A Guide to Troubleshooting Common Problems in Micron-Level Marking

During the micrometer-level marking process, there are often problems with the accuracy of the laser, equipment malfunctions, or incompatibility with the material.These solutions include laser parameter calibration, equipment maintenance and material matching skills, and help customers quickly identify the root of problems, and improve efficiency and product quality.

What if the marking isn't accurate enough?

Check laser status.

If the laser line is blurred or off center, check the lens for dust or dirt.Use a clean cotton swab dipped in alcohol to gently wipe the surface. Don't use ordinary toilet paper, because it is easy for it to leave bits of paper on the surface.

Adjusting parameters.

If the speed is too high or the power too low, the result can be a "shrinking" of the label.Try setting the power at about 80 % of the recommended value, and the speed at 20 % less, and try again.Remember that different materials (such as metal and plastic) require separate parameter templates.

The machine suddenly reported an error.

The problem of heat dissipation.

In summer, overheating is the most common problem. Check to see if the equipment is too hot to touch.When you turn off your computer, clean the fan filter. If you are going to work for more than four hours, take a break for 15 minutes to let the machine "catch its breath.

Check the stability of the power supply.

Unstable voltage can cause the control unit to crash.Try connecting it to a voltage stabilizer, especially if you are using it in an old factory building where the voltage fluctuates a lot.I once had a customer whose equipment was being interfered with by the arc welder in the next room, causing it to shut down and restart. Adding an isolation transformer solved the problem.

The surface effect of the material was not good.

Preparation is very important.

Is it possible to get color differences when marking stainless steel? First, use alcohol to clean the surface of the material. Don ’ t underestimate the influence of fingerprints and oil films. They will increase the reflectivity of the laser.If the material is reflective, such as aluminum oxide, then the effect of a special marking film is immediate.

(4) Adjust the focus.

Don't just stick to the standard focal length in the manual. Use a scrap piece of material to do a step test, adjusting the focus by 0.2 millimeters each time, to find the clearest focus.In particular, curved surfaces are much more reliable with autofocus than with fixed-focus.

Daily maintenance tips.

Every weekend, he spends ten minutes doing three things: using an air gun to blow away metal dust from the rails, adding a little lubricating oil to the lead screw, and checking whether the optical lens has become loose.It's much cheaper to develop good habits than to wait for things to break and then repair them.
