing gloves shall be worn. Smoking is prohibited beside the gas and in the workshop to prevent fire.

4. Confirm material type, material thickness and material size during cutting.

5. After calling in the program and adjusting the cutting parameters, simulate the cutting program, and execute the cutting program after ensuring that there is no error.

6. When operating the machine, the radiation protection door of the machine tool must be closed.

7. Anti radiation glasses must be worn when operating IPG laser, otherwise it is prohibited to operate the machine.

8. It is forbidden to directly look at the cutting sparks with naked eyes during the cutting process, otherwise, it will hurt the eyes.

9. Non professionals are not allowed to open the laser shell to prevent electric shock.

10. It is strictly forbidden for the operator to leave the console while the machine is running.

11. In the process of operation, if the parts need to be handled in case of rotation, it is necessary to suspend the program and turn the magnification to "O", and turn off the light before entering the working area of the machine tool to handle the fault. During the process of handling the fault, the operator is not allowed to enter the operating area to operate the machine.
