摘要： The present invention relates to a method for the production of tungsten carbide based cemented carbide or cermet tools or components using the powder injection moulding or extrusion method comprising mixing of granulated cemented carbide or cermet powder with an organic binder system whereby the mixing is made by adding all the constituents into a mixer heated to a temperature above the melting temperature of the organic binders. According to the invention the organic binders are added into the mixer, waiting for a melt to form and then slowly adding the cemented carbide or cermet powder into the melt, making sure the temperature does not fall below the melting temperatures of the organic binders.

摘要： A milling cutter includes a body having three cutting edges formed by the body. An end of the body situated opposite the cutting edges defines a fastening end of the milling cutter. Each cutting edge extends from an outer periphery of the body substantially to a center rotational axis of the body along a substantially convexly curved path. Radially outer and radially inner ends of each cutting edge are situated axially rearwardly of an axially foremost point of the cutting edge. Each cutting edge lies on a respective imaginary sphere having a radius which has a center which that is spaced from the cutting edge in a direction toward the fastening end and spaced radially from the center axis.

摘要： A rotary tool such as a helix drill and an end mill for example, is manufactured by forming a blank by an extrusion process, and then sintering the blank. During the extrusion, a mixture is passed through a die which provides a cylindrical shape to the outer peripheral surface of the mixture. A plurality of jaws are disposed downstream of the die for conducting the mixture. Each jaw includes a helical ridge for engaging the outer surface of the extrudate to cause a helical groove to be formed therein which constitutes a chip flute in the tool. During the extrusion, the jaws are moved away from the mixture to terminate formation of the chip groove, whereby a shank portion of the tool is formed.

摘要： A rotary chip-removing tool includes a rotary tool body and a tool tip fastened on a front end thereof. The tool tip is formed of an injection molded body which has an integral cutting edge at its front end, and a coupling structure at its rear end. The coupling structure can be in the form of a threaded hole, or a rearward projection, for coupling the tool tip against the tool body. The tool tip is formed of first and second materials. The first material forms at least part of the cutting edge, and the second material forms the coupling structure. The first material is more brittle than the second material, and the second material is tougher than the first material.

摘要： A tool for chip-forming machining is made by passing first and second compounds through first and second coaxial dies, respectively, whereby the first material forms a center core of the tool, and the second material forms an outer rod of the material. The material of the core is tougher and less wear-resistant than the material of the outer rod. The coaxial first and second compounds are passed through a shaping die and then through a flute-forming structure which forms chip flutes in the outer rod.

摘要： A tool such as a drill or end mill has a central portion formed of a relatively tough hard material connected to an outer peripheral portion formed of relatively wear resistant hard material, i.e., the outer peripheral portion is more brittle and wear resistant than the central portion. The chip flutes of the tool are disposed only in the outer peripheral portion and thus are formed entirely of relatively wear resistant hard material.
