Abstract

Equipment for making a hole or cavity formation in a curved or planar wall element, and for cutting out a disc-shaped piece of material fitting the hole or cavity formation, includes a frame with devices for fixing it on the wall element, and a carriage displaceably mounted in a first linear direction. A slide is mounted to be displaceable in a direction perpendicular to the first linear direction and carries a tool unit. The carriage has wheel sets which are biased against the wall element. The wheel sets are pivotable and displaceably mounted on a respective guide slide, which is mounted to be displaceable in the first linear direction.
