With the rapid development of China's shipbuilding, automobile, aerospace, steel, power generation equipment, and other industries, the center of the global manufacturing industry has been transferred to China. The market demand for complete sets of CNC laser cutting equipment in China has increased year by year. CNC laser cutting technology has gradually replaced the traditional processing means in the field of sheet metal processing with its flexibility and flexibility.
Nowadays, laser cutting equipment is more and more popular, but many users are not very proficient in the process of using CNC laser cutting machines. The following is an excerpt of the operating procedures of CNC laser cutting machines to share with you, hoping to be of great help to the majority of users when using CNC laser cutting machines.
Here is the content list:
Requirements for operators
Requirements for the operating environment
Precautions during operation
The operator of a CNC laser cutting machine must undergo professional technical training, be familiar with the structure and performance of the equipment, master the knowledge about the operating system, and be qualified before operation. Irrelevant personnel is forbidden to move in the work area to avoid accidents. The danger level of laser used in CNC cutting machine is 4. Its direct radiation and diffuse reflection can cause damage to the skin, especially the eyes. In addition, there is a high voltage of up to 30KV required for the operation of the laser, so it is not allowed to touch any components in the high voltage power supply before cutting off the power supply. When maintaining the laser, turn off the high voltage key switch and pull it out to lock the high voltage. In addition, be careful not to repair the laser alone.
The laser cutting machine is required to work in a cleanroom to avoid dust entering. The working environment of the machine must be kept clean. The ambient temperature should be kept at 15-25 ℃, not more than 5 ℃ higher than the cooling water temperature of the machine. When the cooling water temperature of the machine alarms, the machine should be shut down for some time, and the machine can only be started up after the temperature returns to normal. The fluctuation of the power supply network should be less than 10%. The equipment should be well-grounded. In addition, do not switch on and off frequently. Do not turn on the machine until at least 3 minutes after it is turned off.
The laser cutting machine needs high purity nitrogen, helium, and carbon dioxide. The purity of the gas must reach 99.999%. Failure to meet the requirements will reduce the life of the laser cutting machine and damage the lens easily. The purity of the gas can be verified by trial. If serious wire drawing condition is found in the smooth tube, the purity of the gas does not meet the requirements.
Do not use or store inflammable and explosive dangerous goods around the machine, including utensils and pipelines produced by inflammable and explosive gases. The fire extinguisher is required to be placed on the processing site. The laser cutting machine or shutter should be turned off when not processing. Do not place paper, cloth, or other flammable materials near the unprotected laser beam. The workpieces, plates, and wastes are stacked in order. Requirements before operation
The pressure of the water cooler should be adjusted to 3.5-4.0kg. If the pressure is too low, the laser cutting machine will give an alarm. If the pressure is too high, the water pipe will burst. Krypton lamp and xenon lamp used in the machine has a certain service life. In the case of weak light and dark light, it should be replaced in time to avoid light explosion. Before the CNC laser cutting machine is powered on, check whether there are obstacles around the machine and the working area of the workbench and whether all the air sources, water sources, and power supplies are in normal working condition. Then start the machine according to the order required by the regulations.
When using gas cylinders, avoid crushing wires and pipelines. The use and transportation of gas cylinders shall comply with the supervision regulations of gas cylinders and the use specifications of gas cylinders in the plant. Do not expose the cylinder to the sun or close to the heat source. When opening the bottle valve, the operator must stand on the side of the bottle mouth. Do not use corrosive reagents to clean the parts of the machine. Clean the optical parts regularly according to the operating procedures. When an alarm occurs during the operation of the program, the pause button should be used as far as possible to stop the operation, and then the corresponding operation processing should be carried out. The emergency stop button should be avoided as far as possible. After inputting the new workpiece program, it is necessary to test run and check its operation. When the machine is running, the operator shall not leave the post or do anything irrelevant to the processing. If any abnormality is found in the process of processing, stop the machine immediately, remove the fault in time or inform the production department. It is forbidden to process beyond the range. See the attached table for the processing range of the CNC laser cutting machine. The operation and regular maintenance of the laser should be carried out in strict accordance with the "laser operation guide" and "laser maintenance manual" provided by the machine tool manufacturer.
The above is how to operate the CNC laser cutting machine. Although these operations are very basic, the more trivial the details, the more related to the safety of the participants. Therefore, we must be cautious about these operation problems and operate in strict accordance with the operation process to ensure the safety of people and property.
