A laser cutting machine, as a kind of equipment, utilizes high-power density laser beams to cut, engrave, and punch. Its working principle is that the laser beams generated by the generator irradiate the surface of workpieces to melt, evaporate, and burn the material's surface layer. At the same time, after the high-pressure gas blows away the molten material, the cutting is finished. Laser-cutting technology has been widely applied in metal processing, electronic fabrication, the automotive industry, aerospace and advertising, possessing advantages of high speed, accuracy, narrow slits and small heat-affected zones. Using a laser-cutting machine correctly can improve processing efficiency and product quality, prolong the product lifespan, and lower maintenance costs. On the contrary, improper operation may damage machines, decrease processing quality and even lead to safety incidents. Thus, it’s vital for the operators and business managers to have a deep understanding of laser cutting machines’ working principles, operation procedures, safety precautions and maintenance. The article aims to provide a thorough and detailed user guide on laser-cutting machines. Based on the guide, readers will acquire the basic knowledge, operation procedures and advanced tips and tricks. No matter you are a beginner or a sofisticated operator, the article can provide you with valuable information to improve the efficiency and safety of laser cutting machine utilization. To learn and understand a laser cutting machine, we should answer three questions: What’s a laser cutting machine, and how does it work? How many types of laser cutting machines are there according to lasers? What’s the application of laser cutting machines in various industries? (1)Definition The laser cutting machine is a piece of equipment that utilizes high-power density laser beams to cut, engrave, and punch. Its working principle is that the laser beams generated by the generator irradiate the surface of workpieces so as to melt, evaporate, and burn the material's surface layer. At the same time, after the high-pressure gas blows away the molten material, the cutting is finished. (2)Basic components A laser cutting machine is mainly composed by the following parts: According to laser types, the laser types of laser cutting machines can be divided into CO2 laser cutting machines, fiber laser cutting machines, and YAG laser cutting machines. (1)CO2 laser cutting machines It utilizes CO2 gases as a laser medium, suiting for non-metal material cutting and some metal material cutting. (2)Fiber laser cutting machines Utilizing fiber as a laser medium, it boasts high efficiency, energy savings and low maintenance costs, suitable for various metal materials. (3)YAG laser cutting machine It utilizes neodymium-doped yttrium aluminium garnet crystal as a laser medium, suitable for high-precise and exquisite processing. (4)Comparison This table provides a comprehensive comparison of the three types of laser cutting machines, highlighting their key features, advantages, and disadvantages. Further, I’d like to share you a simpler table to have an even more intuitive comparison. Generally, laser cutting machines are widely applied in many sectors. (1) Metal processing They can cut stain steel, stainless steel and aluminum alloy and are suitable for mechanical manufacturing and sheet metal processing. (2) Electronic fabrication They can cut circuit boards and electronic components, so they are suitable for electronic product production and assembly. (3) Automotive industry They are capable of cutting vehicle components and body parts to improve production efficiency and product quality. (4) Aerospace They are used for cutting aerospace materials and meet high speed and strength processing requirements. (5) Advertising They can cut acrylic, wood and plastic for the production of billboards and signs. Let's view a short video! (1)Types of materials suitable for laser cutting Laser cutting machines can cut all kinds of materials, including metal and non-metal materials. Commonly, here are some materials suitable for laser cutting: (2)Material preparation tips (1)Proper placement and securing (2)Adjusting the laser head (1)Power and speed settings (2)Focus and alignment (1)Importance of test cuts (2)Analyzing test results and adjustments (1)Monitoring the cutting process (2)Post-cut inspection and adjustments Based on the step-by-step operation guides above, operators and beginners can use laser cutting machines correctly and safely and guarantee cutting performance and efficiency. Speed and precision are two key factors during the cutting process. To maximize cutting results, a balance between speed and precision should be achieved during cutting. (1)Balancing speed and precision Laser power directly affects cutting speed and quality. High power improves cutting speed, but decreases cutting edge smoothness. On the contrary, low power improves cutting precision but decreases cutting speed. Therefore, proper laser power adjustment according to material thickness and type is vital. The focal length determines the location of laser beam’s focal point. Appropriate focal length can ensure that laser beams form a small spot on the material surface so as to improve cutting precision. Normally, shorter focal lengths suit thinner materials while longer ones for thicker. The proper cutting paths can reduce the movement distance of a cutting head, improving cutting efficiency. CAD software-designed cutting paths should avoid unnecessary turns and repeatitive cutting. Assist gases, such as oxygen, nitrogen or air, can help clean the molten during cutting, improving cutting quality. Different materials entail different assist gases. For example, oxygen suits carbon steel cutting while nitrogen suits stainless steel and aluminum cutting. (2)Cutting Techniques for Different Materials Different materials present different features, which needs to adopt different cutting techniques This table provides a detailed reference for the choice of assist gas, the function of the assist gas, laser power, cutting speed, and other considerations for cutting different metal materials with a laser. This table provides a quick reference for the choice of assist gas, laser power, cutting speed, and key considerations when laser cutting various non-metal materials. This table provides a quick reference for the choice of assist gas, laser power, cutting speed, and key considerations when laser cutting various non-metal materials.
