What affect processing accuracy of the metal laser cutting machine?

Compared with traditional processing technology, metal laser cutting machine has higher processing accuracy and better cross-sectional effect without secondary processing; this is also the reason why many companies choose metal laser cutting machine, but many companies have found the cutting accuracy of metal laser cutting machine equipment Sometimes it is not ideal, which will affect the subsequent processing flow; then what are the factors that affect the processing accuracy of the metal laser cutting machine?

 1.Processing material

When the metal laser cutting machine processes metal, the cutting accuracy of different materials will be different. Even the same material, if the composition of the material is different, the cutting accuracy will be different. Therefore, the material of the workpiece also has a certain influence on the accuracy of laser cutting. Generally, the smoother the material, the higher the processing accuracy.

Therefore, when processing different metal materials, you can make samples in advance to find out more suitable parameter settings for this type of material.

2.Auxiliary gas and nozzle

During the processing of the metal laser cutting machine, the auxiliary gas and the nozzle play the role of cleaning and controlling the cutting speed; the uneven pressure and temperature in the air flow will cause the change of the air flow field density, which will limit the focus of the beam energy and cause renewal Focus or beam divergence, and affect the accuracy of metal cutting.

3. The accuracy of the workbench

When processing a metal laser cutting machine, the worktable will vibrate with the vibration of the laser head; the high-precision worktable is matched with a stable linear guide and stepper motor, the cutting accuracy will be higher; if the worktable is uneven or other reasons , It will also affect the processing accuracy of the laser cutting machine.

4.The shape of the laser beam

The laser beam emitted by the metal laser cutting machine is conical, so the cutting gap is also conical. The shape of the laser beam is also the main factor that affects the cutting accuracy of the metal laser cutting machine. The smaller the spot after the laser beam is focused, the smaller the slit and the higher the processing accuracy.

Under the condition of this conical laser beam, the greater the thickness of the workpiece, the lower the accuracy, and therefore the larger the gap. Therefore, when processing metals of different thicknesses, choosing the right laser power can achieve better results.
