Abstract
The present invention concerns a pressed cutting tool comprising a variable core diameter, a mold and a method for producing the cutting tool by pressing. Said cutting tool preferably comprises a shaft and a part comprising one or more helical flutes, wherein low points or lines in said flutes define the shape of said core. In a preferred embodiment, said core is conical. In a preferred embodiment, said cutting tool is an end mill and/or a drill.
Claims20
A process for manufacturing a product selected from the group consisting of a cutting tool, a blank cutting tool and a precursor cutting tool by pressing, the process comprising:
- providing at least one mold defining the shape of at least part of said product, wherein said mold comprises a mold area and/or cavity comprising ridges designed to define one or more flutes and a core of the product to be produced,
- adding a powder comprising a carbide, ceramic, metal, nitride or cermet powder into said mold,
- exerting a pressure on said powder, thereby producing said product,
- wherein said core is defined by said mold so as to have a variable core diameter.
A pressed product selected from the group consisting of:
- cutting tool, a blank tool and/or a precursor cutting tool, wherein said product comprises a shaft and a cut comprising flutes, wherein said flutes define a core, and wherein said core has a variable diameter.
A mold for producing at least part of a product selected from the group consisting of:
- cutting tool, a blank tool and/or a precursor cutting tool, wherein said mold comprises ridges designed to define flutes and a core of the tool to be produced, wherein said core has a variable diameter.
