Abstract (en)

A device (1) for engraving slabs (L) of relatively fragile material, such as ceramic or glass, adapted for use in combination with a multiaxial machine tool having a working head (2) placed above a substantially horizontal support surface (P), wherein the head (2) comprises a fork (3) movable along three Cartesian axes (X, Y, Z) and rotatable around a vertical axis (Z) and adapted to support a working unit (4). The device (1) comprises a movable member (8) operatively associable to the fork (3) and having at its lower end a rolling tool (9) with a substantially horizontal rotation axis (R<sub>2</sub>), configured to engrave a slab (L) resting on the support surface (P) along a predetermined engraving path. A method for engraving slabs (L) of relatively fragile material, such as ceramic and glass, using the device (1).
