| An insert made of an ultra-high-pressure sintered compact and including no base metal or support layer is brazed to a tool body under vacuum by use of a Ti-containing activated silver brazing filler metal. This method permits the insert to be securely fixed to the tool body without fear of the insert coming off the tool body even if the tool is a helical one. Because no base metal layer is needed, the manufacturing yield, efficiency and productivity are improved. | ||||||

| A cemented carbide ball end mill comprises a cutting portion with a semi-spherical ball portion at a tip thereof, and has a following configuration. When an intersection line between a cutting edge rake face and a chip evacuating flute at the ball portion is projected on a plane which includes a central axis of the ball end mill and is parallel with a cutting edge at the central portion of a ball portion tip, projected on the plane is a convex-curved line or a straight line. An angle formed by the straight line connecting a vertex of the ball portion, where the intersection line passes through, and the other end of the intersection line with respect to the central axis is from 30null to 50null. Further, an angle formed by the rake face and the chip evacuating flute is from 100null to 150null, and a width of the chip evacuating flute is 0.5 to 5 times as large as a radius of the ball portion. On the cutting portion, a coating film of titanium carbide or the like is formed as a first layer, and another coating film of a silicon carbide system amorphous film or the like having a physical property similar to that of diamond is added as a second layer. The cemented carbide ball end mill suffers less deposition of melted metal even when dry-cutting an aluminum alloy, has a long service life, and enables the machining providing an excellent surface property. | ||||||

The removal of oxygen can be effected by directing a stream of nitrogen into the interface. | ||||||
| 14 | Manufacture of rotational cutting tool, super high pressure sintered body helical chip and tool thereof for the rotational cutting tool, and chip | JP10090395 | 1995-04-25 | JPH0885012A | 1996-04-02 | ABE MAKOTO |
| PURPOSE: To manufacture a high-performance, high processing accuracy and long life rotational cutting tool at a low cost which is capable of brazing on the tool body a bed plate less helical chip composed of a superhigh pressure sintered body and having its cutting edge composed of a large helix angular superhigh pressure sintered body helical chip. CONSTITUTION: Adherence of a superhigh pressure sintered body chip 1 not containing a bed plate to a tool body 2 is accomplished by a method of brazing in a vacuum, using a Ti inclusion active silver solder material. This method allows the chip 1 to solidly adhere to the tool body 2 through an adhesive layer 3 of the Ti inclusion active silver solder material and chip is never removed even if it is a helical chip. Since the bed plate is dispensable, improvement of chip manufacturing yield rate and manufacturing efficiency, reduction of tool machining cost, improvement of productivity, and the like can be realized. | ||||||
| 15 | Throwaway tip for milling cutter tool | JP9239394 | 1994-04-28 | JPH07299636A | 1995-11-14 | YAMAYORI TSUTOMU |
| PURPOSE:To smoothly discharge chips by making an edge angle of cutting edges small, and reduce cutting resistance by making an entering angle of the cutting edges to a work small, by forming plural noncutting recessed parts and a positive face angle having a specific angle range to the cutting edges. CONSTITUTION:In a throwaway tip 1 for a milling cutter tool, a plane shape is molded in a rhombic plate shape. In this case, respective cutting edges 2 are respectively formed in crossing parts between a long piece of an upper surface and both side surfaces in the tip 1, and noncutting recessed parts 3 of l to 4 pieces are respectively formed on the respective cutting edges 2, and a face angle of 2 deg. to 30 deg. is formed. According to this, an edge angle of the cutting edges 2 can be made small, and chips having a small thickness can be formed, and these chips can be smoothly discharged, and the chips are not entwined between the cutting edges 2 and a work. Since an entering angle of the cutting edges 2 to the work is small, cutting resistance can be reduced, and chatter vibration can be reduced, and a cutting surface can be smoothed. | ||||||

| PURPOSE: To enable hard vapor deposition layers to exhibit excellent separation resistance even when they are used in high feed cutting or high notch cutting by making the outermost side unit hard vapor deposition layer equal to a single unit hard vapor deposition layer among plural unit hard vapor deposition layers. CONSTITUTION: A bottom edge on a tip surface of a cutting edge part and a flank relief 3a of an outer peripheral edge 3 to similarly form a cutting edge part are covered with a single unit hard vapor deposition layer T 1. A part except to form the single unit hard vapor deposition layer in this cutting edge part is covered with plural unit hard vapor deposition layers T 1 to T 4, and among the plural unit hard vapor deposition layers, the outermost side unit hard vapor deposition layer T 1 is made equal to the single unit hard vapor deposition layer. These unit hard vapor deposition layers are formed of a single kind of single layer or two or more kinds of plural layers among Ti, TiC, TiN, TiCN, (Ti, Ab) N, (Ti, Al) CN and Al 2O 3. Thereby, the hard vapor deposition layers exhibit excellent separation resistance. COPYRIGHT: (C)1995,JPO | ||||||
