Product Details
Laser cutting is currently recognized as one of the most efficient, high-quality and high-precision metal processing methods. There are many factors that affect laser cutting, and the nozzle is one of them. Choosing the right nozzle when cutting various materials can make processing easier. How to choose the right nozzle correctly? Let's take a look today.
The nozzle, also known as the copper nozzle, is one of the most important components in laser cutting. The nozzle is located at the lower end of the cutting head. Both the laser beam and the auxiliary gas act on the cut material through the nozzle. Its main function is to collect auxiliary gas and form high pressure, release it into the surface and slit of the cutting material, and blow it away during the cutting process. The resulting molten and vaporized base metal leaves a clean cut; while preventing contaminants such as slag, soot, etc. from bouncing upwards, the inner lens is protected.
When the nozzle center is not coaxial with the laser center, the cutting quality will be affected as follows. First, it affects the cut part. When the cutting gas is ejected, the gas volume is not uniform, and it is easy to cause a melting point on one side of the cutting section and no phenomenon on the other side. It has little effect on cutting thin plates below 3mm. When cutting plates over 3mm, the impact is more severe and sometimes it cannot be cut. The second is to affect the quality of sharp corners. When cutting sharp or small-angle workpieces, local over-melting is prone to occur, and when cutting thick plates, it may not be possible to cut. The third is to affect perforation. The perforation is unstable and the time is not easy to control. The penetration of thick plates will cause over-melting, the penetration conditions are not easy to grasp, and the impact on the perforation of thin plates is small.
The nozzle of the laser cutting machine can assist the rapid ejection of gas, which can effectively prevent debris such as molten stains from rebounding upward, thereby protecting the focusing mirror. At the same time, it can control the area and size of gas diffusion, which will affect the cutting of the laser cutting machine. quality.
