Blades and methods of manufacturing the same. A blade includes a blade body comprising a cutting edge disposed around a perimeter of the blade body. The blade includes a cutter pocket configured to receive a cutter, wherein the cutter pocket is attached to the blade body. The blade includes a cutter attached to the cutter pocket.

This process for manufacturing a closed loop of cutting wire comprises manufacturing a cutting wire comprising a central core extending continuously between two free ends. The central core having a tensile strength higher than 1400 MPa. The process includes welding the two free ends together to form the closed loop of cutting wire, in which: the manufacture of the cutting wire comprises making the central core from a material that is solid-state weldable. The welding is a solid-state welding operation comprising crushing, at a temperature below the melting point of the material of the central core, one of the free ends against the other of its free ends until the two ends have interpenetrated and formed a single uniform body of material.

A saw blade is provided having a noise and stress-reduction structure, the saw blade having a structure in which a plurality of diamond segments are mounted at a first unit and the first unit has a second unit, thereby reducing the noise generated during a cutting operation, while increasing heating performance with a relatively simple configuration, and simultaneously dispersing impact stress so as to prevent the occurrence of cracks.

The invention relates to a sawing tool (7) for forming a surface structure on a road surface, at least having: a shaft (6) and a plurality of diamond saw blades (1), wherein each diamond saw blade (1) has a disc-shaped core with a hole for placing on the shaft (6), and a segment (3) which is arranged on an outer circumference of the core, wherein the diamond saw blades (1) are arranged on the shaft (6) by way of the disc-shaped core. The invention provides for the segments (3) of adjacent diamond saw blades (1) to be in surface contact on a longitudinal side (13), wherein each segment (3) is formed from at least two layers (8.i; i=1 . . . 6) that adjoin one another in the axial direction and each extend in the radial and axial direction, wherein layers (8.i; i=1 . . . 6) of the segment that axially adjoin one another each have different wear resistances (VF, VF.sub.1, VF.sub.2) and the wear resistance (VF, VF.sub.1, VF.sub.2) of the layers (8.i; i=1 . . . 6) in the axial direction alternates over the entire segment (3), wherein a furrow is able to be formed in each case by two layers (8.i; i=1 . . . 6) that axially adjoin one another, in order to set a grip and a level of noise of the road surface, and layers (8.i; i=1 . . . 6) that axially adjoin one another of adjacent segments (3) have different wear resistances (VF, VF.sub.1, VF.sub.2) in order to form an alternating layer structure over the entire sawing tool (7).

Stone fabrication machine and movement system for granite and quartz. The industry has always faced three challenges. 1) Moving a material that is extremely heavy; possibly weighing up to 1200 lbs. 2) not damaging material when moving, processing and installing. 3) Safety. It is the Cut and Polish Complete Fabrication System that installed, with utilities, water, electric, and air are also installed, you can fabricate from start to finish. You provide a forklift and utilities and our fabrication system will do the rest. This is new way to fabricate in two ways using only one person: only moving the piece twice-once to lay on the tables and second loading for delivery. Currently pieces are moved 3 to 6 times averaging 4, meaning taking 2 to 3 fabricators. Utilities distributed throughout machine for cutting and a separate utility bar for operator. This machine becomes the hub of entire shop.

A staggered-teeth diamond saw blade includes a circular steel base and a side wall provided at an outer edge of the steel base. Multiple first diamond cutter heads and multiple second diamond cutter heads are alternately arranged at the side wall through laser brazing; multiple diamond teeth protection cutter heads are uniformly distributed on an external surface of the steel base through high frequency induction brazing; a pre-plating layer is preformed at a welding surface where the side wall is welded with the first diamond cutter heads and the second diamond cutter heads; a pre-plating layer is preformed at a welding surface where the external surface of the steel base is welded with the diamond teeth protection cutter heads. The diamond cutter heads of the present invention are staggered to thicken the thickness thereof while cutting concrete pavement and other materials at high speed.

A diamond cutting tool (200; 200) for enabling a fast cutting start may include a rotatable main body (210) and a cutting portion (220). The rotatable main body may include a substantially circular periphery. The cutting portion may include an interlocking support assembly (280) and a plurality of notched cutters (270). The notched cutters may be disposed around the circular periphery extending outwardly from the main body. The notched cutters (270) may be formed of a first diamond-metal matrix. The interlocking support assembly (280) may be provided radially outwardly of the notched cutters and may include a softer diamond-metal matrix and/or a different diamond concentration therein than the first diamond-metal matrix. The interlocking support assembly may include a reinforcement portion (284) disposed between the notched cutters (270) and a top section (282) covering radially distal portions of the notched cutters.

A cutting tool (1) for producing a narrow trench (2) in the ground (3) for laying cables (4) or the like, comprising a carrier device (5) which has a hub region (6) for connecting the cutting tool (1) to a rotary drive (7) and a peripheral region (8), wherein arranged in the peripheral region (8) of the carrier device (5) are cutting segments (9) spaced from each other in the axial direction (10), wherein the carrier device (5) is in one piece and has a peripheral surface (11) at which are arranged raised portions (12, 13) which project from the peripheral surface (11) in the radial direction (14) and on which the cutting segments (9) are arranged.

A unique design is provided that may increase the strength and performance and extend the life of a saw blade, particularly when used to cut asphalt. The saw blade may include a main body forming teeth, opposing outer plates secured to each tooth and a cutter secured to each tooth between the respective outer plates. Each tooth can form a recessed section in which a base of cutter main body may be positioned. The outer plates may extend over the recessed section. The outer plates may also extend over a notch formed in a rear face of a rear portion of each tooth. Legs of the outer plates may extend radially inward overtop the main body of the saw blade. A front portion of each tooth and the respective outer plates may extend frontward beyond the respective cutter.

A grinding tool, such as a cutting disc, includes a matrix, in particular a sintered metal matrix, and diamonds embedded in the matrix. At least the majority of the diamonds are each assigned at least one wear-promoting particle. The at least one wear-promoting particle is likewise embedded in the matrix.
