  laser cutting machineAfter determining which focal length lens to use, the relative position of the focus and the surface of the workpiece is particularly important to ensure the quality of the cut. Due to the power density at the focus, in most cases, the focus position is exactly on the surface of the workpiece or slightly below the surface during cutting. Therefore, it is an important condition to ensure that the relative position of the focus and the workpiece remains unchanged throughout the cutting process. Sometimes the lens will heat up due to poor heat dissipation and the focal length will change, which requires us to adjust the focus position in time.

When the focus is at this position, the slit is small and efficient, and the fiber cutting speed is the laser cutting machine to obtain the cutting result.

In most applications, the focus of the beam should be adjusted directly below the nozzle, and the distance between the nozzle of the fiber laser cutting machine and the surface of the workpiece is generally about 1.5mm.

In the process of cleaning the lens, the method of relatively low risk should be used. The following operation steps are set for this purpose and should be adopted by the user. First, use a balloon to blow off the floating objects on the surface of the original, especially the lenses with tiny particles and flocs on the surface. This step is necessary. But do not use compressed air in the production line, because it will contain oil mist and water droplets, which will deepen the pollution of the lens.

Clean the lens slightly with analytical pure. This level of bingtong is virtually water-free, which reduces the possibility of lens contamination.

When the cotton balls dip inbingtongThe lens must be cleaned and cycled under the light. Once the cotton swab is dirty, it must be replaced. Cleaning should be done once to avoid wavy lines. If the lens has two coated surfaces, such as a lens, each surface needs to be cleaned in this way. The surface needs to be protected on clean lens paper.

The laser cutting machine is different from the traditional cutting equipment, and the later use and maintenance cost is very low. At present, the power of the laser cutting machine for cutting metal materials is generally between 500 W-6000 W, and the cutting thickness is generally less than 100mm, which has the following characteristics.

1. High precision, suitable for cutting accessories;

2. The speed is fast, more than 100 times that of wire cutting;

3. The heat affected zone is small and not easy to deform;

4. The cutting seam is smooth without post-processing.
