After purchasing the fiber laser cutting machine, customers all want to improve the cutting quality, but they often consider the problem of cost saving in the cutting process, and some even achieve the extreme saving, such as the impure auxiliary gas, which eventually leads to the problem of power attenuation. Sometimes, when considering the profit, the thickness and output power of the fiber laser cutting machine are ignored. Here are some ways to improve the quality of fiber laser cutting machine. I hope it can help you.
1. Thickness of metal materials
The output power varies. Fiber laser cutting machine with power below 1000W is suitable for cutting carbon steel with thickness below 10mm and stainless steel with thickness below 5mm. These two types of products have very good cutting quality and fast cutting speed under the corresponding material thickness, which can ensure the working efficiency and cost saving conditions of laser cutting. When these two materials exceed the applicable cutting thickness, the cutting speed will slow down, the cutting quality will become worse, and the thicker materials will not be cut. In contrast, if it is less than the applicable cutting thickness, such as 1mm stainless steel, its cutting quality will be very good, and it can be applied to the downstream link without subsequent processing.
2. Cutting speed
No matter whether the laser cutting speed is too fast or too slow, high-quality cutting quality cannot be obtained. Therefore, we can not only consider the misunderstanding of improving work efficiency and speeding up the cutting speed, or think that slow cutting can get good cutting quality. Choosing a moderate cutting speed can obtain excellent cutting quality, which needs to be operated in strict accordance with the manufacturer's requirements in the cutting process and control the laser cutting process.
3. Laser output power
The higher the output power of the fiber laser cutting machine, the wider the applicable range of the thickness of the cutting material, and the better the corresponding cutting quality. Therefore, users must be clear about the thickness and type of their own materials in the early purchase process, so as to avoid being unable to cut or not getting the desired cutting quality. In addition, the higher the coincidence between the laser cutting mode and the material, the better the cutting quality.
4. Material surface roughness
We all know that the flexible processing method of fiber laser cutting machine is good, which is not limited by the shape of the workpiece, but it is limited by the surface roughness and cannot achieve perfect cutting effect. The smoother the material surface is, the better the cutting quality will be. Therefore, the stability of the machine tool is also very important, and it is necessary to ensure the working environment of laser cutting.
5. Focus of laser cutting
This is an old-fashioned problem. Only when the focus position is accurate can cutting be achieved and the best quality products be cut.
