How to Choose Suitable Metal Fiber Laser Cutting Machine Parameters?

Metal fiber laser cutting machine is a device that uses a high-energy-density laser beam to cut metal materials. It has the advantages of fast cutting speed, high cutting quality, wide cutting range, and simple operation. The cutting effect and efficiency of metal fiber laser cutting machines are affected by many factors, the most important of which is the selection of cutting parameters. Cutting parameters include laser power, cutting speed, auxiliary gas, focus position, nozzle distance, etc. Different parameters have different effects and effects on the cutting process and cutting results. This article will introduce how to choose appropriate metal fiber laser cutting machine parameters.

Laser power refers to the laser energy output by the laser, which determines the maximum cutting thickness and cutting efficiency of laser cutting. Generally speaking, the higher the laser power, the greater the cutting thickness and the faster the cutting speed, but it will also increase cutting costs and energy consumption. Therefore, when selecting laser power, it should be weighed based on actual cutting needs and should not be too high or too low. In addition, the selection of laser power must match parameters such as cutting speed, auxiliary gas, and focus position to achieve the best cutting effect.

Cutting speed refers to the moving speed of the laser head along the cutting trajectory, which directly affects the cutting quality and cutting efficiency. Generally speaking, the faster the cutting speed, the shorter the cutting time, and the higher the cutting efficiency, but it will also reduce the cutting quality, leading to wider cutting seams, rough cutting surfaces, and increased heat-affected zones. Therefore, when choosing the cutting speed, it should be weighed according to the actual cutting needs and should not be too fast or too slow. In addition, the selection of cutting speed must match parameters such as laser power, auxiliary gas, and focus position to achieve the best cutting effect.

Auxiliary gas refers to the gas ejected from the nozzle during the cutting process. Its function is to blow away the slag in the cutting seam, cool the cutting area, reduce thermal impact, and improve cutting quality. The type and pressure of auxiliary gas have a great impact on the cutting effect. Generally speaking, the types of auxiliary gases can be divided into inert and reactive gases. Inert gases such as nitrogen, argon, etc. are mainly used to prevent material oxidation and are suitable for cutting highly reflective materials such as stainless steel and aluminum alloys; reactive gases such as oxygen, Air, etc., are mainly used to increase the combustion reaction of materials and improve cutting efficiency. It is suitable for cutting low-reflective materials such as carbon steel. If the pressure of the auxiliary gas is too high or too low, it will affect the cutting quality. If the pressure is too high, it will cause the cutting slit to become wider, the cutting surface will be rough, and the heat-affected zone will increase.

The focus position refers to the position of the laser focus relative to the workpiece surface, which directly affects the cutting quality and cutting efficiency. The selection of the focus position should be adjusted according to the type and thickness of the material. Generally speaking, the positive focus is suitable for cutting materials with large thickness and high hardness, such as carbon steel, stainless steel, etc., to obtain narrower slits and smoother cuts. Negative focus is suitable for cutting materials with small thickness and low hardness, such as aluminum alloy, copper, etc., which can achieve faster cutting speed and smaller heat affected zone; Zero focus is suitable for cutting materials with medium thickness and medium hardness, such as Titanium alloys, nickel alloys, etc. can achieve better-cutting effects and higher cutting efficiency.

The nozzle distance refers to the distance between the nozzle and the workpiece surface, which affects the injection effect of the auxiliary gas. The nozzle distance refers to the distance between the nozzle and the workpiece surface, which affects the injection effect and cutting stability of the auxiliary gas. Generally speaking, the smaller the distance between the nozzles, the greater the injection force of the auxiliary gas and the higher the cutting quality. However, it also increases the risk of collision between the nozzle and the workpiece, resulting in nozzle damage or cutting interruption. Therefore, when selecting the nozzle distance, it should be weighed according to the cutting needs and should not be too small or too large.
