    摘要: An abrasive disk has one or more layers in which abrasive grains are embedded. Embedded in one layer is a sensor for detecting an original periphery of the abrasive disk that has been altered by wear. The sensor has at least one closed conductor loop which is arranged at a radial distance from the original periphery such that, when the original periphery is worn by more than the radial distance, the conductor loop is interrupted. A transponder emits a radio signal indicative of whether the conductor loop is closed or interrupted.

    摘要: The invention concerns a tool for machining of materials, specifically a grinding tool, which has a substantially rotationally symmetrical shape with respect to a rotation axis (R), the tool comprising an outer shell centered about the rotation axis and defining an internal space therein, wherein at least a part of a surface of the outer shell is provided with an abrasive coating or component, wherein the outer shell encases an internal skeleton structure in the internal space, the internal skeleton being integral with the outer shell and defining void volumes in the internal space thereby establishing material and void volumes of the internal space, and wherein the material to void ratio M/V is distributed substantially identically along each radius (r) centered around the rotation axis (R) and its corresponding symmetrical radius (r′). The invention also concerns a method for producing such tool.

    摘要: A machining apparatus machines an end face of a tapered roller with a grinding wheel. The machining apparatus includes a support mechanism configured to support the tapered roller, a wheel unit on which the grinding wheel is mounted, and a base configured to support the wheel unit so that the wheel unit is swivelable about a center line in a vertical direction. A machining point where the grinding wheel is brought into contact with the end face of the tapered roller supported by the support mechanism is located on an extension of the center line serving as a swivel center of the wheel unit.

    摘要: A method of manufacturing a grinding wheel, and a grinding wheel. After a first overcoat layer is formed on each of CBN abrasive grains, a second overcoat layer that is plastically deformed under a pressure lower than a pressure under which the first overcoat layer is deformed, is formed on the outer side of the first overcoat layer to manufacture coated abrasive grains. The coated abrasive grains are subjected to pressure-molding to be formed into a prescribed shape under a pressure that is equal to or higher than a pressure under which the second overcoat layer is plastically deformed. The second overcoat layers are deformed and flow to form a molded material having a structure in which the first overcoat layers contact each other, and the flowing second overcoat layers are moved into clearances between the coated abrasive grains. By sintering this, CBN abrasive grains are dispersed at a prescribed distance that is determined by the degree of outer radius of each first overcoat layer, and vacancies are arranged therebetween at a prescribed density.

    摘要: The abrasive grinding wheel includes an annular abrasive grain layer formed by a diamond abrasive grain or CBN abrasive grain and fixed to an outer peripheral surface of a cylindrical grinding wheel core by an adhesive agent. The abrasive grinding wheel further includes a waterproof agent applied on both side end surfaces and an inner peripheral surface of the cylindrical grinding wheel core in order to prevent any water ingress into the inside of the core.

    摘要: A forming tool for forming leading edges of turbine blades is disclosed. In various embodiments, a forming tool may comprise a cylindrically-shaped body having a notch around the circumference of the cylindrically-shaped body. The notch may be positioned perpendicularly to a center axis of the cylindrically-shaped body. Further, the notch may have a notch contour with an upper notch contour and a lower notch contour, and where the notch contour is a relief of a selected turbine blade leading edge. The forming tool may be a grinding tool or a cutting tool. Moreover, a forming process may comprise forming, by a forming tool, a first portion of a turbine blade leading edge with a rough edge result, and forming, by a milling cutter, a second portion of the turbine blade leading edge with a rough edge result.
