What are the common reasons for the unstable power of laser marking machines?

There are many types of laser marking machines on the market, and the power is also different. For example, CO2 laser marking machines have laser powers of 10W, 20W, 30W, 50W, etc., and the power of the whole machine is 700W, 1000W, etc. Of course, there are also laser marking machines, UV laser marking machines, fiber laser marking machines, CO2 laser marking machines, etc.

Understanding the simple problem of laser marking machine power reduction and the corresponding solution is a skill that the maintenance personnel of the company’s CO2 laser marking machine must have. More reasonable operating specifications are also a guarantee for manufacturing excellent products.

Laser marking machines are professional industrial processing equipment. They have been used for a long time and are prone to some unexpected situations. For example, many users find that the power of laser marking machines is unstable. Here are eight common reasons for the instability of laser marking machines:

1. The marking speed is too fast.
Solution: Slow down the marking speed appropriately.

2. The voltage of the laser power supply drops, causing the laser output power to drop.
Solution: The power supply needs to be replaced.

3. The optical path system is inaccurate.
Solution 1: Adjust the laser.
Solution 2: Adjust the position of the beam expander. The incident light should be located at the center of the beam expander aperture, and the outgoing light should be located at the center of the exit hole.

4. The workpiece surface is not on the focal plane.
Solution: Adjust the workpiece surface to the focus.

5. The position and direction of the beam mirror are inaccurate.
Solution: Adjust the position of the beam expander.

6. The laser entering the galvanometer is off-center.
Solution: Adjust the laser.

7. The lens and lens are stained.
Solution: Clean or replace.

8. The service life of the equipment is long.
Solution: Inflate or replace a new laser.

As the largest component of laser equipment applications in my country, laser marking machines cannot be ignored in production and processing. Therefore, any potential problem will cause a loss of corporate benefits. The maintenance and repair of laser marking machine equipment is very necessary. The decrease in the power of the laser marking machine will lead to poor processing technology and make the processing effect fail to meet industrial requirements. Analyzing and solving this reason is a crucial task in processing operations.
