CO2 Laser Cutting Machines

CO2 laser cutting machine is also named CO2 laser engraving cutting machine or CO2 CNC laser cutting machine. And this cutting equipment using CO2 laser technology, and this kind of CO2 laser machine is usually used to create metal cutting The main gas filled in the laser tube of the CNC laser cutting machine is CO2. Therefore, this laser tube becomes a CO2 laser tube. And the CNC laser cutting machine using this kind of tube is the laser cutting machine. The laser processing machine is mainly used to cut the sheet into the required shape. It is the device that uses the thermal energy of a laser beam to realize CO2 laser metal cutting. The CO2 laser cutter mainly contains three parts: the co2 laser controller, the moving part and the laser emitting part. The control part consists of control software, the central control system, and drivers. The moving part includes guide rails, motors, and belts. The laser emitting part is composed of the laser power supply and the laser tube. The laser generates and releases the laser beam to irradiate on the surface of the work-piece. And the laser beam will melt and evaporate the work-piece to achieve the purpose of cutting and engraving. The CO2 cutting machine has high precision, fast cutting, and is not limited to cutting patterns. The work-piece after the processing of the CO2 cutting machine has smooth incisions without mechanical deformation. The machine can also save materials, and realize low processing costs. The CO2 cutting machine will gradually improve or replace the traditional cutting process equipment. The CNC CO2 laser cutter is also known as acrylic cutting machine, because it can deal with the laser cut acrylic. The laser cut acrylic can be used in various industries, such as laser cut acrylic jewelry, laser cut acrylic mirror, or laser cut acrylic sign. The laser cut acrylic products which made by acrylic cutting machine have a smooth, elegant, and high-finished edge. With the easy operation and high-end cutting results, the CO2 laser cutter as acrylic cutting machine has become more and more popular.

It can cut stainless steel with thickness less than 10mm, and aluminum alloy within 8mm. Applicable industries: This co2 laser cutting machine can make many co2 laser projects. And these co2 laser projects including Shoe materials, leather garments, trademark processing, embroidery, advertising decoration, wood processing, packaging and printing industries, and craft and gift industry, electronic and electrical industry, and model industry (building model, aviation and navigation model, and wood toys), etc.

· Working principle:

Before you learn the laser cutting process, you should have some bases of CO2 cutter working principle. Briefly speaking, when the CO2 laser cutting machine is working, the laser power supply drives the laser tube to emit laser. And then, a laser beam is formed through the focusing lens in the CO2 laser cutting head. The optical mechanism transmits the laser beam and makes it focus on the work-piece on the working table. The work-piece absorbs the high-energy laser heat, and the temperature of the work-piece rises sharply. After reaching the melting point, the material begins to melt and vaporize. At the same time, the high-pressure gas coaxial with the beam directly blows off the molten materials. And the laser cuts through the work-piece and form a very small hole. With the movement of the laser head, numerous small holes appear and connect together to be the outline of cutting. In this way, the CO2 cutter realizes the processing of cutting. As laser cutting has very a high working frequency, the connection of small holes is very smooth. And the products through laser cutting have a high degree of finish.

Working features:

Comparing with other thermal cutting methods, the laser cutting has the general characteristics of fast cutting speed and high quality.  

1. High cutting efficiency

The CO2 laser cutting machine is generally equipped with CNC worktables. And it can achieve fully numerical control for the whole cutting process. During the operation process, the users only need to change the numerical control program based on the processing demand. And then, the machine can complete the cutting of different shapes of parts. The CNC CO2 laser cutting machine can perform both two-dimensional and three-dimensional cutting.

2. Saving materials

Using computer programming, the machine can cut the products of different shapes in the entire piece of material. This maximizes the utilization of materials.

3. Fast cutting speed

The CO2 laser cutting machine has a rapid working speed. And it does not need to clamp and fix the materials on the working table in the cutting process. It not only saves tooling fixtures but also saves auxiliary time for loading and unloading.

4. Good cutting quality

1) Because of the high energy density and fast cutting speed, the cutting can obtain better cutting quality. 2) The cutting incision is very narrow, and the dimensional accuracy of the parts through the laser cutting can reach ±0.03mm; 3) The laser cutting head will not touch the surface of the material. This ensures that it does not scratch the work-piece. 4) After the cutting process of the CO2 cutting machine, the width of the heat-affected zone of the material is very small. And the laser cutting will not affect the properties of the material near the incision, and there is almost no deformation of the work-piece. Furthermore, the cutting accuracy is high, and the geometric shape is also very good.

5. Environmental protection

The cutting process has low noise, low vibration, and no pollution.

6. Non-contact cutting

As the CO2 laser cutter is non-contact cutting, there is basically no thermal deformation of the work-piece. Generally, secondary processing is not required after the cutting of the laser machine.

Except knowing this kind of laser cutting process, you should notice other factors when you using the cutter. In order to guarantee the safety of the operators and the CO2 cutting machine, the users must learn the operation specification. And they shall know the machine and the using skills well.

Key considerations of buying CO2 laser cutting machine

· Materials and processing requirements:

At first, the users need to determine the category and thickness of the materials for laser cutting. As mentioned above, the CO2 laser cutting machine can process most of the non-metallic materials and some relatively thin metal plates. They may make the market survey or find out what machine that the manufacturers in the same industry are using. Of course, consulting with the suppliers as many as possible and getting their suggestions are also feasible.

· Machine size

The machine size of the CNC laser cutting machine determines the amount of work that the users use it to complete. And the size of the machine cannot be changed after the purchase. Therefore, it needs to confirm the amount of cutting work that you plan to complete before making a decision. For example, if you are going to process the large-size boards, you should obviously buy a cutting machine with a large working table. And  the CO2 small laser cutting machine is more flexible and convenient than the large one. People prefer the small laser cutting machine at home or small business.

· Optical quality

The performance and working quality of the CO2 laser cutting machine largely depend on the quality of the optical components. Many people believe that power consumption is an important factor in determining the efficiency of a machine. But the most important is not the power, but the optical quality. The one that determines the optical quality is the laser. Therefore, it needs to choose a machine with good optical quality and operation stability.

· User-friendliness

The users need also to consider the operating system of the CO2 laser cutting machine. The suppliers will make certain system optimization to better adapt to their machines. The users can ask the suppliers to provide the video of machine operation. Or they can visit the factories to actually operate the system for testing. In fact, most of the CO2 laser cutting machines on the market are relatively simple to operate.

· Accessories configuration

Good machine parts determine the accuracy and stability of the cutting machine. For example, the users can figure out what the machine frame is made of, the thickness, and the welding method. These determine whether the machine can remain unchanged for a long time. And they can also ask the suppliers about the brands and quality of the motor, the guide rail, and the cooling system.
