Description

TECHNICAL FIELD

[0002] The stainless steel honeycomb plate is a product composed of a special adhesive, in which the surface plate is made of a drawn stainless steel plate or a mirror stainless steel plate, the back plate is made of a galvanized steel plate, and the core material is an aluminum honeycomb core. The laser cutting machine is usually used for processing the stainless steel honeycomb core base material. During the cutting process of the stainless steel honeycomb plate, the light beam is focused into a very small focal point through the lens of the cutting head, so that the focal point reaches a high power density. The material is quickly heated to the melting and vaporization temperature. At the same time, a high-speed airflow from the coaxial or non-coaxial side blows out the melted and vaporized material, forming a material cutting hole. With the relative movement of the focal point and the material, the hole forms a continuous and narrow cutting seam, completing the cutting of the material.
