Abstract: A dual angle guide (3) for ceramic cutting machines (1) includes a base (16); first and second positioning elements (4, 5) disposed on the base; a sector (9) calibrated with fixed angles for each positioning element; a first fixed stop (11) and a second fixed stop (12) for locating the positioning elements at a chosen angle on the respective calibrated sector (9); and rotation elements (13) for rotating the positioning elements in such a way that the positioning elements make it possible to make cuts in the ceramic piece (10) at different angles. The cuts are made by a cutting tool mounted to a sliding carriage (6). Each of the first and second positioning elements is rotatable in both a clockwise direction and an anti-clockwise direction in order to facilitate the scoring and cutting of the ceramic piece at various angles.

Abstract: An adapter device for ceramic cutting machines (2) that includes an adapter plug (1) for the hole (8) of the tool holder (7) of a ceramic cutting machine (2. The plug (1) includes a hollow cylindrical shape with a stop (12) that performs an axial fixation in a direction of the plug (1) in the hole (8) of a tool holder (7) of the ceramic cutting machine (2); and a longitudinal slot (13) that leaves open the inner hollow space of the plug (1) along its entire length. The longitudinal slot (13) has a narrower segment in a part of the plug (1) that is nearest the end (21) having the stop (12), and a wider segment in the part of the plug (1) that is near the end (22) of the plug (1) opposite the stop (12).

Abstract: The object of the invention is a modular machine for cutting ceramic pieces, comprising two towers (7), a central profile (5) and two lateral profiles (4) fastened to the two towers (7), at least two rigidity providing elements (14) between each lateral profile (4) and the central profile (5), two guides (9) fastened to the towers (7) and a number of guide reinforcements (28) around the guides (9), providing the guide (9) and a tool-bearing assembly (3) with precision, at least two floating platforms (6) supported on the rigidity providing elements (14) which constitute a support for the ceramic piece, a tool-bearing assembly (3) that may be displaced along the guides (9), such that the lateral profiles (4), the central profile (5), the guides (9) and the guide reinforcements (28) are fastened to the towers (7) in a dismountable fashion.

Abstract: Blade (1) for a cutting tool (2) of a ceramic cutting machine (3) comprising a disc-shaped geometry with a specific cutting diameter (H); with at least one conical surface (13) at each side of the cutting perimeter (12), the conical surfaces (13) closest to the symmetry axis (11) being truncated by two truncation planes perpendicular to the symmetry axis (11) of the blade (1), such that if the conical surfaces (13) closest to the symmetry axis (11) of the blade (1) are imaginarily extended towards its vertex, both define two tangency conical surfaces (15) with an imaginary sphere (16) the center of which is located on the symmetry axis (11) of the blade (1), where the ratio between the cutting diameter (H) of the blade (1) and the diameter (D) of said imaginary sphere (16) is equal to a number with a value comprised between 1.5 and 1.7.

Abstract: The object of the present invention relates to a breakage system applied to ceramic cutting machines, which configuration and design allows it to be used by right-handed or left-handed people. This breakage system solves the unresolved problem in the present state of the art with respect to the use of the cutting machine, such that it facilitates the cutting process regardless if the operator is right-handed or left-handed. This invention is especially applicable to the construction industry.

Abstract: An adjustment device for manual cutting tools is provided. The cutting tool for which the device is intended takes the form of pruning shears having two arms with the respective cutting blades thereof hinged to one another by a transverse bolt forming the main element of the device. A tightened nut for locking the bolt is provided with a transverse hole into which a lateral locking screw is screwed, thereby enabling the hinge to be adjusted. The nut and the locking screw are positioned in a recess in the cutting blade such that the nut cannot rotate when the bolt is being manipulated using a protrusion of the nut housed in a cavity in the cutting blade. The through-hole provided in the cutting blade for the bolt includes a bushing which enables the bolt to be better adjusted in the hole.
