A machine for producing tiles from a block, in particular a block of marble, granite and the like, includes a support surface for supporting the block; a plurality of first cutters for cutting the block parallel to a first horizontal direction, the first cutters being placed above the support surface, including respective lower edges, configured to cut the block on the upper part, the lower edges being placed at the same adjustable height, with reference to a vertical direction, and being arranged aligned along at least a first horizontal axis, parallel to a second horizontal line, orthogonal to the first horizontal direction; a second cutter for cutting the block parallel to the second horizontal line, the second cutter being configured to move along a second horizontal axis relative to the support surface, the second horizontal axis being parallel or inclined with respect to the second horizontal line by a first angle α<90°, the second cutter having, during use, a resting position, wherein it does not interact with the block, and a working position, including a lower edge placed at the same adjustable height as the first cutters; a horizontal blade for cutting the block along a horizontal plane, including a first cutting side placed at the same adjustable height as the first cutters, and the support surface is configured to move on the horizontal line along a first cutting direction, relative to the first cutters, to the second cutter, and to the horizontal blade, the horizontal blade being placed downstream of the first horizontal axis and the second horizontal axis, with reference to the first cutting direction. A method for cutting a block of marble and the like, into a plurality of tiles is also disclosed.

The present invention relates to an automatic sawing machine for cutting blocks of natural and/or concrete stone material, which comprises a single motorized conveyor belt having a conveyor plane for transporting the material to be cut and a driving wall placed substantially at 90° with respect to said conveyor plane so that all together contribute to give the conveyor belt a substantially “L”-shape. The machine comprises a support fixed to the machine and a rotatable crown element placed at the top of said support, provided of a plurality of protuberances spaced apart from each other so as to allow each of said protuberances to be inserted in turn into one of said slot obtained in one of said second portions of said strips, following the movement of the conveyor belt. Methods of cutting blocks of natural and/or concrete stone material with the automatic sawing machine are also provided.

A floor leveling apparatus and method for cutting parallel grooves in a hardened body which is configured to assist in utilizing a grinder to finish surfaces in a planar manner.

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.

In this way, the problem to synchronize the movement of two or more belts moving forward simultaneously is avoided, also reducing maintenance times and costs, and at the same time obtaining a higher feed speed.

Stabilized cutting tool assemblies. A cutting tool assembly for use with a reference surface includes a tool holder having a rotational axis. The tool holder is arranged for attachment to a drive source arranged to rotate the tool holder and move the tool holder relative to a reference surface. The cutting tool assembly includes a rotatable cutting tool coupled to the tool holder. The cutting tool includes a cutting surface and has a first portion and a second portion. The first portion is disposed adjacent the tool holder. The cutting tool assembly includes a stabilizer coupled to the cutting tool adjacent the second portion. The stabilizer has a bearing surface. The bearing surface is positioned on the second portion to abut the reference surface and to stabilize the cutting tool when the drive source moves the tool holder and the cutting tool to a position adjacent the reference surface.
