The use of alumina laser marking machine has always been a controversial topic in the marking industry. Many people say that the laser marking machine is fast and efficient, and the pattern is clear and beautiful.
Alumina laser marking electromechanical light conversion efficiency, output beam quality is good, this is unquestionable. However, there are also a small number of people who are marking the aluminum, which is not black enough to be black, white is not white enough, etc. In fact, this is mainly caused by improper manual operation.
First of all, we need to understand what factors will affect the use of laser marking machines, the main factors affecting fiber laser marking machine are divided into internal factors and processing of the workpiece.
1. Marking format: Because the deflection area of the large-format marking galvanometer is increased, the marking speed of the large format is slower than the marking speed of the small format.
2. The internal factors are mainly laser frequency, laser spot mode and beam divergence angle, laser power, reasonable optical shaping and auxiliary gas during processing. The internal factors are mainly paid attention to when the previous models are selected, and should be purchased according to the opinions of the laser engineers. Another factor that needs to be paid attention to by the customer is mainly the marking density, the marking format, the marking depth and the laser spot size.
3. Marking depth: According to the demand, if the depth of the marking is deepened, the parameters of the fiber laser marking machine need to be adjusted to increase the power and current of the fiber laser marking machine, so in these processes, Affect the marking speed.
4. Laser spot size: The smaller the spot size, the smaller the marking volume. Therefore, the larger the spot, the faster the marking speed.
5, marking density: in the same format, the same spot, the same depth, the higher the marking density, the corresponding marking speed will be slower, the reason is that the density directly increases the marking area.
The correct operation of the alumina laser marking machine:
1. Due to the material, the aluminum material will not be stable during processing, so the setting of the machine parameters is the most important. Different models of our company will have specific marking parameters in the manual.
2. For those who use the alumina laser marking machine at the beginning, when processing irregular workpieces, it is necessary to first perform red light positioning to determine whether the processing position is accurate or not, otherwise it is easy to produce waste.
3. When the alumina laser marking machine is working, it is forbidden to open its cover (top cover and front cover), otherwise the laser emission will be stopped, which will affect the processing quality. When processing the workpiece, the smoke exhausting and blowing equipment must be turned on to prevent the dust from contaminating the focusing lens and the reflecting lens, otherwise the lens will be focused and reflected, which will indirectly affect the processing strength and precision.
4. When the laser laser marking machine of the alumina laser marking machine has the characteristics of the metal mixture in the chip resistor material, the metal residue is required to be less after the laser scanning, so when the processing is performed, the resistance should be completely cut off, and the bottom layer should be free of metal. Residue, do not tint the plating.
5. When processing plastic workpieces, pay attention to the characteristics of materials that are sensitive to discoloration and easy to burn. This requires the operator to pay close attention to the processing speed and processing strength, to avoid the flame being too slow due to too high speed, and the flame will damage the focus. Lenses, lighter impact on processing strength, processing accuracy, serious machines will not be available.
Combine the above points, I believe that everyone understands the correct operation of the alumina laser marking machine.
