50W Desktop Mini Fiber Laser Marking Machine
Equipment Introduction
◆ Desktop mini fiber laser marking machine uses laser beams to mark permanent marking on surfaces of various substances. The effect of the marking is to mark in the deep material through the evaporation of the surface material, thus engraving the exquisite designs, trademarks and texts. It can be used for marking logo, serial number, bar code and other beautiful patterns on any metallic materials such as stainless steel, titanium, brass, gold, silver, aluminum and lots of engineering plastic products such as mobile cover and charger, consume electronics housing and etc.

System Characteristics
◆ Fiber laser has excellent beam quality and high precision marking effect;
◆The whole machine is with compact structure design, small size, light weight, stable performance, high marking speed and repeat positioning accuracy;
◆ Core components are optimally designed with electromagnetic compatibility, with high signal-to-noise ratio and strong anti-interference ability;
◆ No need any maintenance for laser, and working lifetime is up to 100000 hours.

Knowledge
What is automatic focus?
Automatic focus laser marking machine working principle
After maintenance or replacement of the laser marking device, due to changes in the position, the distance between the lens and the workpiece changes, thereby appearing that the focus is not precise. On that condition, because the focus of the laser is not aligned on the surface of the workpiece, it will result in out of focus, thus making the marking effect unclear.
Automatic focus laser marking machines achieve automatic focus labeling through a visual location system, not required to physically move workpiece or laser marking machine. The focal length can be adjusted automatically, and the automatic tracking marking can be realized even if the thickness is fine. Not only can it reduce workload, but also significantly improve the quality of the product marking. And the operation is simple and convenient.
The principle is based on the basis of the traditional marking machine. It uses the high-precision CCD camera to capture the current location of the product, and transmits the location information of one or more products collected in real time, to the marking board through the software, thereby implementing accurate marking.
