Drilling device for drilling fragile plates

摘要

A drilling device for drilling fragile plates, in particular made of glass, comprising at least one drill as well as a support and/or a hold-down, is to be designed in such a way that bending stresses in the drilling area are avoided. This is achieved in that the drill or drills (12) pass through the support (13) and/or the hold-down (14), and the support (13) and/or the hold-down (14) is arranged to oscillate about the longitudinal axis of the drill or drills (12). This construction results in the support and/or the hold-down bearing over the full surface of the plate to be drilled in keeping with the composition of the same, which prevents bending stresses from arising inside the plate (11) to be drilled. <IMAGE>
