Laser engraving can improve the efficiency of carving, making the surface of the carved area smooth and round, quickly reducing the temperature of the non-metallic material being carved, reducing the deformation and internal stress of the carved object; According to the different laser sources, they can be divided into CO2 non-metallic laser engraving machines and fiber optic metal engraving machines. CO2 non-metallic laser engraving machines generally use glass laser tubes in China, and some high-end laser engraving machines also use CO2 metal RF tubes.

1、 Pay attention to ensuring good grounding

In order to ensure the safety issues during the use of CNC engraving machines, grounding measures must be taken at the beginning to better protect the equipment and the safety of users. Manufacturers of high-quality and cost-effective CNC engraving machines also remind them to use specialized specifications for grounding wires, and to ensure that the power supply can work normally after grounding to prevent external machines from causing machine tool jumping and other situations. This operation can effectively extend the service life of the equipment.

2、 Pay attention to cleanliness and maintain good exhaust

The machine tool is a very important part of the composition of CNC engraving machines, so it is necessary to do a good job in cleaning and maintenance of this part in order to ensure its normal operation. Moreover, as the CNC engraving machine tool is a high-precision core component, special care should be taken when using it. For example, after polishing, it is necessary to wipe it clean and keep the bearings clean and lubricated. At the same time, each bearing should be regularly oiled to make the driving device flexible and carry out relevant inspections at any time.

3、 Pay attention to the smoothness of the cooling water

Usually, CNC engraving machines require the use of cooling water. At this time, it is necessary to maintain the flow of water, as the cooling water can extract the heat generated by the laser tube. Continuous flow can lower its temperature to a safe range, otherwise it may cause excessive heat and damage the equipment. So it is necessary to check at any time whether the cooling water of the CNC engraving machine is smooth. If any problems are found, the equipment should be promptly turned off and repaired.

The above three points are the maintenance precautions for CNC engraving machines, which are organized by Ruike CNC. Additionally, it is important to use the laser high-pressure button correctly. The manufacturer of high-quality CNC engraving machines also recommends completing one task at a time. If there is no continuous processing, the "laser high-pressure" should be turned off at any time. Operators are prohibited from leaving while the machine is working to avoid accidents. It is recommended to work continuously for no more than 5 hours and rest for 30 minutes in the middle.
