| PURPOSE:To implant inserts to a cone body in the stage of casting the cone body by disposing preliminarily the many inserts in the prescribed positions of a casting mold and embedding the inserts by casting thereby forming teeth. CONSTITUTION:A casting mold surface 12 having an outside shape united with a cone body and tooth 5 is formed to a casting mold 10 and insert materials consisting of a sintered hard alloy are inserted and held in the recesses corresponding to the teeth 5 in the stage of producing the cone of a drill bit by centrifugal casting. While the mold 10 is rotated around a shaft 11, a molten metal is cast therein and the parts of the inserts 5 projecting inward from the surface 12 are embedded by casting of the body, by which the desired drill bit cone is obtd. The inserts having excellent performance are thus surely held into the cone body of the drill bit by the simple method. | ||||||

| PURPOSE:To obtain easily a cutter ring for a tunnel excavating machine having improved wear resistance in the outside circumferential part by charging a molten metal contg. sintered hard particles into the product cavity of a casting mold while rotating said mold. CONSTITUTION:A molten metal contg. sintered hard particles of tungsten carbide, etc. is charged through a runner 7 into a product cavity 6 of a casting mold 5 while a rotary disc 1 is rotated to keep the mold rotation. The metal charged into the product cavity 6 is pressed to the outside circumferential surface 6a of said cavity by contrifugal force and since the sintered hard particles having the heavier specific gravity are gathered near the surface 6a, a cutter ring A dispersed and embedded by casting with the sintered hard particles in the outside circumferential part A' is obtd. The slag and gas having the smaller specific gravity are gathered to the inside and the defect-free cutter ring for the excavating machine is produced. | ||||||

| PURPOSE:To reduce the number of steps in the manufacture of molding dies by driving plural pieces of anchor bolts to a die body of molding dies, enclosing these with plastics, setting these in molding flasks and substituting the plastics with molten metal. CONSTITUTION:Plural pieces of anchor bolts 8 are properly drirven to a die body 1 manufactured by casting or forging, and are enclosed by an expanded polystyrene 3. The polystyrene 3 is set on a molding board, and the circumference thereof is enclosed with a die flask 4. Molding sand 5 is put therein and is compacted. The flask 4 is turned over, and a top part flask 6 is placed thereon, and again sand is packed. A runner 9 and a riser 10 are provided. The body 1 is beforehand preheated, and molten metal 11 is charged through the runner 9 to substitute the polystyrene 3 with the molten metal 11. Upon cooling of the charged molten metal, the flasks 4, 5 are removed and the casting plan parts are cut off, whereby the one piece molding die cast with the body 1 in the die base part 2 is obtained. | ||||||

| PURPOSE:To obtain composite dies of high quality by mounting the investment of cavity parts having an arbitrary shape and a constant wall thickness at the center of die pack materials, casting molten metal and dividing the die pack materials to top and bottom parts after the casting. CONSTITUTION:Investment 1 of cavity parts having a constant wall thickness along the shape of the cavity parts is installed to the central part of die pack materials 2 and molten metal is cast therein. After the completion of the casting, the materials 2 are finished by machining, then the materials 2 are parted from the center of a parting margin 3, whereby they are bisected to a top part and a bottom part. Then the matching characteristic between the top part and the bottom part is exceedingly excellent, and there are no un-melt-stuck parts in the boundary parts between the cavity members 1 and the materials 2, and these parts are thoroughly and uniformly melt stuck. | ||||||

An apparatus and method for manufacturing a downhole tool that reduces failures occurring along a bondline between a cemented matrix coupled around a blank. The cemented matrix material is formed from a tungsten carbide powder, a shoulder powder, and a binder material, wherein at least one of the tungsten carbide powder or the shoulder powder is absent of any free tungsten. The blank, which optionally may be coated, is substantially cylindrically shaped and defines a channel extending from a top portion and through a bottom portion of the blank. The absence of free tungsten from at least one of the tungsten carbide powder or the shoulder powder reduces the reaction with iron from the blank, thereby allowing the control and reduction of intermetallic compounds thickness within the bondline.
