When we were in the use of laser cutting materials should pay attention to the several points

In the laser cutting machine for cutting parts with high precision or large thickness, must grasp and solve the several key techniques. The focus position control is one of them. Laser cutting is one of the strengths of the beam energy density is high, so the diameter of the focal spot will be as small as possible, in order to produce a narrow kerf. Because of the focusing lens focal depth is smaller, the smaller focal spot diameter, for high quality cutting, the effective depth of focus and lens diameter also related to cut materials. So control focus is cut relative to the location of the material surface is also very important.



as a result of the laser power density affects the cutting speed is larger, the lens focal length selection is a very important problem. After the focused laser beam spot size and the lens focal length is proportional to the, after short focal length lens to focus the light beam spot size will be small, the focus in high power density, is advantageous for material cutting; But its drawback is that the depth is very short, adjust the margin is small, is generally applicable to the high speed cutting of thin materials. Due to the long telephoto lens has a wide depth of focus, so long as has the enough power density, suitable for cutting thick artifacts.



when laser cutting steel. Oxygen and focused laser beam is through the nozzle is cut into CaiLiaoChu. To form a beam. Of the airflow into the incision are basic requirements of the gas flow, higher speed, so that make incisions enough oxidation material adequately exothermic reaction, and also has enough momentum to molten material injection blow out. The laser cutting nozzle adopt a taper hole with end small round hole structure. When use from nozzle side ventilation with certain pressure. Is made of pure copper, smaller volume, is quick-wear part.
