Laser cutting machines are now widely used in the fields of automobiles, machinery, electricity, hardware and other electrical appliances. They are loved by many manufacturers because of their fast speed, narrow slit, small heat-affected zone, good verticality of slit margin and lubrication of cutting edge. So how much do you know about fiber laser cutting machines, which are also widely used in laser cutting machines? Today, let the editor give you a popular science of its processing principle and technical characteristics when it works.
Processing principle of fiber laser cutting machine
When the fiber laser cutting machine is working, the laser beam will focus into a very small spot (its minimum diameter can be less than 0.1mm), so that the spot reaches a very high power density, the material under the spot is quickly heated to the vaporization temperature, evaporated to form holes, and move relative to the material at the speed of light, so that the holes are continuous and a very narrow slit is formed, thereby meeting the processing requirements.Technical characteristics of fiber laser cutting machine
1. Good cutting quality. Due to the small laser spot and high energy density, a laser cutting can obtain good cutting quality. The slit of laser cutting is generally 0.1-0.2mm, the width of the heat-affected zone is very small, the geometry of the slit is good, and the cross section of the slit is a relatively regular rectangle. The cutting surface of laser cutting is burr-free, and the surface roughness R can generally reach more than 12.5um. Laser cutting is even used as the last processing step. The cutting surface generally does not need to be processed again and can be directly welded, and the parts can be used directly.
2. Fast cutting speed. Because the heat-affected zone of the workpiece is small and the deformation is very small during laser cutting, it does not need to be clamped and fixed, which can save both clamping fixtures and auxiliary time such as clamping.
3. There are many types of materials that can be cut. Compared with cutting methods such as plasma cutting, laser cutting can cut more types of materials, including metals, non-metals, metal-based and non-metal-based composite materials. For different materials, due to the different thermal physical properties of the materials themselves and the different absorption rates of lasers, they show different laser cutting adaptability.
4. Suitable for the processing of large products. The mold manufacturing cost of large products is very high. Laser processing does not require any molds, and laser processing completely avoids the collapse of the edge formed during material punching and shearing, which can greatly reduce the production cost of the enterprise and improve the grade of the product.
5. Clean, safe and pollution-free. The laser cutting process has low noise, small vibration and no pollution, which greatly improves the working environment of the operator.
6. Not susceptible to electromagnetic interference. Unlike electron beam processing, laser processing is not sensitive to electromagnetic field interference and does not require a vacuum environment.
Of course, there are many advantages of laser cutting machines. If you have not used a laser cutting machine, you might as well try to understand it. As a very important processing method in the sheet metal processing industry, laser cutting is also favored by many manufacturers because of its increasing advantages.Our Alibaba store:https://dadilaser.en.alibaba.com
