Why can't the quality of fiber laser cutting machine just look at the high power

In the past few years, many domestic laser cutting machines have been constantly pursuing breakthroughs in the development of power levels, and there has been a phenomenon of competition. It seems that whoever has the largest power level is the most powerful, and the technology and product quality level is the highest. In fact, this idea is one-sided.

Nowadays, with the application of laser cutting machines becoming more and more widespread, the needs of users determine the development and production of products, because users are not only valued at this time which company has made higher-power laser cutting Machine, but value the actual effect produced by your laser cutting machine. In other words, if a customer can cut high-quality workpieces with a 500W fiber laser cutting machine, but the effect of using 1000W is not as good as it is, then the 1000W fiber laser cutting machine is meaningless to the customer .

Methods to improve the cutting quality of fiber laser cutting machine

In the application of laser technology, the application of laser cutting technology accounts for more than 60% of the application share, mainly non-metal cutting, such as textile leather cutting bed, and metal cutting, mainly processing metal materials.

After purchasing fiber laser cutting equipment, users always want to improve the cutting quality, but they often consider cost savings during the cutting process, and some even achieve the ultimate savings, such as auxiliary gas Impurity and so on, and cause the problem of power attenuation. Sometimes when considering profit, the cutting thickness and output power of fiber laser cutting machine are ignored. This article explains some methods to improve the cutting quality of fiber laser cutting machine, hoping to attract the attention of users.

1. The thickness of the metal material

The output power of fiber laser cutting machine is generally 500W and 1000W, the high power is above 2000W fiber laser cutting machine, the fiber laser cutting machine below 1000W power is suitable for cutting carbon steel with thickness below 14mm and stainless steel products below 6mm , The cutting quality of these two types of products under the corresponding material thickness is very good, the cutting speed is fast, and the working efficiency and cost saving conditions of laser cutting can be guaranteed. When these two materials exceed the applicable cutting thickness, the cutting speed will slow down, the cutting quality will deteriorate, and thicker materials will not be able to be cut. In comparison, if the thickness is less than the applicable cutting thickness, such as 1mm stainless steel, the cutting quality will be very good, and it can be applied to downstream links without subsequent processing.

2. Cutting speed

No matter whether the laser cutting speed is too fast or too slow, it is impossible to obtain high-quality cutting quality. Therefore, we should not only consider improving work efficiency and speeding up the cutting speed, or thinking that slow cutting can get good cutting quality. Choosing a moderate cutting speed can obtain excellent cutting quality. This requires strictly following the manufacturer's requirements during the cutting process and controlling the laser cutting process.

3. Laser output power

The higher the output power of the 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 be clear about the thickness and type of the material in the early purchase process to avoid Unable to cut or not get the desired cutting quality. In addition, the higher the degree of agreement between the laser cutting pattern and the material, the better the cutting quality.

4. Material surface roughness

We all know that the flexible processing method of fiber laser cutting is good, and it is not limited by the shape of the workpiece, but it is limited by the surface roughness and cannot achieve the perfect cutting effect. The smoother the surface of the material, the better the cutting quality. 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 an old-fashioned question. Only when the focus position is accurate can the cutting be achieved and the best quality products can be cut.
