Working Principle

A CO2 laser machine uses a glass laser tube to produce light beam, and works with a numerical control system to irradiate the beam to the surface of the object, and at the same time release high energy to melt and evaporate the surface of the object, thereby realizing the plan of cutting and engraving. The beam is a column of very high intensity light, of a single wavelength, or color. In the case of a typical carbon dioxide laser, that wavelength is in the Infra-Red part of the light spectrum, so it is invisible to the human eye. The beam is only about 3/4 of an inch in diameter as it travels from the resonator, which creates the beam, through the machine's beam path. It may be bounced in different directions by a number of mirrors, or "beam benders", before it is finally focused onto the plate. The focused beam goes through the bore of a nozzle right before it hits the plate. Also flowing through that nozzle bore is a compressed gas, such as Oxygen or Nitrogen. Generally speaking, higher power is used for cutting, lower power is used for engraving. The power is adjustable during operation. Turn it down for engraving and turn it up for cutting. The level of power will also affect the depth of engraving and the thickness of cutting.

From the technical and economic point of view, carbon dioxide laser machine is not suitable to cut thicker sheet metals compared with fiber laser machine. The typical products that have been used are automatic elevator structural parts, elevator panel, machine tool and grain machinery enclosures, various electrical cabinets, switch cabinets, textile machinery parts, engineering machinery structural parts, large motor silicon steel sheets.

Patterns, signs, marks non-metallic materials (generally 20 mm thick) for decoration, advertising and service industries, such as the design of art photo albums, the marks of companies, units, hotels, shopping malls, Chinese and English fonts in stations, docks, and public places.

Special parts that require even slitting. The most widely used typical part is the die-cutting board used in the packaging and printing industry. It requires a slot with a width of 0.7 to 0.8 mm on a 20 mm thick wooden template, and then inserts a blade in the slot. Use fashion on the die-cutting machine to cut out various packaging boxes with printed graphics. A new field of application in recent years is the oil screen pipe. In order to block the sediment from entering the oil pump, a uniform slit with a width of 0.3 mm is cut on the alloy steel pipe with a wall thickness of 6 to 9 mm, and the diameter of the small hole at the starting and cutting hole cannot be greater than 0.3mm.

How To Use?

It is very dangerous for a CO2 laser cutter to break down during work. Novices must be trained by professionals before they can operate independently. SENYO experts have summarized 13 easy-to-follow steps for safe work based on experience as follows.

1. Prepare the materials to be cut and fix them on the workbench.

2. Call the corresponding parameters according to the material and thickness.

3. Select the corresponding lens and nozzle according to the cutting parameters, and check whether they are in good condition.

4. Adjust the cutting head to the appropriate focus.

5. Check and adjust the centering of the nozzle.

6. Calibration of cutting head sensor.

7. Check the cutting gas, enter the command to open the auxiliary gas, and observe whether it can be ejected from the nozzle well.

8. Trial cut the material, check the cross-section, and adjust the process parameters until the production requirements are met.

9. Prepare the cutting program according to the drawing required by the workpiece, and import it to the controller.

10. Move the cutting head to the starting point to be cut, and press "Start" to execute the cutting program.

11. The operator is not allowed to leave the machine tool during the cutting process. In case of emergency, quickly press the "Reset" or "Emergency Stop" button to terminate the operation.

12. When cutting the first workpiece, stop cutting to see if it meets the requirements.

13. Pay attention to check the auxiliary gas flow when cutting, and replace it in time when the gas is insufficient.

How To Maintain?

A CO2 laser cutter must be cared for and maintained regularly and regularly, so that it can engrave and cut more accurately and at a higher speed for you, which can also prolong the service life of the machine. We summarizes 13 maintenance tips for everyone as follows.

1. When using the machine, the device should be turned on or off in strict accordance with the correct boot sequence.

2. The machine shell, laser power supply, and computer power supply must be well grounded. Regularly check whether the grounding screw is rusted or loose, and clean and fasten it in time.

3. Before starting work every day, observe whether the focusing lens is polluted, and clean it in time if any. Please be careful not to use too much force when cleaning the reflector, otherwise it will cause the optical path to shift! The maintenance of reflective lenses and focusing lenses at all levels should follow the principle of "cleaning in time if there is pollution". Special lens cleaner must be used for cleaning.

4. Before each machine works, please check whether each limit switch is working normally, so as to ensure that the equipment will not have collisions that affect the accuracy of the equipment during the working process. In addition, please pay attention to adjust the focal length and lock it tightly to ensure that the processing effect will not be affected by the decrease of the focal length, or even mechanical collision will occur.

5. If the moving parts such as trolley pulleys, slideways and linear guide rails are polluted or corroded, it will directly affect the processing effect. They should be cleaned regularly and lubricated on the guide rails to prevent rust.

6. After a long time of use (especially cutting), the honeycomb platform will stick to processing waste and even block the honeycomb holes. It may smoke or even burn when exposed to beam. It should be removed regularly.

7. The cooling water should be kept clean and replaced regularly. During processing, check whether the water level is sufficient and whether the water temperature is too high. It is strictly forbidden to use inferior circulating water. Poor-quality water can seriously affect the laser power and greatly shorten the service life of the laser tube. The damage to the tube caused by the use of poor-quality water by the user is not covered by the warranty. It is recommended to use pure water. The amount of cooling water should not be less than 30 liters, and the submersible pump must be submerged. During the working process of the machine, the water temperature must be checked at any time (the best working water temperature is 25~30°C, the maximum water temperature cannot exceed 35°C, and the minimum water temperature cannot be lower than 5°C). Once the water feels warm, it should be changed immediately. The water change method that does not affect the work is to discharge part of the hot water and then flush with cold water. Every three days, the water tank, water pump (especially the filter sponge of the water pump) and the water inlet and outlet hoses must be cleaned.

8. The laser tube is cooled by circulating water, so some white scale will appear in the tube after long-term use. We can add a small amount of vinegar to the circulating water, then take out the groove and rinse its interior with clean water to keep it in the best working condition and prolong its service life.

9. Pay attention that the smoke exhaust port and the exhaust duct cannot be blocked, and check and remove the obstruction at any time to keep it unblocked.

10. Adjust the light intensity not to exceed 20MA to prevent rapid aging of the laser tube.

11. Before starting work every day, the lens must be cleaned once.

12. Clean the reflector carefully on the machine, otherwise the optical path must be readjusted.

13. The third radiation mirror and focusing mirror must be removed and cleaned. After cleaning, the lens installation must be firm, but not too tight, so as not to break the lens.

14. Before each operation, please pay attention to the focal length. Inaccurate focal length will seriously affect the engraving effect.

15. After each operation, the work surface should be cleaned briefly. When cleaning, be careful not to fly dust.

16. Cleaning should be done after each operation. When doing cleaning work, when the power is cut off, you can gently push the beam and trolley, but it is strictly forbidden to push and pull violently.

17. Check the water protection switch regularly (once in half a month) to determine whether it is working normally.

18. Every other week, the guide rails must be cleaned, and lubricating oil should be added to the moving guide rails.

19. Every other week, clean up the peripherals of the machine (such as fans and air pumps).

20. After the machine works every day, it should be cleaned well. In the case of power failure, you can slowly push the focusing lens group and the X-axis guide rail seat, and it is strictly forbidden to push and pull violently. The bed body should be kept clean, especially the two linear guide rails. It is required to clean the oil stains on the guide rails and guide rail seats after work every day; transformer oil must be added to the linear guide rails and sliders before starting work the next day.
