Factors affecting the cutting accuracy of fiber laser cutting machine

Fiber laser cutting machine cutting accuracy is currently the industry's main standard parameter to measure the quality of machine tools. In the sales of equipment, sales staff will have a specific description of the processing performance of the product. Among them, the cutting accuracy of fiber laser cutting machine is mostly 0.5mm error range, of course, there are a few manufacturers to provide high-precision laser cutting machine tool processing accuracy of up to 0.3mm error, but overall the cutting accuracy is still there is a certain error range, which is what we call the processing scale tolerance. So what factors determine the cutting accuracy of fiber laser cutting machine? Let's look at it specifically.

When we want to cut metal more accurately by fiber laser cutting machine, we must understand which aspects will affect the cutting accuracy, here we will briefly introduce:

1. The beam emitted by the laser is tapered, so the cutting slit is also tapered, in this case, the slit of 1 mm stainless steel will be much smaller than the slit of 4 mm thickness. Therefore, the shape of the laser beam is the main factor affecting cutting accuracy. Under this tapered laser beam, the thicker the workpiece, the lower the accuracy and the larger the cutting slit.

2. When the conical laser beam is focused together, the laser spot is smaller at this time, and the laser cutting accuracy is getting higher and higher, especially the width of the cutting slit becomes smaller. At this time, the smallest spot up to 0.01 mm. This is also one of the factors affecting the cutting accuracy of the laser cutting machine.

3. In this case, the cutting accuracy of different materials is slightly different. Even for the same material, if the material composition is different, the cutting accuracy will be different. Therefore, the workpiece material also has a certain impact on the laser cutting accuracy. Under the same conditions, the cutting accuracy of stainless steel is higher than that of aluminum, copper and brass.
