Abstract
A cutting tool with a device for the prevention of uncontrolled chip formation which are placed in a specific distance to a cutting edge at a layer of polycrystalline diamond (PCD) or polycrystalline boron nitride (PCBN), and to a manufacturing process for the production of such a cutting tool. The PCD or PCBN layer incorporates the device for the prevention of uncontrolled chip formation as an integral part, and the layer with the device for the prevention of uncontrolled chip formation and the cutting edge are produced by way of an additive procedure, or that the device and the cutting edge are produced by removing material of the PCD or PCBN body by laser or electro-erosion.
Claims9
Cutting tool insert (14, 36) with means (24, 42) for the prevention of uncontrolled chip formation arranged in a specific distance to the cutting edge (26, 44) at a layer (22, 40) of polycrystalline diamond (PCD) or polycrystalline boron nitride (PCBN) within the area of a cutting surface (28, 46), and preferably arranged on a supporting body (20, 38), wherein said PCD or PCBN layer (22, 40) incorporates the means (24, 42) for the prevention of uncontrolled chip formation as an integral part and wherein said layer (22, 40) with said means (24, 42) for the prevention of uncontrolled chip formation and said cutting edge (26, 44) are produced by way of an additive procedure or that said means (24, 42) for the prevention of uncontrolled chip formation and said cutting edge (26, 44) are produced by removing material of the PCD or PCBN body by laser or electro-erosion.
Procedure for the manufacturing of a cutting tool insert (14, 36) with means (24, 42) for the prevention of uncontrolled chip formation arranged within the area of a cutting surface (28, 46) and in a specific distance to a cutting edge at layer (22, 40) of polycrystalline diamond (PCD) or polycrystalline boron nitride (PCBN), and preferably arranged on top of a supporting body (20, 38), wherein said PCD or PCBN layer (22, 40) and said means (24, 42) for the prevention of uncontrolled chip formation are formed as integral parts whereby layer (22, 40) with said means (24, 42) for the prevention of uncontrolled chip formation and said cutting edge (26, 44) are produced by way of an additive procedure and whereby said means (24, 42) for the prevention of uncontrolled chip formation and cutting edge (26, 44) are produced by removing material of the PCD or PCBN body by laser or electro-erosion.
