摘要： The present invention relates to a tool and a tool tip for chip removal, wherein the tool in operative position preferably rotates around its longitudinal centre axis. The tool tip (10") contains two hard metal grades, a tough, less wear resistant grade in the inner portion (40") and a more brittle, more wear resistant grade in the external portion (41"). The tool tip is made from two grades that have the same shrinkage. The inner portion (40") is entirely surrounded by the external portion (41") except for in the feed direction and the retraction direction. The tool tip has a thread (25) formed in the tougher hard metal such as to endure high tensions.
摘要翻译：用于排屑的工具和工具尖端技术领域本发明涉及一种用于排屑的工具和工具尖端，其中处于工作位置的工具优选围绕其纵向中心轴线旋转。刀尖（10“）包含两种硬金属牌号，内部（40”）的坚硬耐磨等级较低，外部（41“）的耐磨等级更加脆弱和耐磨。刀尖为由两个具有相同收缩率的等级制成，除了在进给方向和退回方向上以外，内部部分（40“）完全被外部部分（41”）包围。更强硬的金属，例如以承受高度紧张。

摘要： The present invention relates to a tool and a cutting portion for cutting machining, wherein the tool in operative position preferably rotates about its longitudinal center axis. The tool comprises a tool body (12), a cutting portion (10) and a pull rod (11), said tool body having a front surface and said cutting portion having a support surface provided to dismountably abut against each other. The body has a shank portion (40). The front surface and the support surface comprise cooperating projections and recesses, which are provided to substantially alone transfer the cutting forces appearing during machining. The invention also relates to a separate tool tip, a cutting portion, a tool body as well as to a method for manufacturing a tool tip or a cutting portion.

摘要： The present invention relates to preparation, handling, and spray drying, in an economic and environment-friendly way, of slurries for the production of tungsten carbide based hard metal tools or components by the powder injection moulding or extrusion route. The slurry used is based on ethanol-water and contains metal carbide and metallic raw materials as well as stearic acid and a low concentration of polyethylenimine (PEI). The concentration of PEI is 0.01-1 wt% of the raw material weight. This combination results in low-viscous slurries, which require less use of ethanol, energy, manpower, and equipment time in their preparation, handling, and spray drying. The invention also relates to the powder obtained by using the method.

摘要： The present invention relates to a method of making a sintered body comprising one or more hard constituents in a binder phase by injection moulding or extrusion. According to the invention, the binder system consists of 30-70 wt-% poly(ethylene-co-vinylacetate) and balance a (Polyethylene)-blend-(Poly(oxy-1,2-ethanediyl), .alpha.-hydro-.omega.-hydroxy)-based wax. The solids loading of the feedstock, γ, is 0.51 γ = ρ f - ρ b ρ s - ρ b where
ρ s is the density of the material as sintered,
ρ b is the density of the binder system and
ρ f is the density of the feedstock, measured with a helium pycnometer. Debinding is performed by heating in a furnace in flowing hydrogen atmosphere.
