Fiber laser cutting machine how to choose the best speed to cut high quality materials The power of the laser affects the speed at which the laser machine cuts the sheet, and the cutting speed of the laser machine affects the quality of the sheet cut. Under certain conditions of laser power, there is an optimal range of cutting speeds, too fast or too slow will have an impact on the surface flatness of the cut material. Excessive cutting speed 1. The laser beam and the material are in contact with each other for a short time, which may result in uncutting and sparks. 2. Some areas can be cut, but others cannot. 3. Causes delamination of the entire cut section. 4. The result is that the plate cannot be cut off in time, the cut section shows a diagonal striped path and the lower part produces melt stains, as shown in the figure below. Cutting speed is too slow 1. The time taken for the material and the laser to interact with each other increases, resulting in over-melting of the cut sheet and a rougher cut section. 2. The cutting slit will widen accordingly, causing overburning in smaller rounded or sharp corners and not getting the desired cutting effect. 3. Low cutting efficiency, affecting production capacity. Cutting speed judgment method 1. reasonable cutting speed: cutting sparks are spread from top to bottom, the cutting surface presents a smooth, lower no slag. 2. cutting speed is too fast: cutting sparks are tilted. 3、Cutting speed is too slow: cutting sparks show no diffusion and less, cohesion together.
