Laser Cutting Machine Cutting Speed And Cutting Effect

Laser cutting has the advantages of burrs and high efficiency. Many equipment manufacturers choose to use laser cutting machines to process suitable sheet metal and parts. The processing efficiency and accuracy are better than traditional punching and molding processes. Laser processing has no mold consumption, which saves processing costs and speeds up the production cycle at the same time, which greatly improves the overall processing efficiency. Due to the different types and thicknesses of processed materials, as well as the influence of many factors, the cutting speed will also change accordingly, which in turn affects the cutting effect.

1. Appropriate cutting speed can improve the cutting quality, that is, the cut is slightly narrower, the surface of the cut is flatter, and the deformation can be reduced at the same time.

2. The cutting speed is too fast so that the cutting line energy is lower than the required value, and the jet in the cutting seam cannot quickly blow off the molten cutting melt immediately and form a large back drag, accompanied by cutting slag and cutting The surface quality is degraded.

3. When the cutting speed is too low, because the cutting site is the anode of the plasma arc, in order to maintain the stability of the arc itself, the anode spot or anode area must find a place to conduct current near the slit closest to the arc, and it will flow to the jet at the same time. More heat is transferred in the radial direction, so that the incision becomes wider. The molten material on both sides of the incision gathers and solidifies at the bottom edge, forming dross that is not easy to clean, and the upper edge of the incision becomes rounded due to excessive heating and melting.

4. When the speed is extremely low, the arc may even go out due to the wide incision. It can be seen that good cutting quality and cutting speed are inseparable.
