Impregnating Or Coating An Abrasive Tool Patents (Class 51/295)
  • Patent number: 10773361
    Abstract: Methods of making an abrasive article. Abrasive particles are loaded to a distribution tool including a plurality of walls defining a plurality of slots. Each slot is open to a lower side of the tool. The loaded particles are distributed from the distribution tool to a major face of a backing web below the lower side and moving relative to the tool. At least a majority of the particles distributed from the tool undergo an orientation sequence in which each particle first enters one of the slots. The particle then passes partially through the slot such that a first portion is beyond the lower side and in contact with the major face, and a second portion within the slot. The sequence then includes the particle remaining in simultaneous contact with one of the walls and the major face for a dwell period while the web moves relative to the tool.

  • Patent number: 10759023
    Abstract: Provided are abrasive articles that include a plurality of layers, in the following order: a backing; an abrasive layer; and a supersize coat. The supersize coat contains a metal salt of a long-chain fatty acid and clay particles dispersed therein. Advantageously, the clay particles enhance the optical clarity of the supersize coat, allowing printed abrasive articles to be made with thicker supersize coatings. The addition of clay was also found to improve cut performance of the abrasive article relative to articles in which the clay particles are absent.

  • Patent number: 9759015
    Abstract: A superabrasive compact (e.g., a polycrystalline diamond compact) including a substrate and at least one feature for reducing the susceptibility of the substrate to liquid metal embrittlement during brazing operations is disclosed. The superabrasive compact may include a region between the substrate and a superabrasive table in which residual tensile stresses are located. The at least one feature may reduce the susceptibility of the substrate to liquid metal embrittlement by altering the stress state and/or substantially preventing the substrate from being wetted at the residual stress region.

  • Patent number: 9630297
    Abstract: Provided are abrasive articles in which the make layer, abrasive particle layer, and size layer are coated onto a backing according to a coating pattern characterized by a plurality of discrete islands. The coating pattern has features in which all three components are generally in registration with each other, while providing a pervasive uncoated area extending across the backing. Advantageously, this configuration provides a coated abrasive that displays superior curl-resistance compared with previously disclosed abrasive articles. Moreover, this configuration resists loading, resists de-lamination, has enhanced flexibility, and decreases the quantity of raw materials required to achieve the same level of performance as conventional abrasive articles.
