Does the speed of metal laser cutting machine affect the quality?

Speed and quality are often inversely proportional, the pursuit of speed quality will be reduced, the pursuit of quality will affect speed. So, does the speed of a metal laser cutter affect quality?

It is important for Metal Laser Cutting Machine to choose the right cutting speed when cutting. The suitable cutting speed range can be selected according to the equipment description or determined by test. Due to the different thickness of materials, different materials, melting point, thermal conductivity and surface tension after melting and other factors, the cutting speed also changes accordingly.

The incision quality is affected by the appropriate increase of cutting speed, that is, the incision is slightly narrower, the incision surface is more flat, and the deformation can be reduced.
The cutting speed is too fast, so that the cutting line energy is lower than the required value, and the jet in the cutting joint cannot quickly blow off the melted cutting melt immediately, resulting in a large trailing amount. With the hanging slag of the incision, the surface quality of the incision decreases.

When the cutting speed of the metal laser cutting machine is too low, because the cutting place is the anode of the plasma arc, in order to maintain the stability of the arc itself, the anode point or anode region should find the conduction current near the slit near the arc, and at the same time, more heat will be transferred to the radial direction of the jet.

It will make the incision wider, the molten material on both sides of the incision gathered and solidified at the bottom edge, forming a hanging slag that is not easy to clean up, and the upper edge of the incision formed a rounded corner due to excessive heating and melting.

When the speed of the metal laser cutter is low, the arc can even be extinguished because the incision is too wide.

Metal laser cutting machine cutting quality and speed is inseparable, need to be used carefully in the actual operation.
