How to improve the working efficiency of laser marking machine?

Factors affecting marking efficiency

China CO2 Laser Marking Machine Manufacturer,For a fixed marking pattern, the factors affecting marking efficiency can be divided into the equipment itself and the processing material. From these two factors, it can be subdivided into different aspects: the final factors affecting marking efficiency are the filling type, field lens (filling line spacing), galvanometer (scanning speed), delay, laser, processing materials and other factors.

Measures to improve marking efficiency

1.Select the appropriate filling type

Bow-shaped filling: the highest marking efficiency, sometimes there will be problems with connecting lines and unevenness. When marking thin graphics and fonts, the above problems will not occur, so bow filling is the first choice.

Two-way filling: The marking efficiency is second, and the effect is good.

One-way filling: the slowest marking efficiency, rarely used in actual processing.

Shape filling: It is only used when marking thin graphics and fonts. The efficiency is similar to that of bow filling.

2.Choose the right field lens

The larger the focal length of the field lens, the larger the focused spot; under the same spot overlap rate, the filling line spacing can be increased, thereby improving the marking efficiency.(China F-Theta Objective Lens Factory )

3.Choose a high-speed galvanometer

Ordinary galvanometer, the maximum scanning speed can only reach two to three thousand millimeters per second; high-speed galvanometer, the maximum scanning speed can reach tens of thousands of millimeters per second, effectively improving marking efficiency. In addition, when using ordinary galvanometers to mark small graphics or fonts, deformation is easy to occur, and the scanning speed must be reduced to ensure the effect.

4.set the appropriate delay

Different filling types are affected by different delays, so reducing delays that are not related to the filling type can improve marking efficiency

Bow fill and round fill: Mainly affected by the corner delay, it can reduce the turn-on delay, turn-off delay, and end delay.

Two-way filling and one-way filling: Mainly affected by the light-on delay and light-off delay, it can reduce the corner delay and end delay.

Bold graphics and fonts are less affected by the delay, and the delay can be appropriately reduced. Thin graphics and fonts are greatly affected by the delay, and the delay can be increased appropriately.

5. Choose the right laser

For the laser that can be used for the first pulse, adjust the height of the first pulse, and the turn-on delay can be zero. The conventional switching method of two-way filling and one-way filling can effectively improve the marking efficiency.(Laser Cutter, Engraver & Marking Machines factory )

Choosing a laser with independently adjustable pulse width and pulse frequency can not only ensure a certain degree of overlap after focusing at high scanning speed, but also ensure that the laser energy has enough peak power to reach the destruction threshold of the material and vaporize the material.

6.processing materials

For example: good (thick oxide layer, uniform oxidation, no wire drawing, fine sandblasting) anodized aluminum, when the scanning speed reaches two to three thousand millimeters per second, it can also produce very black effects; poor aluminum oxide, scanning speed It can only reach a few hundred millimeters per second. Therefore, suitable processing materials can effectively improve marking efficiency.
