A related cutting insert includes: a cutting insert body having a plurality of cavities formed therein; a plurality of cutting tips, each of the plurality of cutting tips disposed in a respective cavity, the cutting tips having a geometry that provides a mechanical retention or lock when inserted into the cavities of the cutting insert body, the cutting tips further being brazed in the cutting insert body. | 09-04-2008 |
| 20090269151 | UNCOATED CUTTING TOOL USING BRAZED-IN SUPERHARD BLANK - An uncoated cutting tool that comprises a body containing a pocket. A polycrystalline cubic boron nitride blank has a cutting tip. The blank is brazed into the pocket using a braze alloy whereby there is a braze joint between the body and the polycrystalline cubic boron nitride blank. The braze alloy has a liquidus temperature of at least about 900 degrees Centigrade wherein the braze alloy is selected from the group comprising a nickel-gold braze alloy containing nickel and gold, a copper-gold braze alloy containing copper and gold, a silver-titanium braze alloy containing silver and titanium, and a silver-palladium braze alloy containing silver and palladium. | 10-29-2009 |
| 20100202840 | CUTTING TOOL, METHOD OF FORMING CUTTING TOOL, AND METHOD OF MANUFACTURING CUTTING TOOL - A cutting tip including a cutting edge portion made of a high-hardness material to take a thin-plate shape; and a support portion made of a material which is more worn in contact with a workpiece than the cutting edge portion not to exert a machining action on the workpiece even in contact with the workpiece, and securing and supporting the cutting edge portion on a reverse side of a rake face of the cutting edge portion. Thus, the width of flank wear is prevented from increasing and chipping of the cutting edge is prevented, so that the life of the cutting tip can be extended. | 08-12-2010 |
| 20100272527 | METHOD TO ATTACH OR IMPROVE THE ATTACHMENT OF ARTICLES - The disclosure relates to articles including a first material and a second material, wherein attachment between said first material and said second material is improved or created by gas-phase deposition and/or reaction to form new and adhesive solid phase(s) between the first material and the second material. | 10-28-2010 |
| 20110020082 | JOINED PRODUCT - There is provided a joined product suitable as a cutting tool that is fit for high-speed cutting, CVD coating process and the like, and does not cause a reduction in joint strength of a joining layer even if a high temperature exceeding a temperature at which a brazing filler forms the liquid phase is reached during cutting. Specifically, the joined product includes a cemented carbide sintered compact serving as a first material to be joined and a cBN sintered compact or a diamond sintered compact serving as a second material to be joined. The first material to be joined and the second material to be joined are joined by a joining material that does not form a liquid phase at a temperature lower than 1000° C. and that is placed between the first material to be joined and the second material to be joined. The joining is performed by resistance heating and pressing at a pressure of 0.1 to 200 MPa. | 01-27-2011 |
| 20120282050 | SURFACE-COATED SINTERED BODY - There is provided a surface-coated sintered body formed of a sintered body of cubic boron nitride with a sufficiently adhesive surface coating layer thereon. The present surface-coated sintered body includes a sintered body of cubic boron nitride and a surface coating layer formed on a surface thereof, the sintered body of cubic boron nitride including 20-99.5% by volume of cubic boron nitride and a binder, the surface coating layer including an adhesion layer and at least one hard coating layer, the adhesion layer being a metal layer including at least W, and being formed to cover a surface of the sintered body of cubic boron nitride, the hard coating layer being formed to coat the adhesion layer, the adhesion layer being configured of an amorphous state and/or ultrafine particles having an average particle size equal to or smaller than 5 nm. | 11-08-2012 |
| 20130121777 | CUTTING TOOL HAVING AT LEAST PARTIALLY MOLDED BODY AND METHOD OF MAKING SAME - A cutting tool for performing cutting operations on a workpiece when the cutting tool is rotated about a central axis by a machine tool, the cutting tool includes a generally cylindrical body disposed about the central axis. The generally cylindrical body includes a first end and an opposite second end. The cutting tool further includes a cutting portion and a mounting portion. The cutting portion is disposed at or about the first end of the generally cylindrical body and includes a number of cutting edges structured to engage the workpiece during cutting operations. The mounting portion is disposed at or about the opposite second end of the generally cylindrical body and is structured to be coupled to the machine tool. At least a portion of the generally cylindrical body comprises a molded portion formed via a molding process about the cutting portion in a manner that couples the cutting portion to the generally cylindrical body. | 05-16-2013 |
| 20130343826 | CUTTING TOOL INSERT WITH POWDER METAL INSERT BODY - A method of making a cutting tool insert, including positioning and fixing an abrasive tip in a mold, filling the mold with a powder metal mixture, and infiltrating the powder metal mixture around at least a portion of the tip to define a green body. The method further includes compacting the powder metal to define a pressed green body, sintering the pressed green body to yield a sintered body having a metallic portion and a tip portion, and cooling the sintered body to put the tip portion into compression. The tip portion is non-adhesively mechanically attached to the metallic portion. | 12-26-2013 |
| 20140212233 | CUTTING INSERT - A cutting insert has only cutting edge portion thereof made of SiC whisker reinforced ceramics brazed to the shank with active solder. This provides improved cutting performance by increased toughness and high strength of the SiC whisker reinforced ceramics without limitation in shape while reducing manufacturing costs. The cutting insert includes a cutting edge portion made of SiC whisker reinforced ceramics, and a shank to which the cutting edge portion is mounted. The cutting edge portion is brazed to the shank using an active solder, and the whiskers are disorderedly arranged and agglomerated in the cutting edge portion. | 07-31-2014 |
| 20160144468 | METHOD OF MANUFACTURING CEMENTED CARBIDE CUTTING TOOL AND CUTTING TOOL MANUFACTURED BY THE METHOD - Method of manufacturing a cemented carbide cutting tool, includes a) bonding a body part of hot work tool steel and a cutting part of cemented carbides together by heat treatment; b) cooling the bonded body part and cutting part for a preset period of time; c) machining the cutting part to have a predetermined pattern according to its application and forming a cutting tool; d) coating a surface of the machined cutting tool with a film of at least one of metallic oxides, nitrides and carbides; and e) cooling the coated cutting tool for a preset period of time in air, and a cutting tool manufactured by the method. Cracks do not generate even after the coating step, and thus cemented carbide cutting tool having excellent mechanical properties may be manufactured. | 05-26-2016 |
