What are the dimming and focusing steps of the laser marking machine?

In general, the focus setting on the laser marking machine is an important factor to obtain the best marking effect. The focus setting refers to the distance between the head of the laser machine and the material to be engraved. So, what exactly are the steps of such a process? Please let me introduce that to you in the following contents.

What is laser marking?

Laser marking is a kind of revolutionary technology that has been regarded as a new generation of processing fields, and laser marking machines based on that technology have been widely used in marking metal and non-metal parts. The core advantages of a laser marking machine are that it leaves no scratches, has a long life, and high precision. The advanced structure of the machine ensures the reliability of the laser source and the machine itself. The electro-optical transmission rate is high, which can save the operating cost of the machine. The marking speed is fast and can be customized according to customer requirements.

How does a laser marking machine dim and focus?

Generally, there are four types of dim and focus mode, the first kind is sonar mode. It is an automatic focus mode that does not require you to use a focus tool. Instead, you can press the Z positioning key on the laser marking machine, and then the ultrasonic sensor on the laser head will detect the surface of the workpiece. The focus is automatically calculated, and the Z-axis of the laser marking machine will move to the appropriate position. Sonar mode provides the highest accuracy and can focus on every position of the workbench. This highly accurate focus mode allows you to easily use the correct dim and focus on the laser marking machine every time. The second one is the light bar focus mode. If you are using flat, opaque objects or materials of unknown thickness, Lightbar focus is the ideal choice. This mode works by using sensors installed horizontally in the cabinet. You enable this focus mode on the keyboard of the laser engraving machine, which will automatically move the processing table upwards until the sensor detects the engraving material and calculates the correct focus. Software focus is another kind of automatic focus mode, the software installed in the computer control of the marking machine includes a function that can calculate the best focus point when you enter the material thickness and the lens used. The software has a two-way connection with the laser marking machine, which can sense the exact height of the worktable. After entering the information into the software, the workbench can be moved to the correct position by automatic adjustments. This is the ideal focus mode for processing materials of known thickness.
