When it comes to modern laser technology, speed and accuracy are essential. One of the core components that ensures both in laser marking and engraving systems is the galvo head. Whether you’re in industrial manufacturing, jewelry design, or electronics, understanding how a galvo head works and what makes it so valuable can help you make better decisions when investing in laser machinery.
What is a Galvo Head?
A galvo head, short for galvanometer scanning head, is a device used to direct laser beams with exceptional speed and precision. It typically includes two mirrors attached to motors—one for the X-axis and one for the Y-axis. By adjusting the angle of the mirrors, the galvo head steers the laser beam to a specific location on the work surface without moving the laser source or the object itself. This setup significantly enhances marking speed and positioning accuracy.
Why is the Galvo Head Important?
Speed is where the galvo head shines. Traditional CNC or moving-head laser systems must physically move the laser or the material, which slows down production. With a galvo system, the beam moves via mirror deflection, meaning it can operate at lightning-fast speeds—ideal for high-volume manufacturing lines.
Moreover, galvo heads enable non-contact marking, reducing wear and tear on machinery and offering greater consistency. The resulting marks are crisp and accurate, even on delicate or heat-sensitive materials.
Applications in Industry
Galvo heads are widely used in industries that demand precise, high-speed laser processing. These include:
-
Electronics: Marking serial numbers, barcodes, and micro-text on circuit boards.
-
Medical devices: Engraving identification on surgical instruments.
-
Automotive: Labeling parts and components with detailed logos and safety information.
-
Jewelry and fashion: Creating intricate designs and personalization.
Because of their speed and efficiency, galvo head systems are ideal for integrating into automated production lines.
Choosing the Right Galvo Head System
When selecting a laser marking system, the quality and performance of the galvo head play a vital role. Consider factors such as mirror size, motor response time, cooling methods, and compatibility with your laser source (fiber, CO₂, UV, etc.).
