Laser cutting the right choice

by:J&D WATER     2020-03-27
A simple method to determine the focus position in industrial production has three: ( 1) Printing method: make the cutting head from the top down movement, laser print on the plastic sheet, print the minimum diameter to focus. ( 2) Inclined plate method: use and a vertical axis Angle of inclined put plastic board makes its level, find the minimum place to focus laser beam. ( 3) Blue spark method: remove the nozzle, blowing air, will play on stainless steel plate, the pulse laser makes the cutting head from the top down movement, maximize until blue sparks as the focus. Laser cutting is one of the advantages of high energy density beam, so the focal spot diameter will be as small as possible, in order to produce tiny cut seam. Because of the focusing lens focal depth is smaller, the smaller the diameter of the focal spot. For high quality, high precision cutting, the effective depth of focus is also related with the lens diameter and cut materials, therefore control focus and cut material on the surface of the position is very important. The following three aspects to analyze cutting focus because of the difference of the material and the request to different choice. 1, cutting the focus on the surface this way also become 0 focal length, usually found in SPC, SPH, SS41 artifacts such as the use of cutting, the focus of the cutter selected when use in close to the surface, this mode of workpiece surface smoothness, up and down in general relatively close to the focus of the cut surface is very smooth, and focus away from the cutting surface is rough. This mode should be according to the practical application of the technical requirements of the upper surface and under surface. 2, cutting the focus in this way also become is the focal length artifacts. When you need to cut the artifacts often used for stainless steel or aluminum plate cutting points inside the workpiece model. But one disadvantage of this approach is that the focus principle of cutting surface, cut relatively bigger than cutting point on the workpiece surface, at the same time, this mode requires cutting air flow, temperature to the foot, cutting punch time slightly long point. So when you choose the material of workpiece mainly for stainless steel or aluminum lamp high hardness material selection. 3, cutting focus on workpiece this way, we also become negative focal length, because the cutting point is not located in the surface of the cutting material is not located in the cutting material, but the location is at the top of the cutting material. This way, the main use and cutting thickness of the material of high. This way the focus position is at the top of the cutting material, mainly because of thick plate need to cut into the picture, otherwise the nozzle conveying oxygen, so it's easy to lead to lack of cutting temperature decline. But one disadvantage of this approach is that the cutting surface is rough, not very practical in high precision cutting. Laser cutting machine processing different artifacts need corresponding with different focus mode, because of the different types of cutting head focus position and adjust in a different way, the user can according to the positive and negative focus different effect when cutting stainless steel, carbon steel, combined with its own processing requirements, to select the focus of the appropriate cutting way, can more show the performance advantages of the laser cutting machine!
