A superhard element () for a machine tool, comprising polycrystalline cubic boron nitride (PCBN) material containing whiskers of a ceramic material, the PCBN material comprising at least about 50 volume percent cubic boron nitride (cBN) material dispersed in a binder matrix comprising a compound including titanium and the whiskers; the content of the whiskers being at least 1 weight percent and at most 6 weight percent of the binder matrix.

Superhard element, method of using same and method of making same

PCBN material consisting essentially of cubic boron nitride (cBN) grains and binder material, the content of the cBN grains being at least 80 weight percent of the PCBN material; the binder material comprising greater than 50 weight percent Al and a combined content of at least 5 weight percent of an iron group element and a refractory element, the iron group element selected from the group consisting of Co, Fe, Ni and Mn, and the refractory element selected from the group consisting of W, Cr, V, Mo, Ta, Ti, Hf and Zr.

PCBN material, tool elements comprising same and method for using same

A method of producing a tool insert which comprises a central metal portion having edge regions of superabrasive material bonded thereto and presenting cutting edges or points for the tool insert is disclosed. A body () having major surfaces on each of opposite sides thereof, each having spaced strips () of superabrasive material, typically abrasive compact such as PCBN or PCD, for example, separated by a metal region or regions, such as cemented carbide, is provided. Each superabrasive strip of one major surface is arranged in register with a superabrasive strip of the opposite major surface. Alternatively, each superabrasive strip extends from one major surface to the opposite major surface. The body is severed from one major surface to the opposite major surface along at least two sets of planes intersecting at or in the respective superabrasive strips to produce the tool insert.
