SAN Fiber Laser Cutting Machine

Focus debugging is a crucial step in the operation of laser cutting machine. A suitable focus can ensure the accuracy and efficiency of laser cutting. The following tips can help you complete focus debugging quickly and accurately:

Step 1: Distance positioning

The distance should be measured, the focus should be close, and the aiming should be accurate for the first processing

Step 2: Fuzzy rule

Focus should be adjusted far away, the weld should be wide, the material should fly, and the focus should be close to the cutting seam should be narrow

Step 3: Focus debugging

Focus distance plus or minus 0.1 coordinate origin fine adjustment

Step 4: Monitoring adjustment

Cutting starting point, inaccurate position, weak light, please give priority

Step 5: Quality inspection

Focus position, laser is bright, material is focused, and the cutting shape is good

Conclusion

Following the above tips, you can easily master the skills and key points of laser cutting machine focus debugging. Remember, focus debugging is an indispensable and important step in the laser cutting process. Only by correctly debugging a high-quality focus can the cutting quality and efficiency be ensured to reach the best state.

Now laser marking machine has been widely used in all walks of life. It has almost become an indispensable process in the product production line.

Beam quality

Includes output quality and mode stability. Some marking machines have divergent output beams. The marking effect is poor. Or it is unstable when marking for a long time. The product production efficiency is reduced.

Practicality

When choosing a laser marking machine. Be sure to have a targeted understanding of its functions. Whether it is suitable for its own product processing and stability. Because the output power is different. Therefore, the effect of different products is different. Proofing must be done before purchasing laser equipment.

Maintenance

There are good fault diagnosis measures. Generally speaking, when a fault occurs. Users can troubleshoot the fault by themselves.

Operational aspects

Simple and clear operation interface, easy to use. And it is not easy to damage the laser due to operating errors.

Continuous working ability

Applicable to all industries. Different working environments. Pressure resistance. Able to run continuously without affecting corrosion resistance.

Generally speaking, the thicker the material, the more difficult it is to cut. This means that thicker materials require a higher-power laser cutting machine. And there are two common laser cutting machines. One is the CO2 laser cutting machine, and the other is the fiber laser cutting machine. For cutting non-metallic materials, CO2 laser cutting machines are usually the ideal choice. For metal materials, fiber laser cutting machines work better.

Many people will consider the ratio of investment to output. It is normal that the higher the power of the laser cutting machine, the more expensive it is. And the different configurations inside the laser cutting machine will also lead to price differences.

CO2 Laser Cutting Machine

There are many factors that affect the cutting quality of laser cutting machine, such as cutting speed, gas pressure, cooling water temperature, whether the lens is clean, etc., which will affect the cutting speed and cutting quality. SAN LASER will focus on the influence of the focal length and focal position of the focusing lens on the cutting quality.

Generally speaking, short-focus lenses should be selected for high-speed cutting of stainless steel below 3mm, and short-focus or long-focus lenses can be selected for 3-8mm stainless steel. It is recommended to use a long-focus lens for cutting stainless steel or carbon steel above 8mm. The short-focus lens has a small focusing spot size (the laser beam focusing spot size is proportional to the length of the lens), high power density at the focus, and fast cutting speed (the cutting speed of the material is proportional to the laser power density). It is very beneficial for material cutting, but its disadvantages are also obvious. First, the adjustment margin is small. For cutting thicker plates, the width of the cut after cutting on the top and the bottom will be different, thus affecting the cutting quality. At the same time, due to the concentrated cutting power density and finer cutting seams, slag will splash onto the lens surface when cutting the plate, affecting the service life of the lens, so short-focus lenses are generally used for high-speed thin plate cutting.

The power density of the focused spot of the telephoto lens is low, but its focal depth is large. As long as the total power of the laser is large enough, the advantage of cutting thick plates will be highlighted.
