Patent number: 8091459Abstract: A method for manufacturing a rotary tool for chip removing machining with at least one chip flute that extends in the longitudinal direction of the tool. The method involves preparing a mixture of a cemented carbide, cermet or ceramics powder and a carrier, such as a polymer, and placing the mixture in an extruding machine. The mixture is extruded in a feed direction by means of a die to form the diameter of the mixture body. The mixture body passes against a chisel which forms a chip flute in the outer periphery of the mixture body by chip-removing machining. When the chisel is displaced away from the mixture body, a non-fluted shaft portion is formed. By rotating the mixture body while contacted by the chisel, a helical chip flute can be formed. Alternatively, the body could be twisted after a straight flute has been formed, whereupon the flute becomes helical.Type: GrantFiled: December 28, 2007Date of Patent: January 10, 2012Assignee: Sandvik Intellectual Property AktiebolagInventors: Jören Kugelberg, Roine Ericsson, Jonathan Fair, Anders Micski

Method of making a cemented carbide powder mixture and the resulting cemented carbide powder mixture
Patent number: 7387658Abstract: A method of making cemented carbide at which powders forming hard constituents and powders forming binder phase are wet milled together with a pressing agent is disclosed. The slurry is dried, preferably by spray drying, compacted into bodies of desired shape and sintered. A cemented carbide powder with a reduced compacting pressure at a predetermined weighing in of 18% shrinkage can be obtained by using from about 1 to about 3 wt-% pressing agent with the following composition: less than about 90 wt-% PEG and greater than about 10 wt-% of long chain C?20 fatty acids, their esters and salts, in particular, erucic acid and/or behenic acid. The invention also relates to a cemented carbide powder with low compaction pressure.Type: GrantFiled: June 22, 2006Date of Patent: June 17, 2008Assignee: Sandvik Intellectual Property ABInventors: Alistair Grearson, Jonathan Fair, Rickard Sandberg -

Patent number: 7296497Abstract: The present invention relates to a method for manufacturing a drill blank or a mill blank by extrusion, said method comprising the forming of a first blank portion (B1) having external, axially extending external flutes and the forming of a further blank portion (B3) in the shape of a shaft. The invention also relates to a device for manufacturing a drill blank or a mill blank. The method according to the invention is characterised by: extruding a first blank portion (B1) having a free end and external flutes; allowing the extrusion to continue to supply further extruding mass into a cavity (6), said supply of extruding mass completely filling out the external flutes of the first blank portion (B1) to produce a second blank portion (B2) integral with the first blank portion (B1); allowing the extrusion to continue to produce a desired length of the first blank portion (B1); and cutting off the first blank portion (B1) at the end facing away from the second blank portion (B2).Type: GrantFiled: May 4, 2005Date of Patent: November 20, 2007Assignee: Sandvik Intellectual Property ABInventors: Jörgen Kugelberg, Roine Ericsson, Jonathan Fair, Anders Micski
