In the professional fiber laser cutting machine, for the parts with high cutting precision or large thickness, several key technologies must be mastered and solved. Focus position control is one of them. One of the advantages of laser cutting is the high energy density of the beam, so the diameter of the focal spot should be as small as possible in order to produce a narrow slit. Because the smaller the focal depth of the focus lens, the smaller the focal spot diameter. For high-quality cutting, the effective focal depth is also related to the lens diameter and the material being cut. Therefore, it is important to control the position of the focus relative to the surface of the material being cut.
Such a kind of equipment has its own selection criteria in the whole selection process. In fact, once we want to select this kind of equipment, we must determine the production range, and make effective selection according to the processing materials or cutting thickness. Only in this way can we determine the number of purchased equipment or relevant machine models, and pave the way for subsequent procurement, How to choose a professional fiber laser cutting machine will have more selection criteria in this regard.
1. Fine cutting
When shopping, you must also check their cutting fineness. Basically, they can be controlled between 0.1mm and 0.2mm.
2. Look at the deformation of the material
If the laser cutting machine is used for cutting, the material deformation effect of good equipment is very small.
3. Smoothness of cutting surface
In the process of actual cutting, the smoothness of the cutting surface is also very important. It is necessary to see whether there are some burrs on the cutting surface. Generally, there will be some burrs. Basically, it is determined by the thickness of cutting or the gas used. There is no burr below 3mm. The effect of nitrogen is good, followed by oxygen. If there is air inside, Then this effect is also poor. The burr of professional fiber laser cutting machine is relatively few, and it can even be said that the surface cut without burr is very smooth.
4. Look at the power
Most manufacturers have their own power requirements for laser cutting machines and other equipment. From the existing situation, most of the factories also cut metal plates below 6mm, so there is no need to buy high-power cutting machines.
