An improved polycrystalline diamond composite ("PDC") cutter with secondary PDC cutting surfaces in addition to a primary PDC cutting surface is formed comprising of at least two wafers of cemented carbide bonded together. The secondary cutting surfaces are formed by compacting and sintering diamond in grooves formed at the surface of the wafers. Wafers of different grades of cemented carbide may be used. Moreover, different grades of diamond may be compacted and sintered in different grooves.

A metal cutting insert comprises a carbide substrate, and at least one body of superhard abrasive material, such as PCD or PCBN, bonded to an edge surface of the substrate and extending from one side surface to the other side surface of the substrate. There can be a plurality of superhard bodies disposed at respective corners of the substrate. The abrasive material is applied to the substrate in a container and then sintered and simultaneously bonded to the substrate by an elevated pressure/temperature step. Inserts can be made in rod form (i. e. , in one piece) and then the rod can be transversely sliced into thin inserts; or the inserts can be made in separate pieces, with or without separators within the container.

A method for the removal of solid contaminants which utilizes two rotating mesh screen containers designed to pass the food therethrough while trapping the solid contaminant. The rotation of the first cylindrically-shaped mesh screen causes the food to pass through because of the centrifugal force leaving behind a portion of the solid contaminants. The second mesh or membrane-like placed around the first screen but rotated in the opposite direction is also utilized to trap solid contaminants which are large enough to be trapped by the mesh screen when it is not oriented so as to pass through the screens along its length. Different spacings in mesh and different rotation velocities are utilized to change contaminant screen characteristics.

An improved method and apparatus for the removal of solid contaminants which utilizes at least one rotating mesh screen container designed to pass the food therethrough while trapping the solid contaminant. The rotation of the cylindrically-shaped mesh screen causes the food to pass through because of the centrifugal force. The addition of a second mesh or membrane-like placed around the first screen but rotated in the opposite direction is also utilized to trap solid contaminants which are large enough to be trapped by the mesh screen when it is not oriented so as to pass through the screens along its length. Different spacings in mesh and different rotation velocities are utilized to change contaminant screen characteristics.

156 8927

A method for manufacturing cutting tools having diamond-like cutting edges or surfaces which are formed by bonding high shear compaction diamond or cubic boron nitride (CBN) ropes or strips in helical grooves formed on the cutting tool outer surface. The strips are formed by slitting a sheet of high shear compaction diamond or CBN material. The ropes are formed by rolling the strips between grooved rollers.

According to the present invention there is provided a method of making a cutting insert with a hole for clamping to a tool holder wherein a super-hard abrasive material is sintered and simultaneously bonded to a sintered cemented carbide body with a hole inside a container under elevated pressure and temperature conditions. During sintering the hole is filled with a plug which after sintering is removed.
