Treatment of slate by means of a laser

摘要

Pieces or plates of slate can be cut, drilled, marked or treated superficially by means of a method based on laser beam irradiation. The great flexibility of this method enables to implement various types of processes on the same piece of slate without having to change the equipment or tool, but only by modifying the processing parameters. This method improves considerably the working conditions of the operator who has to treat the slate plates such as for example the fabrication of slates for roofs or pavements.
