Abstract: A device (1) for processing a slab of stone or stone-like material, comprises a support table (2), adapted for receiving slab, and a fixed guide rail (3) running in a first direction (X) along a side of the support table. The device further comprises an arm (4), extending in a cantilevered manner, in a second direction (Y) from the guide rail and across at least a portion of the support table. The arm is displaceable relative the guide rail in a third direction (Z). A method for processing a slab of stone or stone-like material is also disclosed.
