Laser cutting machine occupies a large area in industrial manufacturing. Many metal materials, whether stainless steel, carbon steel or alloy materials, can be cut without deformation.
The optimum cutting speed range of the metal cutting machine can be selected according to the equipment description or determined by testing. Because the thickness, material, melting point, thermal conductivity and surface tension after melting are different, the cutting speed will change accordingly.
In fact, the cutting speed of laser cutting machine is very important. The best cutting speed range can be selected according to the equipment description or determined by testing. Due to the thickness of the material, different materials, melting point, thermal conductivity and surface tension after melting, the cutting speed will also change accordingly.
Main cutting advantages of metal cutting machine:
1. The cutting quality can be improved by appropriately increasing the cutting speed. The cut is slightly narrower, the cut surface is smoother, and the deformation can be reduced at the same time.
2. The cutting speed is too fast, causing the cutting energy to be lower than the required value. The jet in the cutting seam can not immediately blow away the molten cutting melt and form a large amount of resistance. As the slag hangs on the notch, the surface quality of the notch decreases.
3. When the cutting speed is too slow, the laser beam will irradiate the material surface for a long time, thus making the incision wider. The molten materials on both sides of the notch gather and solidify at the bottom edge, forming a slag suspension that is not easy to clean. Moreover, due to excessive heating and melting, the upper edge of the notch forms a fillet.
In order to meet the increasing requirements of industrial production on quality and production efficiency, we must pay attention to solving various key technologies and implementing quality standards, so that this new technology can be more widely used in China.
Laser cutting material has no burr, smooth surface and high precision, which is superior to CNC punch and plasma cutting. It is understood that due to the slow cutting speed and poor cutting quality of the optical fiber laser cutting machine, more attention should be paid to the maintenance and routine maintenance of the laser cutting equipment. Only in this way can work efficiency, product quality and economic benefits be guaranteed to the greatest extent.
