How to understand the relationship between cutting quality and speed of metal laser cutting machine

Currently, metal laser cutting machines play a significant role in the industrial equipment and manufacturing sector. They are capable of cutting various metal plates and pipes with ease. To aid in the cutting process, specific auxiliary gases are used depending on the material being cut. For instance, when cutting carbon steel, oxygen is utilized as the auxiliary gas. This gas triggers an exothermic chemical reaction with the molten metal, oxidizing the material and assisting in removing the slag from the cutting seam. Additionally, the auxiliary gas that enters the nozzle serves to cool the focusing lens, preventing contamination from smoke and dust, which could lead to overheating of the lens.

The cutting speed of metal laser cutting machine is very important. The best cutting speed range can be selected according to the equipment instructions or determined by experiments. The cutting speed varies accordingly due to factors such as the thickness of the material, different materials, melting point, thermal conductivity, and surface tension after melting. Its main performance:

1. Increasing the cutting speed moderately can enhance incision quality by making it narrower, flatter, and reducing deformation.

2. Excessive cutting speed leads to lower cutting energy, causing difficulty in blowing away molten cutting melt and resulting in backdraft and damage to the incision surface.

3. Slow cutting speed prolongs laser exposure, widening the incision and causing molten material to solidify as slag, making it hard to clean. The upper edge of the incision may also melt excessively, forming rounded corners.

Laser cutting offers precise, smooth, and burr-free results, making it superior to CNC punching and plasma cutting. In various mechanical manufacturing sectors, modern laser cutting systems are favored for their ability to cut workpieces of different shapes and sizes with ease. While laser cutting may be slower than die punching, it eliminates the need for molds, mold repairs, and saves time on mold replacement, ultimately reducing processing and production costs. Overall, laser cutting is a more cost-effective option.
