How to define the cutting quality of a fiber laser cutting machine

Cutting accuracy is the first factor in determining the quality of a CNC laser cutting machine.The four factors that affect the cutting accuracy of CNC laser cutting machine.

A. Firstly,The laser cohesion size of the laser generator. If after cohesion, the laser beam is very small, the cutting precision will be very high. After cutting, the gap will be very small too. It explains that the cutting quality and cutting precision are very good.If the beam from the laser generator is big, then cutting gap is also big. In this condition, the thicker the workpiece, the bigger the gap.

B. Secondly,The precision of the frame. Before working, we need check the each part of the frame. The vertical and horizontal of the frame should be very good. If there’s 0.1mm deviation of each part, with the machine working, it will be bigger and bigger.

C. Thirdly,The shape of the laser beam. If the beam from the laser generator is taper, then cutting gap is also taper. In this condition, the thicker the workpiece, the bigger the gap.

D. Different material will also cause different cutting quality. For example, in the same condition, there’s a big difference for cutting stainless steel and aluminum. For cutting stainless steel the precision and cutting edge will be better than aluminum.

The general speaking, the define the cutting quality by those 5 standards.

A. The quality of the cutting edge.

B. The size of the slag of the cutting edge.

C. The trimming perpendicularity and inclination.

D. The cutting edge fillet size.E. Flatness.
