Patents by Inventor Anne PIQUEREZ

Anne PIQUEREZ has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Cutting insert, cutting tool comprising such an insert and methods for producing and repairing such a tool
    Patent number: 10814435
    Abstract: The invention relates to an insert brazed on a body of cutting tools (101), consisting of: a metal substrate (11), in the form of plates, having a surface for attachment to the tool body; a high-temperature, brazing, alloy layer (12); an intermediate layer; and a ceramic plate (14). The brazing alloy layer connects the metal substrate (11) of the ceramic plate (14) via the metal layer (13). A low-temperature brazing layer (1) connects the insert (1, 1?) to the body of the tool (101).

  • Cutting tool for machining abrasive materials, notably wood-based materials
    Patent number: 10369633
    Abstract: Cutting tool for machining by removal of matter from abrasive materials such as a material based on wood particles; tool characterized in that it is composed of a mounting endowed with at least one machining element, and of which at least the machining edge is composed of a high-homogeneity oxide ceramic platelet composed of Al2O3 and ZrO2, with this platelet being obtained from: a homogeneous Al2O3—XZrO mixture of Al2O3 nano-particles of average size smaller than 1 ?m, and ZrO2 nano-particles of tetragonal structure and average size smaller than that of the Al2O3 particles, with the ZrO2 content X being between 5 and 20% in mass of ZrO2 in relation to the total mass, with the mixture being formed into a plate via the gel-casting process followed by sintering or controlled cold isostatic compression, and with the plate (or platelets resulting from the division of the plate) being mechanically honed to produce the cutting edge.
