摘要: A method is provided which bonds a composite abrasive compact to a cemented carbide pin. The method includes the steps locating a braze alloy having a perforated metal material embedded therein between a surface of the composite abrasive compact and a surface of the cemented carbide pin. The braze alloy has a melting point below that of the metal material. The surfaces are urged together, the temperature of the braze alloy is raised to above its melting point and maintained at this temperature for a short period. The alloy is then allowed to cool and solidify and bond the surfaces together.

摘要: A tool insert having a cemented carbide substrate with a recess formed in one end of the substrate and having an abrasive compact located in the recess and bonded to the substrate. The cemented carbide substrate has two ends joined by a side, and the recess formed in the substrate has a side and a base, with the side sloping inwards towards a center point of the base. The abrasive compact includes a top surface which provides a cutting surface or edge for the tool insert, a bottom surface which is complementary to the base of the recess, and a side surface which is complementary to the side of the recess.

摘要: In the brazing of a component which comprises a carbide substrate carrying a layer of PCD (polycrystalline diamond) to a steel body, appropriately shaped brazing shims are placed between mating surfaces which are to be brazed. The component is forced towards the steel body and the steel body is heated uniformly across its surface where brazing is to take place. This is achieved by means of an induction heater placed adjacent the steel body at a position remote from that surface of the steel body where brazing is to take place. The local temperature at the PCD layer is monitored continuously and the heating process controlled so that this local temperature does not exceed 750.degree.. After brazing, the component and steel body are permitted to cool down slowly to ambient temperature.

摘要: A spring clip which is used to secure the shank of a cutting pick to a pick box or cutting drum in a mining machine. The clip is formed of spring steel and has spaced legs joined by a bight portion. Associated with the bight portion is a bearing part which bears upon the shank of the cutting pick when the clip has been aligned with the shank and has been forced transversely to the shank so that the shank is received between the legs.
