Abstract

Un aparato (10) para grabar por láser y un método para grabar una pieza de trabajo (15), el cual incluye una máscara (11), que tiene al menos una abertura (14) para la formacion de imágenes, la cual se extiende a través de la misma. Un alojamiento (21) de succion se acopla operativamente a una fuente de vacío parcial (19) e incluye una porcion de boca (22), colocada proxima a la máscara (11), para retener la pieza de trabajo (15) y la máscara (11) en contacto a tope. Un conjunto cortador (24) de rayos láser, genera un rayo láser (26), el cual se dirige sobre la superficie expuesta (16) bajo la máscara (11), causando el grabado de la superficie. Los subproductos de vaporizacion o a grabado se retiran de la superficie (16) de vaporizacion a través de un vacío parcial, usado para retener la máscara (11) y la superficie de trabajo (15) juntas. El vacío parcial también se puede usar para enfriar la máscara (11).
