If the power of the laser cutting machine is not properly adjusted, it will have a certain impact on the use efficiency of the cutting machine equipment. To make the operation of the equipment more stable, you must select equipment with more appropriate power when purchasing products. In addition to power, there are many other factors that need to be considered. Factors to be considered when choosing.
2. Software system. The software system is provided by the manufacturer, and the powerful company will have a professional technical department to develop and upgrade the software, so that the software can be more compatible with the hardware and its functions can be improved.
3. Consumable accessories. Among all the accessories, laser is very important, and the core of a laser cutting machine is also in the laser.
4. Machine metal laser cutting machine use. Generally, the laser power of the machine used to cut and process metal materials should be at least 500W. If thick metal materials are cut, the laser should be selected to kilowatt level. Especially for continuous lasers, the cutting effect is very good. If it is used to process nonmetals, a 50 watt pulsed laser is enough.
5. Optical instruments. In terms of optical equipment, we need to consider wavelength, semi mirror, full mirror, refractor, etc., so that we can choose a more professional laser cutting head.
Laser cutting of laser cutting machine is one of the methods of thermal cutting. Laser cutting uses high power focusing to irradiate the parts. After some chemical reactions, the material melts to achieve the cutting effect. Laser metal laser cutting machine can be divided into vaporization, melting, oxidation and other cutting categories, and different cutting methods can be selected according to different materials.
1. Laser vaporization cutting
Laser vaporization cutting is to use high-energy and high-density laser beam to heat the workpiece to raise the temperature, and vaporize the material into steam in a very short time. When the steam is ejected, a cut will be formed on the material, thus achieving the cutting effect. However, the heat of vaporization of general materials is very high, so high power laser beam should be used when heating materials. The materials used in laser vaporization cutting generally include extremely thin metal materials and non-metallic materials.
2. Laser melting and cutting
Laser melting and cutting is to heat the material to a certain temperature and melt it, then inject non oxidizing gas through the nozzle coaxial with the beam, and use the pressure of the gas to discharge the liquid metal to form a cut. The energy required for laser melting and cutting is only 1/10 of that for vaporization cutting, and it is not necessary to completely vaporize the metal. Generally, materials suitable for laser melting and cutting include stainless steel, titanium, aluminum and their alloys, which are all materials or active metals that are not easy to be oxidized.
3. Laser oxygen cutting
Laser oxygen cutting uses laser as preheating heat source and active gas such as oxygen as auxiliary gas for cutting. After the gas is ejected, the gas and metal will react with each other to release a large amount of oxidation heat. At the same time, the molten oxide and melt are blown out of the reaction zone to form a notch in the metal. Generally, the materials suitable for laser oxygen cutting are carbon steel, titanium steel, heat treatment steel and other easily oxidized metal materials. Metal laser cutting machine
