CNC laser cutting is a high-precision material cutting process that uses a focused, high-power laser beam to mark, cut or engrave materials to form customized shapes. It has a wide range of applications and is increasingly used in modern industry. application. In some fields, such as aerospace, shipbuilding, automobile manufacturing, and mold manufacturing, CNC laser cutting has also become an indispensable technical means.
Processing:
1. Material preparation: Prepare materials to be processed, usually including metals (such as steel, aluminum, copper), plastics (such as ABS, PMMA, PEEK, PP, Nylon), glass and composite materials, etc.
2. Laser cutting head setting: Fix the workpiece on the workbench, and adjust the position and parameters of the laser cutting head to determine the cutting path and depth.
3. Laser cutting: By controlling the focus and energy density of the laser beam, the laser beam is focused on the surface of the workpiece, causing it to locally heat and melt or vaporize, thereby achieving material cutting.
4. Cooling and cleaning: During the cutting process, you may need to use coolant to reduce the temperature of the workpiece, and regularly clean the cutting area of waste materials and residues.
5. Collect and process waste materials: Collect waste materials generated during the cutting process, process and recycle them.
Advantages:
1. High precision: The laser spot of laser cutting is small, its energy density is high, and the cutting speed is fast. It can achieve cutting of complex shapes and small sizes, maximizing the utilization of materials.
(1) Laser cutting incisions are generally narrow, with both sides of the incisions parallel and perpendicular to the surface, and the dimensional accuracy of the cut parts can reach ±0.05mm.
(2) The cutting surface is smooth and beautiful, and the surface roughness can be guaranteed to be within tens of microns. In many cases, laser cutting can be used as the last process, and the parts after laser cutting can be used directly.
(3) The width of the heat-affected zone of the material after laser cutting is very small, and the performance of the material near the cutting seam is almost unaffected. Moreover, the deformation of the workpiece is small, the cutting accuracy is high, the geometry of the slit is good, and the cross-sectional shape of the slit is a relatively regular rectangle.
2. High efficiency: Compared with traditional cutting methods, laser cutting can realize automated processing of different materials and shapes by adjusting the parameters and control system of the laser cutting machine and only changing the CNC program. It can realize two-dimensional cutting or three-dimensional cutting at a faster speed. Faster and more productive.
3. Fast speed: If laser cutting is performed on carbon steel plates, assuming the steel plate is 2mm thick and the laser cutting power is 1200W, the cutting speed can reach 15000px/min. Materials do not need to be clamped and fixed during laser cutting, which not only saves tooling fixtures, but also saves auxiliary time for loading and unloading materials.
4. High safety: CNC laser cutting is a non-contact processing that can reduce material deformation and damage while protecting your employees from accidental injuries.
Application:
1. Metal processing industry: used for cutting steel, aluminum alloy, copper and other metal materials, such as metal plates, pipes, metal structures, etc., commonly used in automobile manufacturing, aerospace, metal structure manufacturing and other industries. Laser cutting machines can be used for cutting, engraving and drilling metal materials. Through laser cutting processing, precise shapes and sizes can be obtained to meet the requirements of high precision, high efficiency and exquisite appearance in industrial applications.
2. Plastic processing: Laser cutting technology is used to cut various plastic materials, such as polypropylene, polycarbonate, polyvinyl chloride, etc., which are commonly used in electronic products, plastic products and other industries. In the process of producing high-precision products, electronic products, communication products and touch screens, laser cutting technology for cutting plastic materials can greatly improve the accuracy, appearance, quality and efficiency of the products. Laser cutting technology can also effectively avoid deformation, melting or adhesion on the surface of plastic materials or workpieces, while ensuring an efficient, stable and reliable processing process, thereby better adapting to market demand.
In general, CNC laser cutting has high precision, fast processing and a wide range of application fields, providing huge impetus for the progress of the modern processing industry. Through continuous technological innovation and promotion, laser cutting technology will better leverage its advantages in the fields of industrial production, manufacturing and processing, providing more assistance for the development and upgrading of the industry. It is an important cutting and processing technology in modern manufacturing industry.
