What should we pay attention to when choosing optical fiber cutting machine?

Good cutting quality. The width of the notch is narrow (generally 0.1-0.5mm), the accuracy is high (generally the error of hole center distance is 0.1-0.4mm, the error of contour dimension is 0.1-0.5mm), and the roughness of the notch surface is good (generally RA is 12.5-25) μ m) Generally, the cutting seam can be welded without further processing.

Fast cutting speed. For example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min; The cutting speed of 2mm thick stainless steel is 3.5m/min, with small heat affected zone and minimal deformation.

Clean, safe and pollution-free. The working environment of operators is greatly improved. Of course, in terms of accuracy and notch surface roughness, CO2 laser cutting cannot exceed EDM; In terms of cutting thickness, it is difficult to reach the level of flame and plasma cutting. However, the above significant advantages are enough to prove that CO2 laser cutting has replaced and is replacing some traditional cutting methods, especially the cutting of various non-metallic materials. It is an advanced processing method with rapid development and increasingly wide application.

Non contact cutting. During laser cutting, the cutting torch has no contact with the workpiece and there is no tool wear. To process parts with different shapes, it is not necessary to change the 'tool', but only to change the output parameters of the laser. The laser cutting process has the advantages of low noise, small vibration and no pollution.

There are many kinds of cutting materials. Compared with oxyacetylene cutting and plasma cutting, there are many kinds of laser cutting materials, including metal, non-metal, metal matrix and non-metal matrix composites, leather, wood and fiber. However, different materials show different laser cutting adaptability due to their different thermophysical properties and laser absorptivity.
