Durante a grava\u00e7\u00e3o, o laser aquece e distorce a superf\u00edcie microsc\u00f3pica do material. Dessa forma, a superf\u00edcie gravada a laser se expande e ganha textura. Isso pode colorir o material em preto, branco ou cinza, sendo a maneira mais eficaz de marcar permanentemente a maioria dos tipos de materiais. A grava\u00e7\u00e3o a laser \u00e9 adequada para todos os tipos de metais. Como a marca \u00e9 superficial, ela \u00e9 frequentemente usada para gravar materiais finos. Por exemplo, c\u00f3digos de matriz de dados de produ\u00e7\u00e3o, n\u00fameros de s\u00e9rie, c\u00f3digos de barras e logotipos, etc. Outras solu\u00e7\u00f5es de marca\u00e7\u00e3o a laser permanente incluem a marca\u00e7\u00e3o a laser e a grava\u00e7\u00e3o a laser.<\/p>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t\n<\/div>\n<h3>O princ\u00edpio de funcionamento da m\u00e1quina de grava\u00e7\u00e3o a laser para metais<\/h3>\n<p>O princ\u00edpio b\u00e1sico da grava\u00e7\u00e3o a laser consiste em focalizar um feixe de laser de baixa pot\u00eancia e alta qualidade (geralmente laser ultravioleta ou laser de fibra) em um ponto muito pequeno. Dessa forma, forma-se uma alta densidade de pot\u00eancia no ponto focal, fazendo com que o material se vaporize e evapore instantaneamente, formando orif\u00edcios, fendas e ranhuras. A m\u00e1quina de grava\u00e7\u00e3o a laser para tecnologia de metais inclui micro e nanocorte a laser, riscagem, grava\u00e7\u00e3o, perfura\u00e7\u00e3o e assim por diante.<\/p>\n<h3>Caracter\u00edsticas da m\u00e1quina de grava\u00e7\u00e3o em metal<\/h3>\n<p>A m\u00e1quina de grava\u00e7\u00e3o a laser em metal apresenta caracter\u00edsticas como processamento sem contato, alto grau de flexibilidade, alta velocidade de processamento, aus\u00eancia de ru\u00eddo, pequena zona afetada pelo calor e a capacidade de concentrar o feixe em um ponto espec\u00edfico por meio de um comprimento de onda de laser muito pequeno. O uso da tecnologia de grava\u00e7\u00e3o a laser permite obter boa precis\u00e3o dimensional e qualidade de processamento em opera\u00e7\u00f5es de perfura\u00e7\u00e3o, riscagem, grava\u00e7\u00e3o e corte. Em particular, a intera\u00e7\u00e3o com certos materiais (como a poliimida) constitui um \u201ctrabalho a frio\u201d de \u201ca\u00e7\u00e3o fotoqu\u00edmica\u201d, permitindo obter o efeito de n\u00e3o carboniza\u00e7\u00e3o.
