Introduction to Laser Cutting Machines
Tube laser cutting machines are high-speed, precision tools that can be used to precisely cut a wide variety of materials. Laser cutting is a non-contact process, so there is no direct contact between the cutting tool and the material, reducing wear and tear and creating a cleaner, higher-quality cut. The following guide will help you understand how laser cutting machines work and how to use them effectively.
How do Laser Cutting Machines Work?
Laser cutting machines use a focused beam of light to cut through materials. This is done by directing a concentrated beam of light to a specific location on the material and using a computer to accurately control the laser to move it in the desired direction. The laser beam melts, burns, or vaporizes the material, leaving behind a clean-edged cut.
Types of Laser Cutting Machines
Laser cutting machines come in a range of sizes and power levels. Smaller machines are ideal for hobby or home use, while large industrial laser cutters are capable of cutting large pieces of material.
CO2 Laser Cutters
CO2 laser cutters use a laser beam created by a gas mixture of carbon dioxide, nitrogen, and other substances. These machines are capable of cutting a wide range of materials, including metals, plastics, and wood.
Fiber Laser Cutters
Fiber laser cutters use a laser beam generated by a high-powered diode. They can cut through a range of materials at high speeds, and offer a good balance between cost and performance.
YAG Laser Cutters
YAG (yttrium-aluminum-garnet) laser cutters are a type of high-power laser cutter that can be used to cut thick materials like metal. YAG lasers are more expensive than other types of laser cutters, but offer superior cutting speeds and accuracy.
The advantages of laser cutting machines are as follows:
1、High cutting speed: The cutting speed of laser beam is very fast, up to several meters per second;
2、Small heat-affected zone: When the laser beam acts on the workpiece, only a small area near the incision is heated, and the heat-affected zone is very small;
3、Narrow slit: The width of the slit is only about 0.1-0.3mm, which is much smaller than that of other cutting methods;
4、Good cutting quality: The laser cutting machine can get very good cutting quality, and the surface of the workpiece cut by the laser cutting machine is smooth and burr-free;
5、Flexible cutting: The laser cutting machine can cut any complex plane shapes, and can also cut pipes and other three-dimensional shapes;
6、Able to cut a variety of materials: The laser cutting machine can cut not only metal materials, but also non-metal materials such as plastics, rubbers, ceramics, etc.
The disadvantages of laser cutting machines are as follows:
1、High equipment cost: The laser cutting machine is a high-tech product with a very high cost;
2、High power consumption: The power consumption of the laser cutting machine is very high, which is about 10-20 times that of the traditional cutting machine;
3、High requirement for the processing environment: The laser cutting machine has very high requirements for the processing environment, and the processing workshop must be well ventilation, dust-free and clean;
4、Potential safety hazards: The laser beam of the laser cutting machine is harmful to the human body, so the operator must take precautions to avoid being exposed to the laser beam.
The specific process of laser cutting machine is as follows:
1. First of all, according to the drawings, the workpiece to be cut is placed on the worktable of the laser cutting machine;
2. Then, the CNC system of the laser cutting machine is used to input the processing program;
3. After the processing program is inputted, the laser cutting machine starts to work, and the laser beam is emitted from the laser cutting head to cut the workpiece along the processing path inputted in the program;
4. After the cutting is completed, the operator removes the processed workpiece from the worktable of the laser cutting machine.
The key points in the operation of laser cutting machine are as follows:
1. When inputting the processing program, be sure to input the correct processing path and processing parameters, so as to avoid mistakes in the cutting process;
2. During the cutting process, pay attention to the changes of the workpiece and the laser cutting head, and stop the machine in time if there is any abnormal situation;
3. After the cutting is completed, clean the worktable and the laser cutting head in time to avoid affecting the next cutting.
Tips for Using Laser Cutting Machines
- Ensure that you have the right materials to work with. Not all materials can be cut with a laser.
- Use carefully calculated speeds and settings so that you don’t cut too slowly or too quickly.
- Check the design of the part you are cutting to ensure that there is no interference with the laser beam.
- Test different materials for cutting with scrap material before working with your actual product.
- Be careful when working with reflective materials, as they can cause the laser beam to bounce back in unpredictable directions.
Conclusion
Laser cutting machines offer a powerful and precise way of cutting a range of materials. Understanding the types of laser cutters available and the advantages of using laser cutting technology can help you make the most of this powerful tool.

As an important tool in modern industry, laser cutting machines have been widely used in various fields, especially in the sheet metal processing industry. In order to better use laser cutting machines, it is necessary to understand the basic principle, advantages and disadvantages of jq laser cutting machines, as well as the specific process and key points of laser cutting machines.
The basic principle of laser cutting machine is to use the high energy density of laser beam to irradiate the workpiece locally, so that the workpiece material starts to melt and evaporate, and at the same time, the gas around the incision blows away the molten material, so as to make the incision smooth.
