A manual ceramic cutter with an adjustable set-square, having a set-square (1) installed at one of the longitudinal extremities of a base (2) for supporting the ceramic items to be cut, and a manually-operated cutting head (3) installed with the possibility of displacement along a number of longitudinal guides (4). This cutter comprises adjustment means (13, 14) of the perpendicularity of the set-square (1) with regard to a cutting line (L1) of the cutter, and fixing means (11, 12) of the set-square (1) to the base (2). It further comprises visual verification means of the perpendicularity of the set-square (1) with regard to the cutting line (L1).

A machine for working glass slabs includes a supporting structure, a slab grinding section having grinding heads, a conveyor assembly adapted to move the glass slab, and a slab drilling section having a conveyor adjacent to the conveyor assembly. The slab grinding section has suckers for keeping the glass slab next to a working plane spaced and/or offset with respect to the advancement plane, and a computerized numeric control assembly to perform workings on the glass slab.

A sintered magnet sawing apparatus is provided comprising a cylindrical work carrier mounted on a horizontal rotating spindle and having a regular polygonal shape in a perpendicular cross section, and a plurality endless elastic belts adapted to force a work of sintered magnet against the carrier surface to secure the work thereto and adapted to travel synchronously with and counter to the rotation of the carrier in a circulatory manner. In accordance with rotation of the carrier, the work is delivered to the peripheral surface of the carrier, secured thereto by the elastic belts, moved further forward and cutoff machined by an outer cutoff blade. The divided work is moved further forward, released and discharged from the carrier.

A cutting guide comprising: a substantially planar plate with a lip arranged to extend orthogonally from the plate along at least one edge of the plate. Two or more slots are provided to guide a cutting blade. An entrance to at least one of the slots on an outer face of the lip tapers to guide the cutting blade into the slot and wherein a portion of an inner face of the lip that corresponds to the slot is shaped to define a corner in which material to be cut is positioned.

A cutting apparatus for cutting corner pieces formed of stone or other materials for use as building faces or for cutting flat pieces is disclosed herein. The cutting apparatus includes a frame with a first and a second conveyor operatively attached to the frame. The first and the second conveyors are configured to carry a workpiece from a first end of the frame to the second end of the frame. The first conveyor is disposed at an angle of about 45 degrees to a ground surface supporting the cutting apparatus. The second conveyor is disposed at an angle of about 45 degrees to the ground surface supporting the cutting apparatus, wherein the second conveyor is positioned perpendicularly to the first conveyor so as to form a V-shaped channel therewith. The cutting apparatus further includes a first cutting blade operatively attached to the frame and positioned generally parallel to the first conveyor and a second cutting blade operatively attached to the frame and positioned generally parallel to the second conveyor.
