What are the factors that influence the precision of fiber laser cutting machine?

     Fiber laser cutting machine is equipped with different fiber laser sources, such as Raycus and IPG, which will affect the cutting accuracy, in addition, different thickness and different hardness of metal materials can also affect the precision of fiber laser cutting machine.
     What is a fiber laser cutting machine?

Fiber laser cutting machine is a laser cutting machine which USES fiber laser generator as light source.Fiber laser is a new type of fiber laser which produces laser beam with high energy density and concentrates on the surface of the workpiece, so that the area irradiated by the ultra-fine focus spot on the workpiece is melted and gasified instantly. The automatic cutting can be realized by moving the spot irradiated position by the numerical control mechanical system.

     What factors determine the cutting precision of fiber laser cutting machine? Let's look at the specific. 

When we want to cut the metals with more accuracy by a fiber laser cutting machine, we must understand which aspects will affect the accuracy of the cutting, we will briefly introduce you to the following: 

     1. The laser beam emitted is tapered, so the cutting slit is also tapered, in this case, the slit of 1mm stainless steel will be much smaller than the 4mm thickness.Therefore, the shape of the laser beam is a major element to affect the cutting accuracy. Under such a cone-shaped laser beam, the thicker of the workpiece, the lower accurate it will be and the larger of the cutting slit.

     2. When the cone-shaped laser beams focus on together, the laser point is smaller at this time, The laser cutting precision becomes higher and higher, especially the width of the slit becomes smaller. At this time the smallest spot can reach 0.01mm. This is also one of the factors that affect the cutting accuracy of laser cutting machines. 

     3. In this case, the cutting accuracy of different materials is slightly different. Even with the same material, the precision of the cut will vary if the composition of the material is different. Therefore, the workpiece material also has a certain influence on the laser cutting accuracy. 

     4. The accuracy of the workbench, if the workbench is not accurate or other reasons, it will lead to high-precision laser cutting effect. Under the same conditions, high precision cutting of stainless steel than aluminum, copper and brass.
