Advantages of laser marking machine
1. Marking durability: Laser marking is essentially a “destructive removal” process. The marked marks are not easy to imitate and change, and the marks will not be affected by the environment (touch, acidic and alkaline gases, high temperature, low temperature, etc.) and subsided.
2. Non-contact processing: laser marking is processed by non-mechanical “”light knife””, which can print marks on any regular or irregular surface, and the workpiece will not generate internal stress after marking, ensuring the original quality of the workpiece. There is precision.

Laser processing mode:
The focused laser is like an extremely fine invisible tool, which vaporizes the surface of the local area of the object point by point. It is characterized by non-contact processing and does not contact the workpiece. Mechanical extrusion or mechanical stress will not change the physical properties of the processed items; due to the small size after laser focusing, the small heat-affected area, and the fine processing, some processes that cannot be achieved by conventional methods can be completed.

The basic principle of laser marking machine:
The laser emitted by the laser undergoes a series of treatments, and after being focused by the lens, the energy is highly concentrated in a small range, so that the surface material is instantly melted or even vaporized, and the required image is formed by controlling the path of the laser on the surface of the material. Text mark. Depending on the material properties, the workpiece will undergo a series of physical or chemical changes, such as melting, vaporization, oxide formation, discoloration, and so on. This is how laser processing works

Maintenance of the marking machine:
1 The laser, the surface of the Q-switch crystal, the beam expanding part, and the focusing lens must be cleaned regularly. (Wipe with lens tissue or cotton ball with a little cleaning solution every other month, do not wipe too hard)
2. Master the correct operation method of the marking machine.
3. After use, clean and organize the work surface in time.

Maintenance of the marking machine:
1. Keep the water clean: Change the water every 20 days on average, and the water tank must be cleaned before changing the water (this machine uses deionized water, distilled water, drinking pure water)
2. When starting the machine, you must check whether the water flow is normal. (The water pipe should not be broken, and there should be no leakage at the interface)
3. The circulating water is within a certain temperature range. (Generally set between 24°C and 28°C, and the indoor temperature is within 30°C)

Parameter description of laser marking machine
1. Graphic Filling Spacing – Control the degree of solidity in the marking graphics. The smaller the graphic spacing, the denser the filling, and the closer the graphic is to a solid. Of course, the more lines there are, the longer the processing time will be. vice versa.
2. Fill angle – control the direction of the fill line and determine the texture in the graphic. Common fill angles are: 0 or 180 degrees; 90 degrees; 45 degrees; 135 degrees

Detailed description of laser marking machine parameters
1. Laser power supply current – control the laser power value output by the laser. The higher the current value, the higher the laser power.
2. Frequency – control the peak power of the laser and the number of laser pulses per unit time. The larger the frequency value, the smaller the peak power and the more laser pulses per unit time.

A good high-speed galvanometer can scan tens of thousands of times per second, but in general, the scanning speed of the galvanometer can reach up to 3000mm/s. Different galvanometers have different effects on the marking effect and speed. If you want to improve the marking It is generally recommended to choose a better high-speed galvanometer to improve efficiency.

Choose the most suitable filling method to improve marking efficiency:
1. Two-way filling: the marking efficiency is the best, and the effect is good
2. Back-shaped filling: it is only used when marking thin graphics and fonts, and the efficiency is similar to that of bow-shaped filling
3. One-way filling: the marking efficiency is the slowest, and it is rarely used in actual processing
4. Bow filling: The marking efficiency is the highest, and sometimes there will be problems of connecting lines and unevenness. When marking thin graphics and fonts, the above problems will not occur, so the bow filling is the first choice.

Factors affecting the effect and speed of laser marking: First of all, for a fixed marking pattern, the factors affecting the marking efficiency can be divided into the equipment itself and processing materials. Therefore, it can be concluded that factors such as filling type, field mirror, galvanometer, and time delay that ultimately affect the marking efficiency.
