3 Axis CO2 Laser Marker
CO2 laser markers use a lasing medium containing carbon dioxide, nitrogen, hydrogen, and helium to generate the laser beams. They are generally slower than fiber lasers and are better suited for organic materials.
CO2 laser marking machines can mark a wide variety of organic materials. They also offer high marking speeds and precise markings. They can also be used to mark slanted and curved surfaces.
Power
When it comes to laser marking, a CO2 marker is an excellent choice. These machines can engrave a wide variety of materials and can produce a high-quality mark that won’t smudge or fade over time. They can also be used to etch or cut thin foils, paper and wood. They are a great option for manufacturers looking to save money on maintenance and repair costs.
A CO2 laser uses a gaseous medium of carbon dioxide, nitrogen and hydrogen to produce invisible laser light. This light is in the far infrared spectrum and is safe for use on most materials, but it is not suitable for marking metals. In contrast, fiber lasers have a shorter wavelength and are more efficient than traditional CO2 models.
CO2 lasers are typically powered by a large laser tube. These tubes are water-cooled and contain a mixture of gases that act as an optical resonator system. When energized by an electric discharge, the nitrogen molecules are raised to excited states and form photons that generate light energy. This process is known as population inversion.
Wavelength
CO2 laser markers are powerful marking systems that can be used to engrave a variety of products and surfaces. They can mark both opaque and transparent objects, such as glass and plastics. They can also be used for etching. They can even be used to create 3D marks on non-flat surfaces, such as cylinders and slopes. But, before you invest in one, it is important to understand what these systems can do and how they work.
The wavelength of a CO2 laser marker is between 9.3 and 10.6 m. This wavelength pairs well with the absorption spectrum of polymers, natural materials like paper and wood, and certain metals. In contrast, fiber and YAG lasers have shorter wavelengths and are better suited for marking metals.
The laser marking process works by directing the laser beam to a product using mirrors mounted on galvanometers. The galvanometers are connected 3 axis co2 laser marker to a multi-element, flat-field lens assembly that focuses the beam to achieve high power density on a flat surface. This type of marking is often used for barcodes, logos, and other graphics on various products.
Cost
If you’re planning to purchase a 3 axis co2 laser marker, the cost is an important consideration. You’ll want to compare prices between the different manufacturers to ensure that you’re getting the best price.
Generally, CO2 laser markers are less expensive than fiber lasers. However, the maintenance costs can be a significant co2 laser marking machines factor in the overall cost. CO2 lasers require a cooling system, which adds to the overall cost of the machine. Fiber lasers don’t need a cooling system, which makes them more affordable.
The ML-Z series of laser marking machines is particularly impressive, as it can mark both opaque and transparent materials in three dimensions. This capability allows the laser to be used on a variety of surfaces, including slopes and stepped shapes, which eliminates product damage. It also simplifies product and tool changeovers. In addition, the 3-axis scanner head can change focal distance rapidly, allowing for more precise marks. This feature can be particularly useful in applications that require a lot of repetition.
Lifespan
The lifespan of a 3 axis co2 laser marker depends on the type of material and engraving style used. For example, a high-powered laser will typically last longer than a lower-powered model. This is because the higher-powered laser can produce more energy and etch deeper into the material.
The lifetime of a co2 laser marking machine is also dependent on the quality of the emitter. For this reason, it’s important to buy a machine that uses only trusted emitters. In addition, it’s recommended to choose a company that provides a warranty on the equipment and ensures that the emitter is correctly adjusted upon delivery.
KEYENCE’s range of laser markers allows you to mark on a variety of different materials and create unique identification tags. This allows you to track and trace your parts, ensuring their safe and efficient shipping. In addition, the system can automatically adjust for X, Y and theta offsets so that it marks in the exact same location on each part. This reduces scrap and rework and saves you money. Moreover, the MD-X Series offers a variety of additional features such as a camera inside the laser marking head and an automatic calibration system to eliminate product defects.
Maintenance
The maintenance needs of a 3 axis co2 laser marker vary depending on the frequency and duration of use. You should always follow the directions in the manual that came with your system to ensure optimal performance. The X-axis rail guides and the 4 bed screws need to be cleaned and lubricated periodically. This will help prevent premature wear. You should also clean the focusing lens frequently to keep it free of dust.
The quality of the circulating water directly affects the life of the laser tube. You should use distilled water and maintain the water temperature below 35 degC. It is also important to clean the water tank and replace it with fresh circulating water.
Another common problem is a contaminated quartz tube, which can rob the laser of power. To prevent this, Donner recommends shining a flashlight up inside the laser beam delivery system. You should also check the gaskets and bellows for any leaks. If you find a leak, you should replace them immediately. Moreover, you should clean the resonator and the laser gas bottles every week to avoid contaminating them with smoke.
