A Guide: Everything About Galvo Scan Heads For Laser Marking and Engraving

Galvanometer scanner systems, or as they are commonly known, galvo heads, are pivotal in laser marking and engraving due to their ability to rapidly and accurately steer laser beams over a material's surface. Its working process begins when a computer sends the desired design to the galvo head, which is then converted into analog signals directing the galvanometer motors. These motors, equipped with mirrors on their shafts, redirect the laser across the X and Y axes, resulting in precise marks or engravings on the material. The efficiency and quality of the marking or engraving significantly depend on the speed and precision of the galvo head.

Application of Galvo Scan Heads

In today's ever-evolving technological landscape, the swift and precision-driven capabilities of galvo heads are playing an increasingly influential role across various sectors. Here are some of its most common applications:

Product Identification and Branding

Companies are leveraging laser marking more than ever to make their unique brand identity. Galvo scan heads are commonly utilized in laser marking and engraving systems. They facilitate swift movement and exact laser beam positioning, creating intricate designs, serial numbers, barcodes, and other markings on materials such as metals, plastics, and ceramics.

Scale Marking

Scale marking is another important application of galvo scan heads. Galvo scan heads are used for accurately and precisely marking scales, graduations, and measurements on various surfaces. Precision tools and instruments, such as measurement rulers or intricate dials on advanced machinery, demand absolute marking accuracy. Galvo heads are extremely useful in such tasks that they are used in a wide range of applications in instrumentation, aerospace, automotive industry, optical equipment, and other areas.

Art and Craft Engraving

Galvo heads have found an excellent application in art and craft engraving. Their ability to render intricate designs on diverse materials like wood, glass, metals, and beyond has transformed traditional engraving methods. Also, in 3D printing applications, galvanometer scanning heads facilitate the creation of three-dimensional objects by facilitating precise layer-by-layer laser curing or sintering in 3D printing applications.
