Abstract

"CORTE A LASER COM LENTE COM DUPLO FOCO DE PEçAS METáLICAS DE ESPESSURA ESTREITA". A invenção se refere a um processo de corte por feixe de laser de uma peça metálica que tem uma espessura inferior a 5 mm, no qual se utiliza uma lente com dupla focalização, permitindo focalizar o feixe de laser em pelo menos um primeiro (PF1) e um segundo (PF2) pontos de focalização distintos um do outro, e situados sobre o eixo do feixe, caracterizado pelo fato de a lente apresentar um comprimento focal (FL) compreendido entre 80 e 135 mm.
