    Abstract: A tool for machining parts and particularly surfaces of parts includes a machining head and a main, supporting body (3) made of carbon fibers bonded by a polymer binder and additionally contains polyhedral multilayer carbon nanostructures of the fulleroid type having e.g. a layer-to-layer distance of 0.34-0.36 nm, taken in a quantity of 0.05-50 wt % of the mass of the polymer binder. The main body thereby obtains an increased stiffness and strength.

    Abstract: The invention discloses a metal-bonded diamond grinding wheel prepared by self-propagating pressure-less sintering and a preparation method thereof. The metal bonded diamond grinding wheel mainly comprises a working layer and a non-working layer, wherein the working layer comprises metal bond and grinded diamond, the non-working layer is metal bond, and the metal bond in the working layer and non-working layer have the same components that comprise metal powders of Cu, Al, Ni, Ti, Sn, and Co. To prepare the metal-bonded diamond grinding wheel prepared by self-propagating pressure-less sintering solves the problems of high energy consumption and low manufacture efficiency in the current sintering processes of the metal bonded diamond grinding wheel, and improves the binding force of the metal bond to the grinded diamond by forming carbides between the bond and the grinded diamond.

    Abstract: Bonded abrasive tools, e.g., grinding wheels, can be reinforced using, for instance, one or more fibreglass web(s) having a surface of glass per unit of at least 0.2. Alternatively or in addition, the fibreglass web has a thickness of 2 mm or less. The web can be designed to provide improved adhesion between the fibreglass reinforcement and the mixture employed to form the bonded abrasive tool. In some examples, the middle reinforcement at the neutral zone of the wheel can be eliminated or minimized.
