Laser marking machines are important in industries like manufacturing, automotive, and electronics. They create permanent, precise marks on different materials. CNC technology has made these machines more precise, flexible, and quick, making them popular for various tasks.
CO2 laser technology is now used to mark non-metallic parts, replacing traditional methods like CNC milling. This technology is user-friendly, quick, and precise. This article explains the features, uses, and benefits of Galvo CO2 laser marking machines and CNC CO2 laser engraving machines. It helps users choose the right machine for their needs.
Explore Galvo CO2 Laser Marking Machines
1. Definition and Working Principle
Galvo CO2 laser marking machines are advanced tools that engrave and etch non-metallic materials using advanced technology. These machines work by turning a mix of gases, such as CO2, Helium, Xenon, nitrogen, hydrogen, and water vapors, into a laser beam.
This happens through a process called gas discharge, which is triggered by AC or DC current. The laser that’s created gives off infrared light and goes into the material, creating heat. Helium helps remove this heat, while Hydrogen and water vapor change any carbon monoxide created back into carbon dioxide.
2. Types, Applications, and Features
Galvanometer CO2 laser markers are fast engraving machines. They can create detailed markings on lighter materials such as paper, acrylic, leather, and denim. These machines use CO2 metal or glass tubes. Additionally, they have a significant distance between the laser head and the workpiece, typically ranging from 25cm to 50cm.
They use CO2 metal or glass tubes and have a significant distance between the laser head and the workpiece (25cm-50cm). These machines are very fast, reaching speeds of 10000mm per second. They are great for branding on different materials like ceramics, glass, rubber, and paper. They don’t make deep cuts, so the results are clear and accurate.
3. Advantages and Disadvantages
Versatility: Marks a wide array of non-metallic materials.
Precision: High precision and detail, ideal for intricate designs.
Speed: Fast marking speeds enhance production efficiency.
Low Maintenance: Minimal maintenance compared to other technologies.
Surface marking only: The machine can only mark the surface of the material permanently; it can’t perform deep engraving or cutting.
Initial Cost: Higher initial investment compared to alternative solutions.
Limited marking area: The marking range is limited, usually only 110mm x 110mm, and the maximum does not exceed 300mm x 300mm

CNC CO2 Laser Engraving Machines Unveiled
1. Definition and Working Principle
CNC CO2 laser engraving machines use a laser source and a gantry system, like galvanometer machines. They can have a metallic or glass tube. Stepper motors help the laser head move, and the laser goes through three mirrors onto the material with a lens.
These machines have a shorter distance between the workpiece and the laser head, about 3-5cm. This allows them to cut materials and engrave. These machines are good at working with materials like wood, acrylic, and glass. They are used in industries that need detailed engraving, like signage, arts and crafts, and manufacturing.
2. Features, Advantages, and Disadvantages
CNC CO2 laser engraving machines can cut up to 20cm deep. However, they are slower than galvanometer types. The speed of cnc marking machine ranges from 80-600mm per second. The working area of these machines varies depending on the wattage, with options available for different needs.
Despite being expensive, models like the BobsCNC E3 CNC Router Engraver Kit offer great value. They provide precise cutting and engraving, especially on wood. Additionally, they are compatible with various platforms, allowing for enhanced customization. They are also compatible with different platforms for improved customization..
3. Advantages and Disadvantages
Detail and Precision: Renowned for creating highly detailed and precise engravings.
User-Friendly: CNC Marking technology ensures easy operation and design flexibility.
Large Engraving Area:The main feature is the large engraving area, usually from 600mm x 400mm and larger.
Versatility: Capable of marking, engraving, and cutting, enhancing its utility.
Material Limitation: Primarily effective on non-metallic materials.
High maintenance requirements: The water cooler of this machine requires frequent water changes and maintenance.
Initial Investment: The acquisition cost can be higher than some alternatives.
Slow engraving：The process has a slower engraving speed and necessitates a certain duration to complete.

Galvo CO2 Laser Marking Machines vs CNC CO2 Laser Engraving Machine: How to Choose?
Speed: Galvo CO2 laser marking machines are typically faster than CNC CO2 laser engravers. The galvanometer system in these machines allows for high-speed marking, making them ideal for mass production.
Precision: Both machines offer high precision, but the level of detail achievable with a CNC CO2 laser engraver can be higher. This makes CNC engravers more suitable for intricate designs.
Ease of Use: CNC machines often require more setup and preparation time than Galvo machines. However, once set up, they can run for long periods without supervision. Galvo machines, on the other hand, are generally easier to operate and require less setup time.
Versatility: CNC CO2 laser engravers excel in cutting and engraving a variety of materials. Galvo CO2 laser markers, while working on the same materials, are primarily used for quick and precise marking or etching.
Cost: CNC machines are usually more expensive than Galvo machines. However, the exact cost will depend on the specific models being compared.
Maintenance: Air-cooled CO2 laser markers need less maintenance than water-cooled CNC CO2 laser engravers, which may reduce long-term expenses.
The Galvo CO2 laser marking machine is ideal if your priority is batch marking and speed and efficiency. The CO2 cnc laser marking machine is a recommended choice for large area marking, deep engraving, and some cutting. To make the best choice and get the best results, it’s important to fully understand each machine’s strengths, advantages, and limitations.
