The use Effect of alumina black laser marking machine has always been a hot topic in the marking industry. Many people say that the laser marking machine is fast and efficient, and the pattern is clear and exquisite. So it is very popular. Like Apple mobile phone shell, the mark on the keyboard, lighting industry and so on. Alumina black laser marking electromechanical light conversion efficiency is high, the output beam quality is good, this is beyond doubt. However, there are also a small number of people in the marking time, the alumina is not black enough to change the black, the white is not white enough, etc. , in fact, this is mainly caused by improper manual operation. The following is to share with you the experience and skills of alumina blackening laser marking machine! First of all, we have to understand what factors will affect the use of laser marking machine, the main factors affecting the fiber laser marking machine is divided into internal factors and processing the workpiece two factors. 1. Laser spot size: the smaller the spot, the smaller the marking volume. Therefore, the larger the spot, the faster the marking speed. 2. Marking format: Because the deflection area of the large-format marking mirror is increased, the marking speed of the large-format marking is slower than that of the small-scale marking. 3. Marking density: under the condition of the same size, the same light spot and the same depth, the higher the marking density, the slower the corresponding marking speed, the reason is that the density directly increases the marking area. 4. Marking depth: according to the requirements, if the marking depth needs to be 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, therefore, the marking speed will be affected in these processes. Secondly, the correct operation method of alumina laser marking machine: 1. Aluminum will not be stable during processing due to its material, so the setting of machine parameters is the most important. Different models of our company will have specific marking parameters in the manual. 2, for the initial use of alumina laser marking machine, in the irregular workpiece processing, must first carry out the red light positioning, to determine whether the processing position is accurate, otherwise 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, affecting the processing quality. When processing the workpiece, the smoke exhaust and smoke blowing equipment must be turned on to avoid dust pollution focusing lens and reflective lens, otherwise it will affect the lens focusing and reflection, thus indirectly affecting the processing strength and accuracy. 4. When the alumina laser marking machine carries out laser resistance scribing, there is a characteristic of metal mixture in the patch resistance material, and less metal residue is required after laser scanning, so during processing, to completely cut off the resistance, the bottom layer should be free of metal residue, electroplating should not touch tin. 5. When processing plastic workpieces, pay attention to the characteristics that the material is sensitive to light and easy to change color and easy to burn, which requires the operator to pay close attention to the processing speed and processing strength to avoid being too slow, if the intensity is too high, a flame will be generated. The flame will damage the focusing lens, and the processing intensity and processing precision will be slightly affected. Serious machines will not be used.
