Why does the laser of the laser engraving machine become weaker than before?

As a processing equipment using laser as energy source, laser engraving machine's stability directly affects the processing capability. Whether the equipment can be used normally depends entirely on whether the laser tube can output normal intensity laser. There are many reasons for the weakening of the laser, some are caused by external factors, and some are caused by the laser tube itself. Today, Leapion Laser will give you an analysis. Why does the laser of the laser engraving machine become weaker and weaker? And the corresponding solution.

If it is found that the laser of the laser engraving machine is getting weaker and weaker, we can investigate the reasons from the following 9 points and solve them one by one:

1. Check whether the focusing lens is contaminated:

Solution: Clean the focusing lens.

 

2. Check whether the focus focal length has changed:

Solution: re-adjust the focus.

 

3. Check whether the light path is offset:

Solution: carefully adjust the light path.

 

4. Check if the reflective lens is contaminated or damaged:

Solution: Clean or replace the reflective lens.

 

5. Check whether the laser power supply is energized:

Solution: Check the laser power supply circuit to make it normal.

 

6. Check whether the laser tube is damaged or aging:

Solution: Replace the laser tube.

 

7. Check whether the laser power supply is damaged:

Solution: Replace the laser power supply.

 

8. Check whether the temperature of the laser engraving machine is too high:

Solution: replace the cooling water

 

9. Check whether the cooling water is circulating:

Solution: dredge the cooling water circuit.

 

10. Check whether the cooling water quality or water temperature is constant:

Solution: Replace Haojie cooling water to bring the temperature to normal value.

Advantages of laser engraving machine:

1. Laser engraving can automatically skip numbers, has strong anti-counterfeiting function, and has exquisite pictures and texts, fine lines, cleaning and abrasion resistance.

 

2. Environmental protection, energy saving, no pollution, no toxic substances, easy to pass the RoHS standard, easy to produce.

 

3. Material saving: Laser processing adopts computer programming, which can cut products of different shapes, maximize the utilization rate of materials, and greatly reduce the cost of materials for enterprises.

 

4. Accurate and meticulous: The thinnest line width of laser engraving on the surface of the material can reach 0.015mm, and the width of the laser cutting incision is generally 0.1~0.5mm. The welding is cold welding and the weld is flat, and there is no heat-affected zone.

 

5. Small thermal deformation: The laser beam of the metal marking machine is thin, fast, and energy concentrated, so the heat transferred to the processed material is small, and the material deformation is also very small.

 

6. Good finish of the processed surface. Laser engraving machine can greatly shorten the development cycle of new products.

 

Compared with traditional processing methods, laser engraving machines have higher production efficiency and quality. If there is a problem in the processing process, it will directly affect our production efficiency. This requires us to quickly and accurately determine the cause in order to solve it as soon as possible and resume production.
