Laser technology has become the cornerstone of advanced industrial manufacturing, and one component stands out for boosting efficiency and accuracy — the Galvo Head. At LaserChina, a global leader in laser systems, the integration of high-quality galvo head into their laser marking and engraving machines brings unmatched performance to industries like electronics, automotive, medical devices, and more.
This guide dives deep into how galvo heads work, why LaserChina’s systems are uniquely optimized, and what you need to know to choose the right solution.
What Is a Galvo Head?
A Galvo Head (short for galvanometer scanner head) is a precision device used in laser marking, engraving, and cutting systems. It consists of two mirrors controlled by galvanometers — motorized devices that move the laser beam across an X-Y plane with incredible speed and accuracy.
Core Functions of a Galvo Head:
Rapid Beam Steering: The galvo system controls the beam direction using highly responsive motors.
Precision Movement: Galvos offer pinpoint accuracy for detailed laser etching and fine cuts.
Non-Contact Marking: No mechanical movement of the part, reducing wear and increasing uptime.
Why Galvo Technology Matters in Laser Marking
Laser marking applications demand speed, consistency, and low maintenance. Galvo heads enable laser systems to deliver:
Higher Throughput: Faster marking cycles boost productivity.
Improved Accuracy: Consistent beam positioning ensures quality.
Lower Operational Costs: Less mechanical wear means reduced maintenance.
At LaserChina, galvo heads are engineered to align with advanced software control and fiber laser sources, ensuring seamless operation across materials like metal, plastic, ceramics, and composites.

FAQs About Galvo Heads
What makes a galvo head different from a CNC system?
Unlike CNC machines, which rely on mechanical movement, galvo heads direct the laser via mirrors — resulting in faster, frictionless operation.
Can I replace the galvo head myself?
LaserChina offers modular galvo head units, but replacement should be done by trained personnel to ensure calibration integrity.
Are galvo heads compatible with fiber lasers only?
No. They are compatible with fiber, UV, CO₂, and green lasers depending on the application.
What maintenance does a galvo head require?
Minimal. Periodic cleaning of mirrors and ensuring proper cooling is generally sufficient.
Does the galvo head affect marking depth?
Not directly. Depth is influenced more by laser power and dwell time, though galvo speed affects exposure time and surface detail.
Final Thought
The galvo head is a pivotal component in today’s laser systems, especially when paired with the expert engineering and robust design of LaserChina. Whether you’re upgrading your marking line or launching a new product, understanding and leveraging the capabilities of galvo technology can elevate your manufacturing process to world-class standards.
