Factors affecting the cutting quality of metal sheet laser cutting machine

XT Metal Plate Laser Cutting Machine

We all know that metal sheet laser cutting machines are mainly mechanical equipment for rapid cutting of various metal materials, such as stainless steel, carbon steel, alloy steel, copper, titanium, and other metal materials. However, in actual use, there are many factors that can affect the cutting quality of metal sheet laser cutting machines, such as speed, power, and nozzle. Below, we will understand how these factors affect the cutting quality of metal sheet laser cutting machines

The Influence of Laser Cutting Machine Speed on Metal Sheet Cutting

The impact of the speed of the metal sheet laser cutting machine on different materials is basically consistent. If the speed is too fast, it may cause inability to cut, sparks splattering, and the cross-section showing diagonal lines, resulting in a thicker cutting cross-section and molten stains in the lower part. If the speed is too slow, it will lead to over melting of the cutting plate, rough cutting section, and corresponding widening of the cutting seam, resulting in melting of the entire area in smaller rounded or sharp corners, and not achieving the ideal cutting effect. The speed of feed can be determined from the cutting spark; Generally, cutting sparks diffuse from top to bottom, and if the spark is tilted, the feed speed is too fast; If the sparks appear non diffusive and few, agglomerating together, it indicates that the feed speed is too slow.

The Influence of Laser Cutting Machine Power on Metal Sheet Cutting

The impact of power on cutting is mainly manifested in the quality of the cutting section. When using a metal sheet laser cutting machine for laser cutting, if the power is set too high, it will cause the entire cutting surface to melt and the cutting seam to be too large, making it difficult to achieve good cutting quality; If the power setting is insufficient, it will cause cutting molten stains and scars on the cutting section; Even the power is too small to cut the workpiece. Especially for thick plates with high requirements in terms of cutting surface and whole plate cutting, which require stable cutting efficiency, high-power cutting technology has to be relied on, with 10000 watt level laser cutting technology as a representative.

The influence of nozzle on metal sheet laser cutting machine

Usually, the impact of the nozzle on cutting is mainly reflected in the poor coaxiality of the beam and airflow caused by the nozzle being out of circle, resulting in inconsistent or even impossible cutting sections. The surface of the cutting nozzle is uneven due to collision or melting adhesion, which affects the tunnel and cutting effect. The size of nozzle aperture has a significant impact on cutting quality and perforation quality. The larger the nozzle aperture, the poorer the protective ability of the protective lens. During cutting, the possibility of sparks splashing from molten materials bouncing upwards is high, which shortens the lifespan of the lens.

In addition, the cutting quality is also influenced by factors such as process parameters, material quality, gas purity, and beam quality.

The cutting process of powerful metal sheet laser cutting machines has driven the rapid development of the laser cutting industry. In order to obtain high-quality laser cutting products, it is necessary to fully grasp cutting techniques before operation, reduce the impact of various factors on cutting quality, and improve the quality of cut parts.
