CO2 Laser Machine

A CO2 laser uses a stream of carbon dioxide to create a very intense light that can cut a wide range of materials when it is heated up to its ignition point. It uses the latest machining technology to guarantee precision work and a fast turnaround. CO2 laser engravers and cutters are highly precise and can be used to create designs, decorations, and the like on just about any material you can think of, including wood, plastic, metal, and paper to name a few.

Types of CO2 Laser Cutting

Melt and Blow

The laser beam will first heat the material until it has reached a liquid state. Then, a jet of high-pressure, non-reactive gas like nitrogen is used to blow the molten material out of the area being cut. This method allows for lower energy use to achieve the same cut depth.

Reactive Cutting

This process is generally used on materials that are easily oxidized, such as steel or titanium. The laser beam heats up a localized area, and a high-pressure stream of oxygen is directed onto this area. This oxygen essentially causes the metal to oxidize and burn. The metal oxides are then blown from the cut by the oxygen stream.

Vaporization Cutting

This process does not make use of any high-pressure gasses. It  relies solely on the heat energy from the laser beam to sublimate the material being cut. This means that the heat causes the material to transition directly from a solid phase to a gas phase. This process is only possible with materials that have low vaporization temperatures, like plastic.

Daily Maintenance Tips for CO2 Laser Machine

1. Change of Water and Water Tank Cleaning

Note: the machine work before must ensure that the laser tube is full of circulating water.

Circulating water quality and water temperature directly affects the service life of the laser tube, it is recommended to use pure water and to control the water temperature below 35 degree Celsius. For more than 35 degree Celsius to replace the circulating water, or to add ice to reduce the water temperature, water (cooling machine, suggest the user select or use two-tank).

Clean water tank: first, turn the power off and remove water inlet pipe, let the laser tube of water into the tank automatically, open the water tank, pump and clear the dirt on the water pump. Good clean water tank clean, replace the circulating water, the water pump to restore back into the water tank, the connection pipe inserted into the inlet of the pump, tidy up the joint. The pump power alone, and run 2 to 3 minutes (the laser tube is full of circulating water).

2. Cleanness of the Fan

After long time use, it can make the fan inside the accumulation of a lot of solid dust, let the fan make a big noise, in addition to flavor and is unfavorable to the exhaust. When appear insufficient suction fan smoke not free, turn off the power supply first, will be discharged into the duct and the duct on the fan, remove the inside of the dust, and then put the fan on, and pull out the inside of the blades, until clean, then put the fan installed. Then it can support the co2 laser machine well working.

3. Lens Cleaning

Machine is introduced in front, has talked about carving machine has three pieces of reflector and 1 piece of focusing mirror (1 reflector in the laser tube, the launch of the exit is at the upper left of the machine, the reflector is in the left side of the beam’s #2 and #3 mirrors in laser head on top of the fixed part, is located in the lower part of the laser focusing mirror adjustable lens barrel), after focusing laser is through the lens reflex, emitted from a laser. Lenses can easily touch dirt or other contaminants, cause loss or damage of lens of laser, no. 1 and no. 2 don’t must be removed, while the lens cleaning need to dip in cleaning fluid to clean lens paper carefully wipe up along one edge of the lens central to rotary. No. 3, lens and focus lens from the frame, in the same way, to wipe, wipe after the completion of the same back then.
