Abstract

Provided is a veined end mill tool blank including a body having at least one cutting edge formed of a veined superabrasive material. An anchoring substrate supports the superabrasive material, the substrate including tungsten carbide (WC). An interface integrally joins the veined superabrasive material with the substrate. For each cutting edge, the tool blank is provided with a slot having a curved surface sintered with the superabrasive material. A locator notch is carved on the veined end mill tool blank relative to the veined superabrasive material as a reference point to aid in locating the superabrasive material on the tool blank. The locator notch engraved on the veined end mill tool blank indicates the location of the superabrasive material on the tool blank, thereby eliminating the need for manually locating coordinates of the superabrasive material during a grinding process by a tool fabricator to achieve a precise grinding.

Abstract

A cemented tungsten carbide body is formed by mixing a tungsten carbide powder and a cobalt powder together to form a powder mixture. The tungsten carbide powder makes up greater than or equal to 80 weight percent of the powder mixture, while the cobalt binder powder makes up about 1.5 weight percent to about 20 weight percent of the powder mixture. Next, the powder mixture is compacted to form a green compact, and a boron nitride coating is applied to a surface of the green compact to form a coated compact. The coated compact is sintered at a temperature sufficient to melt the cobalt powder, such that boron from the boron nitride coating diffuses into the compact and creates a gradient of metallic cobalt and boron extending inward from the surface. The metallic cobalt content increases from the surface inward, while the boron content decreases from the surface inward.

Abstract

A cubic boron nitride particle population having highly-etched surfaces and a high toughness index is produced by blending a reactive metal powder with a plurality of cubic boron nitride particles to form a blended mixture. The blended mixture is compressed to form a compressed mixture. The compressed mixture is subjected to a temperature and a pressure, where the temperature is controlled to cause etching of the plurality of cubic boron nitride particles by reaction of cubic boron nitride with the reactive metal powder, thereby forming a plurality of etched cubic boron nitride particles. Also, the temperature and pressure are controlled to cause boron nitride to remain in a cubic boron nitride phase. Afterwards, the plurality of etched cubic boron nitride particles is recovered from the compressed mixture to form the particle population. Preferably, the particle population contains no hexagonal boron nitride.

Abstract

Diamond particles with enhanced reactivity are used to sinter polycrystalline diamond (PCD), under high pressure and high temperature conditions. Copper and tin form a solution with transition metal catalyst (cobalt) used to sinter diamond particles. Copper and tin enhance the reactivity of the diamond particles, reduce the coefficient of thermal expansion (CTE) mismatch between cobalt and polycrystalline diamond, and lead to a more homogeneous distribution of catalyst metal in PCD. A cutting element may comprise a substrate and a polycrystalline diamond table bonded to the substrate produced by sintering diamond particles with enhanced reactivity mixed with standard diamond particles and chemical additives. These combined effects (more reactive diamond particles, reduced CTE mismatch, and homogeneous distribution of catalyst metal) lead to better performing tools.

Abstract

Polycrystalline diamond cutters have a substrate (110), a diamond body (120) including a planar oriented portion (240) and a projecting portion (250), and a passage (130) extending through the cutter along an axis (140) from an opening in a lower side of the substrate to an opening in a first side of a diamond body. The planar oriented portion of the diamond body is attached to the upper side of the substrate and the projecting portion of the diamond body forms at least a portion of an inner wall surface of the first passage. When mounted on drilling tools, heat generated in the cutters by drilling action is transported away from heat generating regions through the diamond body's contact with fluid medium in the passage as well as through the diamond body itself with the body of the drilling tool functioning as a heat sink. Methods of production of the cutter are also disclosed.

Abstract

Polycrystalline cubic boron nitride compact include a body having sintered microcrystalline cubic boron nitride in a matrix of binder material. The microcrystalline cubic boron nitride particles have a size ranging from 2 microns to 50 microns. The particles of microcrystalline cubic boron nitride include a plurality of sub-grains, each sub-grain having a size ranging from 0.1 micron to 2 microns. The compacts are manufactured in a high pressure - high temperature (HPHT) sintering process. The compacts exhibit intergranular defect formation following introduction of wear. The sub-grains promote crack propagation based on micro-chipping rather than on a cleavage mechanism and, in sintered bodies, cracks propagate intergranularly rather than intragranularly, resulting in increased toughness and improved wear characteristics as compared to monocrystalline cubic boron nitride. The compacts are suitable for use as abrasive tools.

Abstract

Multi-step milling processes to prepare cBN composite powder forms a first powder mixture by adding a binder and a first cBN component, mills the first powder mixture for a first time period, combines a second cBN component with the milled first powder mixture to form a second powder mixture, and mills the second powder mixture for a second time period (less than the first time period) to form the cBN composite powder.

Abstract

A polycrystalline cubic boron nitride (PcBN) is fabricated using a process of overlaying layers of cubic boron nitride (cBN) powder, where the layers have cBN mixed with various concentrations of a ceramic. The process of fabricating the PcBN includes depositing, in a refractory capsule, a carbide, a cubic boron nitride (cBN), and a mixture of cBN and a ceramic, then applying a high pressure and high temperature (HPHT) to the content of the refractory capsule. During the depositing step of the process, the concentration of cBN in the mixture of the cBN and ceramic is lower than the concentration of cBN that is in the layer below it. Upon applying HPHT, the carbide first diffuses across the cBN layer, and then diffuses across the layer with the mixture of the cBN and ceramic. After HPHT ends and the content of the refractory capsule cools, the process yields a PcBN having layers with various concentrations of cBN, and at least one cBN layer with a ceramic material.

Abstract

A method of bonding together components (12,14), such as a tip (12) and a shaft (14) include mutually facing carbide end surfaces is described. The tip (12) includes circumferentially spaced flutes formed in its cylindrical outer periphery. The shaft (14) has a cylindrical outer periphery and a plurality of coolant holes extending through the shaft (14). Bonding of the tip (12) to the shaft (14) is performed by inserting gauge wires (40) into the coolant holes and associated flutes, and positioning brazing material (42) between the first and second end surfaces. A water-soluble bond-blocking material is applied to the gauge wires (40) for preventing brazing of the gauge wires (40) to the brazing material. The brazing material (42) is heated to braze the first and second end surfaces together while the flutes and their associated coolant holes are maintained in alignment by the gauge wires (40). Then, the gauge wires (40) are removed, and residual bond-blocking material is dissolved in water.
