What is CO2 Laser Cutter?

CO2 laser cutter is a CNC laser machine that uses CO2 laser beam to engrave and cut wood, MDF, plywood, chipboard, dieboard, cardborad, acrylic, fabric, jeans, plastic, leather, paper, ABS, EPM, PE, PES, PUR, PVB, PVC, PUR, PMMA, PTFE and thin metals, which is widely used in industrial manufacturing applications, school education, small businesses, home business, small shop and home shop. A CO2 laser cutter is composed of laser cutter frame, laser cutting head, laser lens, laser mirror, laser generator, laser power supply, water chiller, control panel and CNC (Computer Numerical Controlled) system. CO2 laser cutter is also known as CO2 laser cutting machine, CO2 laser cutting system, CO2 laser cutting equipment, Non-metal laser cutting machine, CO2 laser engraver, CO2 laser engraving machine, CO2 laser engraving cutting machine.

How Does CO2 Laser Cutter Work?

CO2 laser cutting is to use a CO2 laser tube with a numerical control system to irradiate the laser beam to the surface of the object, and at the same time release high energy to melt and evaporate the surface of the object, thereby realizing the plan of cutting and engraving. The laser beam is a column of very high intensity light, of a single wavelength, or color. In the case of a typical CO2 laser, that wavelength is in the Infra-Red part of the light spectrum, so it is invisible to the human eye. The laser beam is only about 3/4 of an inch in diameter as it travels from the laser resonator, which creates the beam, through the machine's beam path. It may be bounced in different directions by a number of mirrors, or "beam benders", before it is finally focused onto the plate. The focused laser beam goes through the bore of a nozzle right before it hits the plate. Also flowing through that nozzle bore is a compressed gas, such as Oxygen or Nitrogen. Generally speaking, higher laser power is used for cutting, lower laser power is used for engraving. The laser power is adjustable during operation. Turn it down for engraving and turn it up for cutting. The level of laser power will also affect the depth of engraving and the thickness of cutting.

From the technical and economic point of view, CO2 laser machine is not suitable to cut thicker sheet metals compared with fiber laser machine. The typical products that have been used are: automatic elevator structural parts, elevator panel, machine tool and grain machinery enclosures, various electrical cabinets, switch cabinets, textile machinery parts, engineering machinery structural parts, large motor silicon steel sheets, etc.

Patterns, signs, marks and fonts of stainless steel (generally 3 mm thick) or non-metallic materials (generally 20 mm thick) for decoration, advertising and service industries, such as the design of art photo albums, the marks of companies, units, hotels, shopping malls, Chinese and English fonts in stations, docks, and public places.

Special parts that require even slitting. The most widely used typical part is the die-cutting board used in the packaging and printing industry. It requires a slot with a width of 0.7 to 0.8 mm on a 20 mm thick wooden template, and then inserts a blade in the slot. Use fashion on the die-cutting machine to cut out various packaging boxes with printed graphics. A new field of application in recent years is the oil screen pipe. In order to block the sediment from entering the oil pump, a uniform slit with a width of 0.3 mm is cut on the alloy steel pipe with a wall thickness of 6 to 9 mm, and the diameter of the small hole at the starting and cutting hole cannot be greater than 0.3mm.

What is CO2 Laser?

CO2 laser is a pulsed wave laser in which carbon dioxide gas obtains continuous wave or high output area in the infrared of the medium. The wavelength is 10.6μm. It is a light source used for rapid prototyping. High-power lasers are used for cutting and drilling. The medium power output is used for engraving. Since the output wavelength is easily absorbed by water, it is also widely used in medical treatment.

What is CO2 Laser Tube?

The structure of CO2 laser tube is mainly composed of hard glass, resonant cavity and electrode. Let us introduce a three-part detailed structure and principle.

1. The hard glass part:

This part is composed of GG17 material fired into discharge tube, water cooling jacket, air storage jacket and air return pipe. The sealed-off laser generator is usually a three-layer casing structure. The innermost is the discharge tube, the middle is the water purifier, the outermost layer is the gas storage sleeve, and the return gas pipe is used to connect the discharge tube and the gas storage tube.

2. The cavity part:

This part consists of a total mirror and an output mirror. The total mirror of the resonant cavity is generally based on optical glass, the surface is gold-coated, and the reflectivity of the gold-film mirror is above 98% near 10.6um; the output mirror of the resonant cavity is generally made of infrared materials that can transmit 10.6um radiation Germanium (Ge) is the substrate, and a multilayer dielectric film is formed on it.

3. The electrode part:

The laser generators generally use cold cathodes, which are cylindrical in shape. The choice of cathode material has a great impact on the life of the laser generator. The basic requirements for cathode materials are: low sputtering rate and low gas absorption rate. As far as the CNC laser machine is concerned, the quality and performance of the laser tube directly affect the working efficiency of the CO2 laser engraving cutting machine, which is also one of the most important parts of the CNC laser machine.

What is CO2 Laser Generator?

The CO2 laser generator is a gas laser generator with CO2 gas as the working material. The discharge tube is usually made of glass or quartz material, filled with CO2 gas and other auxiliary gases (mainly helium and nitrogen, and usually a small amount of hydrogen or xenon). The electrode is generally a hollow nickel cylinder and a resonant cavity. One end is a gold-plated total reflection mirror, and the other end is a partial reflection mirror polished with germanium or gallium arsenide. When a high voltage (usually DC or low-frequency AC) is applied to the electrode, a glow discharge is generated in the discharge tube, and there is a laser output at one end of the germanium mirror, and its wavelength is in the mid-infrared band near 10.6 microns.

CO2 laser generators are usually made of hard glass, and generally adopt a layered sleeve structure. The innermost layer is the discharge tube, the second layer is the water-cooled casing, and the outermost layer is the gas storage tube. The diameter of the discharge tube of the carbon dioxide laser generator is larger than that of the He-Ne laser tube. Generally speaking, the thickness of the discharge tube has no effect on the output power, mainly considering the diffraction effect caused by the size of the light spot, which should be determined according to the tube length. The longer tube is thicker, and the shorter tube is thinner. The length of the discharge tube is proportional to the output power. Within a certain length range, the output power per meter of discharge tube length increases with the total length. The purpose of adding a water cooling jacket is to cool the working gas and stabilize the output power. The discharge tube is connected to the gas storage tube at both ends, that is, one end of the gas storage tube has a small hole communicating with the discharge tube, and the other end communicates with the discharge tube through the spiral return tube, so that the gas can circulate in the discharge tube and the gas storage tube flow, the gas in the discharge tube is exchanged at any time.
