Users want to improve the cutting quality after purchasing the optical fiber laser cutting equipment, but they often consider the problem of cost saving in the cutting process, and some even achieve savings, such as impure auxiliary gas, which leads to the problem of power attenuation. Sometimes when considering the profit, the problems of the cutting thickness and output power of the fiber laser cutting machine are ignored. This article explains some methods to improve the cutting quality of the fiber laser cutting machine, hoping to attract the attention of the majority of users.

1. Thickness of metal material

The output power of the fiber laser cutting machine is generally 500W and 1000W, and the high power of the fiber laser cutting machine is more than 2000W. The fiber laser cutting machine with the power of less than 1000W is suitable for cutting carbon steel products with the thickness of less than 14mm and stainless steel products with the thickness of less than 6mm. The cutting quality of these two types of products under the corresponding material thickness is very good, and the cutting speed is fast, which can ensure the working efficiency and cost saving conditions of the laser cutting. When these two materials exceed the applicable cutting thickness, their cutting speed will slow down and the cutting quality will deteriorate, and thicker materials will not be cut. In contrast, if the thickness 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 error of improving work efficiency and speeding up the cutting speed, or think that slow cutting can obtain good cutting quality. Select a moderate cutting speed to obtain excellent cutting quality. This requires strict operation in accordance with the requirements of the manufacturer during the cutting process, and control the laser cutting process.

3. Laser output power

The higher the output power of the optical fiber laser cutting machine, the higher the thickness of the material that can be cut, and the better the quality of the corresponding cutting. Therefore, the user must specify the thickness and type of his own material in the early purchase process to avoid the inability to cut or the inability to get 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 fiber laser cutting has good flexible processing means, which is not limited by the shape of the workpiece, but cannot achieve good cutting effect due to the limitation of surface roughness. The more flat the material surface is, the better the cutting quality will be. Therefore, the stability of the machine tool is also very important. It is necessary to ensure the working environment of laser cutting.

5. Focus of laser cutting

This is a commonplace problem. Only when the focus position is accurate can we achieve cutting and produce high-quality products.
