  • Manufacturing of components for valve mechanisms for internal combustion engines
    Patent number: 7052637
    Abstract: A method for fabricating components such as rocker arms (4), cam followers (3) or cams for valve mechanisms for combustion engines, in which a billet of an MMC material (Metal Matrix Composite) containing 10–70% ceramic material by volume in the form of particles or fibers is extruded into a bar (1, 2) having the cross-sectional profile of the final component (3, 4), and where separate billets for the respective components (3, 4) are obtained by cross-cutting the bar (1, 2) by means of cutting via high-speed machining, HSM.

  • Bearing reinforcement in light metal housing
    Patent number: 6779245
    Abstract: Bearing reinforcement for a shaft (3) mounted in bearings in a cast light-metal housing (1, 2) such as an engine block or a gearbox housing, in which an insert (5) that forms a bearing seat for the shaft (3) is made of an MMC material, i.e. a metal matrix composite, and in which the base material of the MMC material consists of the same metal as the metal that comprises the principal component in the light-metal housing, wherein the MMC material of the insert (5) is reinforced with 10-70% ceramic material by volume in the form of particles or fibers. The invention also describes a method for fabricating inserts (5) in which they are formed into a bar having the same cross-section as the radial cross-section of the insert, whereupon separate inserts are cross-cut from the bar by means of high-speed machining or water cutting.

  • Machining of MMC material
    Patent number: 6293741
    Abstract: A component made from a material of metal matrix composite, a so-called MMC material, is manufactured by High Speed Machining, so-called HSM machining, of a workpiece or blank of MMC material to provide a predetermined shape. HSM machining is characterized in that the cutting tool operates at a very high speed in relation to the machined work piece, especially as compared to what is normally the case when using conventional machining techniques.
