CNC laser machine is a kind of equipment that uses a laser beam to cut or engrave various materials. It has the advantages of fast processing speed, high precision, good quality, and low cost. It is widely used in metal, non-metal, composite materials, and other fields. However, not all materials are suitable for processing with CNC laser machines. Some materials may cause unsatisfactory processing results due to their physical, chemical, or mechanical properties, and may even damage equipment or endanger personnel. This article will explain which materials cannot be cut with a CNC laser machine, as well as the reasons and effects.
Materials that cannot be cut with CNC laser machines mainly include the following categories:
1. Highly reflective materials.
Such materials include non-ferrous metals such as copper, aluminum, gold, and silver, as well as surface-treated materials such as gold plating, silver plating, and aluminum plating. This type of material has a high reflectivity for laser, which will greatly reduce the energy of the laser beam, thus affecting the depth and quality of the cut. At the same time, the reflected laser beam can also cause damage to the optical components of the equipment and even cause a fire. Therefore, this type of material is generally not suitable for CNC laser cutting unless a special laser or cutting process is used.
2. Flammable and explosive materials.
Such materials include organic materials such as wood, paper, cloth, plastic, and rubber, as well as materials containing flammable and explosive components, such as gases, liquids, powders, etc. During the laser cutting process, this type of material will generate a large amount of heat and smoke, which can easily cause combustion or explosion, causing safety hazards. Therefore, this type of material is generally not suitable for cutting with CNC laser machines unless measures such as low-power lasers or increased ventilation and smoke exhaust are used.
3. Materials containing toxic and harmful ingredients.
Such materials include plastic materials such as polyvinyl chloride, polycarbonate, and fiberglass, as well as materials containing toxic and harmful components such as heavy metals, radioactivity, and biology. This type of material will release toxic and harmful gases or dust during the laser cutting process, causing harm to the human body and the environment. Therefore, this type of material is generally not suitable for cutting with CNC laser machines unless professional protective equipment or handling methods are used.
To sum up, although the CNC laser machine is an efficient processing equipment, it also has some limitations and cannot cut all materials. When selecting materials, you should consider their characteristics such as laser reflectivity, flammability, and toxicity, as well as their impact on processing effects, equipment safety, human health, environmental protection, etc., and avoid using unsuitable materials or taking other measures. Corresponding measures are taken to ensure the normal operation and high-quality processing of CNC laser machines.
