A galvo scanner laser engraver has many benefits over a conventional XY axis laser cutter, which moves the laser head along an X and Y axis (side to side, and backward and forward) in a similar manner as an inkjet printer. A galvo scanner laser engraver can achieve much higher speeds, accuracy, quality, flexibility, and cost-effectiveness than an XY axis laser engraver. A galvo scanner laser engraver can also be controlled by software and camera systems that make project setup and alignment easy and precise.

A galvo scanner laser engraver has many applications in different industries that require metal marking or engraving. For example, a galvo scanner laser engraver can be used to create unique and customized designs on jewelry, medical devices, automotive parts, aerospace components, etc. A galvo scanner laser engraver can also be used to create functional marks such as barcodes, QR codes, serial numbers, logos, etc.

In this article, we will explain how a galvo scanner laser engraver works, what are its benefits over a conventional XY axis laser engraver, and what are some of its applications in different industries. By the end of this article, you will have a better understanding of what a galvo scanner laser engraver can do for you and your business.

How Does a Galvo Scanner Laser Engraver Work?

A galvo scanner laser engraver works by using a galvanometer system to deflect the laser beam with a mirror or a mirror array. A galvanometer is an instrument that detects or measures a small electric current by movements of a magnetic needle or a coil in a magnetic field.

A galvanometer was originally invented in 1820 by Hans Christian Oersted, who discovered that a magnetic compass needle would deflect when it was near a wire with an electric current running through it. A galvanometer was later used for long-range communications, such as the TransAtlantic Telegraph underwater cable system. A galvanometer was also used for medical purposes, such as measuring the electrical activity of the heart and the brain.

A galvo scanner laser engraver uses a galvanometer to control the angle of the laser beam by rotating the mirror or the mirror array. The mirror or the mirror array is driven by servo motors that respond to the electric current from the galvanometer. The laser beam is then focused by a lens onto the metal surface.

By changing the angle of the mirror or the mirror array, the laser beam can move rapidly across the metal surface without moving the workpiece or the laser head. This allows the laser to create various types of marks on the metal surface, depending on the power, speed, frequency, and pulse width of the laser.

A galvo scanner laser engraver can be controlled by software and camera systems that make project setup and alignment easy and precise. The software allows you to design your project in almost any software program, such as AutoCAD, Bartender, Adobe Illustrator, or CorelDRAW. You can then print your file to the software, position your artwork with the camera system, and choose your engraving settings. The camera system consists of two cameras above the work area that automatically adjust for the installed lens. The camera system allows you to drag and drop your artwork on screen, choose your engraving settings, and send the file to the laser in seconds.

What are the Benefits of Using a Galvo Scanner Laser Engraver?

A galvo scanner laser engraver has many benefits over a conventional XY axis laser engraver in terms of speed, accuracy, quality, flexibility, and cost. Here are some of the benefits of using a galvo scanner laser engraver:

Speed

A galvo scanner laser engraver can achieve much higher speeds than an XY axis laser engraver because it does not need to move the workpiece or the laser head. A galvo scanner laser engraver can move the laser beam at speeds up to 36,000 mm/min, while an XY axis laser engraver can only move at speeds up to 1,000 mm/min. This means that a galvo scanner laser engraver can complete a project in minutes or seconds, while an XY axis laser engraver can take hours or days.

Accuracy

A galvo scanner laser engraver can achieve much higher accuracy than an XY axis laser engraver because it can control the angle of the laser beam with precision. A galvo scanner laser engraver can create marks with a resolution of up to 0.05 mm, while an XY axis laser engraver can only create marks with a resolution of up to 0.1 mm. This means that a galvo scanner laser engraver can create finer and sharper details on metal surfaces than an XY axis laser engraver.

Quality

A galvo scanner laser engraver can achieve much higher quality than an XY axis laser engraver because it can create various types of marks on metal surfaces with different effects. A galvo scanner laser engraver can create deep engraving marks that remove material from the metal surface, polished white marks that reflect light from the metal surface, black annealed marks that change the color of the metal surface without removing material, ablation marks that remove coatings or paints from the metal surface, texturing marks that create patterns or textures on the metal surface, etc. These types of marks can enhance the appearance and functionality of metal products.

Flexibility

A galvo scanner laser engraver can achieve much higher flexibility than an XY axis laser engraver because it can adapt to different types of projects and materials. A galvo scanner laser engraver can work with different types of metals, such as steel, stainless steel, aluminum, copper, brass, titanium, etc. A galvo scanner laser engraver can also work with different shapes and sizes of metal products, such as flat plates, curved surfaces, cylindrical objects, etc. A galvo scanner laser engraver can also work with different types of designs, such as logos, texts, graphics, barcodes, QR codes, serial numbers, etc.

Cost

A galvo scanner laser engraver can achieve much lower cost than an XY axis laser engraver because it can save time, money, and resources for different types of projects. A galvo scanner laser engraver can reduce labor costs by completing projects faster and easier than an XY axis laser engraver. A galvo scanner laser engraver can also reduce material costs by creating less waste and using less energy than an XY axis laser engraver. A galvo scanner laser engraver can also reduce maintenance costs by having fewer moving parts and requiring less calibration than an XY axis laser engraver.

FAQs

Here are some frequently asked questions about galvo scanner laser engravers:

What is the difference between a static galvo scanner and a dynamic galvo scanner?

A static galvo scanner is a type of galvo scanner that only moves the mirror or the mirror array in one direction (X or Y). A dynamic galvo scanner is a type of galvo scanner that moves the mirror or the mirror array in both directions (X and Y). A static galvo scanner is faster and more accurate than a dynamic galvo scanner. A static galvo scanner is more suitable for small area marking or engraving than a dynamic galvo scanner.
