This disclosure relates to a high cBN content polycrystalline cubic boron nitride, PCBN, material. The binder matrix material comprises 19 to 50 wt. % chromium, or a compound thereof.

Polycrystalline cubic boron nitride material

A cutting insert for a cutting tool includes a body having a cutting edge, a rake face, and micro channels provided on the rake face adjacent the cutting edge. The micro channels define a grid pattern of micro channels that intersect each other in a region of the rake face where contact between a chip and the rake face is assumed to occur during cutting with the cutting insert.

Cutting insert

A cutting tool insert for machining by chip removal includes a body of polycrystalline cubic boron nitride compact (PCBN), either as a solid insert or attached to a backing body, onto which a hard and wear resistant PVD coating is deposited. The coating includes a polycrystalline nanolaminated structure of alternating A and B layers, where layer A is (Ti,Al,Me1)N and Me1 is one or more of the metal elements from group 3, 4, 5 or 6 in the periodic table, layer B is (Ti,Si,Me2)N and Me2 is one or more of the metal elements from group 3, 4, 5 or 6 in the periodic table including Al with a thickness between 0.5 and 10 &#x3bc;m. The insert is particularly useful in metal cutting applications generating high temperatures, e.g., high speed machining of steels, cast irons, super alloys and hardened steels.

Nanolaminated coated cutting tool

A cutting tool insert for machining by chip removal includes a body of a hard alloy of cemented carbide, cermet, ceramics, cubic boron nitride based material or high speed steel, onto which a hard and wear resistant coating is deposited by physical vapor deposition. The coating includes a polycrystalline nanolaminated structure of alternating layers A and B where layer A is (Ti,Al,Me1)N and Me1 is optionally one or more of the metal elements from group 3, 4, 5 or 6 in the periodic table, layer B is (Ti,Si,Me2)N and Me2 is optionally one or more of the metal elements from group 3, 4, 5 or 6 in the periodic table including Al with a thickness between 0.5 and 20 &#x3bc;m and method of making the same. This insert is particularly useful in metal cutting applications generating high temperatures with improved edge integrity, machining of super alloys, stainless and hardened steels.

Coated cemented carbide inserts are particularly useful in general turning of superalloys. The inserts are formed from a cemented carbide of WC about 5.0-7.0 wt-% Co, and about 0.22-0.43 wt-% Cr, where the substrate has a coercivity (Hc) of about 19-28 kA/m. The coating contains a single layer of (TiAl)N-layer, where x is 0.25-0.50, with a crystal structure of NaCl type, a total thickness of about 3.0-5.0 &#x3bc;m, (200)-texture, and a compressive residual strain of about 2.5&#xd7;10-5.0&#xd7;10, optionally containing an outermost TiN-layer.
