摘要： The present disclosure relates to an alloy wire rod and a preparation method and application thereof. The alloy wire rod is made of a tungsten alloy, and the tungsten alloy contains tungsten and an oxide of cerium. The alloy wire rod has a wire diameter of equal to or less than 100 μm; and the alloy wire rod has a tensile strength of greater than 3,800 MPa. The wire diameter of the alloy wire rod is equal to or less than 60 μm; the diameter of a push-pull core wire of the alloy wire rod is less than 350 μm; the elastic ultimate strength of the alloy wire rod is greater than 2,500 MPa; and the tensile strength of the alloy wire is greater than 4,200 MPa. In the present disclosure, the alloy wire rod having ultra-high strength and good toughness is obtained by doping an oxide of cerium.

摘要： A wire saw includes a U-shaped cutting area. An endless sawing wire loop runs between a plurality of wire pulleys including at least two displaceable cutting area pulleys, displaceable wire tensioning pulleys and wire plane changing pulleys. The endless wire loop defines a first cutting area plane P1 in the U-shaped cutting area and at least one further wire loop plane dissimilar from the first cutting area plane. The wire plane changing pulleys guide the sawing wire between the first cutting area plane and the further wire loop plane P2. A wire driving pulley is driven by a wire drive motor. A cutting area pulley actuator runs the cutting area pulleys along each side of the workpiece cutting area. The displaceable wire tensioning pulleys are displaceable by at least one tensioning actuator within the further wire loop plane P2 to maintain a tensioned sawing wire.

摘要： A method of using a cutting blade on a portable band saw. The method includes the step of providing a portable band saw. A cutting blade is provided which includes at least one tooth that has a linear rake face with a positive rake face angle transitioning uninterruptedly from a tip of said cutting tooth into a single radius to define a portion of said cutting tooth. The portable band saw is used to cut and object with the cutting blade of the portable band saw in a single continuous linear cut direction.

摘要： A plurality of bushings are coupled to one another via a series of bolts to provide an interlocking, articulating cutter. The bolts have a cylindrical end and a convex end. The convex ends are seated inside a concave socket coupled to the bushings. The cylindrical ends are coupled to a convex nut seated inside another concave socket coupled to an adjacent bushing. The convex ends of the bolts are configured to articulate inside the seat of the concave sockets. A washer may be placed between the bushings to provide a desired amount of flexibility and/or rigidity. The outer surface of the bushing comprises a cutting structure, such as a milled or clad cutting structure.

摘要： Sawing tool forms a surface structure on a road surface, has a shaft and number of diamond saw blades, each diamond saw blade has disc-shaped core with hole for placing on shaft. A segment is on outer circumference of core, and saw blades are arranged on shaft by disc-shaped core. Segments of adjacent diamond saw blades are in surface contact on longitudinal side, each segment formed from two layers adjoining one another in axial direction and extending in radial and axial direction. Axially adjoining layers of segment each have different wear resistances and wear resistance of layers in axial direction alternates over axially entire segment, so a furrow is formed by two layers adjoining one another, in order to set a grip and a noise level of the road surface. Axially adjoining layers of adjacent segments have different wear resistances forming an alternating layer structure over entire sawing tool.

摘要： A hole saw includes a base member configured to secure the hole saw to a drive device and a blade member extending orthogonally from each side of the base member. Each blade member is configured having respective distal ends that flex transversely to a longitudinal cutting direction of the blade member. Responsive to rotational movement of the hole saw via the drive device against a structure, a medial location of each blade member creates an initial respective linear cutting path into the structure, and further movement of the respective blade members into the structure cause the distal ends of the respective blade members to flex transversely to the cutting direction and follow the initial linear cutting path despite the rotational movement of the hole saw relative to the structure to produce a linear cut through the structure.
