摘要： There is provided a method of forming cutting blades using selective laser melting comprising positioning a first part of an elongate strip with pre-formed teeth within a powder bed, forming coating layers layer-by-layer to create a cutting surface on each pre-formed tooth by repeatedly depositing a layer of powder on the powder bed and scanning a laser beam over the deposited powder to fuse powder to the pre-formed teeth.

摘要： A saw blade comprises a blade backer with a pair of side surfaces that extend substantially parallel to each other. An intermediate surface extends between the pair of side surfaces of the blade backer. A plurality of teeth extends from the intermediate surface. The plurality of teeth comprises an asymmetrically ground tooth tip having a first rake face angle and a symmetrically ground tooth tip having a different, second rake face angle.

摘要： 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.

摘要： 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.

摘要： Metal sleeves are used as carriers for the abrasive layer of sawing beads. Such sawing beads are threaded on a steel cord and are separated by a polymer thus forming a sawing cord for sawing of hard and brittle materials such as stone or concrete. These metal sleeves have a large influence on the overall performance as well as on the cost of the sawing cord. The inventors propose the method of metal injection molding to make the metal sleeves in large quantities with an optimized geometry which is not possible with the current methods for making the metal sleeves. Over and above the inventive sleeves are particularly well suited for application of the abrasive layer by means of laser cladding. Beads made by laser cladding on the inventive metal sleeves as well as sawing cords comprising such beads are therefore part of the invention.

摘要： Saw cords made of saw beads threaded on a steel cord, where the saw beads are separated by polymer spacers. The saw beads have a metal sleeve of which the outer surface is covered with an abrasive layer. The inner surface of the sleeve has with two sets of parallel grooves in a first and second axial part of the sleeve. The two sets of parallel grooves differ in at least one of the groove angle, the groove offset or the groove spacing, thereby preventing axial movement of the sleeve and blocking the rotation of the saw bead.
