Fiber Laser Markers

SJC Series Portable Handheld Laser Marking Machine

This product has a wide range of applications. It is suitable for standard metals and alloys (all metals such as iron, copper, aluminum, magnesium, zinc, etc.), rare metals and alloys (gold, silver, titanium), metal oxides (all kinds of metal oxides), special surface treatment (phosphating, aluminum anodizing, electroplating surface), and other materials. It can mark and engrave on common hardware tools, knives, kitchenware, metal jewelry, buttons, integrated circuits, packaging bottles, glasses frames. This marking machine can mark a clear, high resolution and provide long lasting markings on materials. The environmental requirements are simple and flexible and there is no special requirement on constant temperature and humidity, and water cooling to operate. This laser marking machine is small size, light weight, small footprint, and portable for online marking.

Product features:

• Accurate positioning: The scanning galvanometer adopts high-performance scanning devices and advanced photoelectric sensing technology. The differential photosensors can exactly detects the position of the motor rotor. It is with good linearity, has a small drift during operation, marks with high resolution and has a high accuracy on repeated positioning.

Application Notes:

• Marking field: Marking field depends on scan lens (f-theta lens) once other parameters and parts are confirmed. Large field sizes demand the use of lenses of long focal length. In turn, this leads to increase focused spot size and decrease laser power density on the workpiece. Thus reasonable mark field should be carefully selected. If both small focused beam diameter (narrow line width) and large marking field are simultaneously required, a XY moving table is recommended for best performance. However, there may be a little alignment along the junction edges of neighbour pisions since the moving accuracy and resolution are always limited.

• Focused beam diameter: The focused beam diameter is related to f-theta lens, beam expander and laser parameter (beam quality, beam diameter, beam pergence etc). Higher laser power always needs larger beam diameter and thus results in worse beam quality (such as larger pergence angle etc) and further results in larger focused beam diameter.

• Mark linewidth: in order to get narrow linewidth, 1) you may use the f-theta lens with smaller mark field and beam expander with larger beam expansion ratio. 2) You may increase beam quality by inserting an aperture inside laser resonator. 3) you may increase the marking speed.
