Definitions

  • the present invention relates to cutting inserts having cutting edges formed from a superhard abrasive material.
  • Indexable cutting inserts typically have a polygo- nal shape with a superhard material disposed generally at the corners.
  • the superhard material often a cubic boron nitride or polycrystalline diamond material, aids in the cutting of hard work piece materials such as metals.
  • These cutting inserts are typically mounted in a fixed position to a cutting tool so as to present one of the corners or areas containing superhard material to the surface of a work piece. After being used for a period of time, the area of superhard material becomes worn.
  • a stacked structure is formed comprising a first layer of hard backing material and a layer of superhard cutting material superimposed onto the backing layer. Cutting tips are then cut from this stacked structure and brazed to a cutting insert body, typically at a corner thereof U.S. Patent No. 5,183,362.
  • the braze joint connecting the cutting tips to " The " body of the cutting insert creates an inherent weak point in the structure. This is particularly true due to the high temperatures that tend to exist during use of such cutting inserts, these high temperatures being in close proximity to the braze joint. In addition relatively complex fixtures have to be used during the brazing process.
  • a second technique for forming indexable cutting inserts involves providing a blank or substrate having pockets formed therein which are filled with superhard material, then subjecting the blank to a sintering operation which bonds the superhard material to the substrate. The blank is then subsequently machined to give the cutting insert its final shape, i.e. - a generally polygonal body with superhard material disposed at the corners thereof, U.S. Patent No. 5,676,496.
  • French Patent Publication No. 2,691,657 discloses a cutting insert made with a special autocentering shape made of polycrystalline diamond, CBN or other cutting material. The insert is clamped into the tip by a spring without brazing. French Patent Publication No. 2,706,339 also discloses an insert of similar materials of a shape (including securing lugs) such that the insert can be secured in the corresponding hole in the tip by a mechanical wedging without brazing.
  • WO 2004/105983 discloses cutting insert including: 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 symmetric 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.
  • Figure 1 is a top view of a cutting insert formed according to the present invention wherein black areas indicate superhard material.
  • Figures 2A and 2B are top views showing details of the geometry of a cutting tip formed according to the present invention.
  • Figures 3A-3G are top and side views of various cutting tips formed according to the present invention.
  • Figures 4A and 4B are a top view of a threading and thread-milling insert, respectively, formed according to the present invention.
  • Figure 5 is top view of another type of threading insert formed according to the present invention.
  • Figures 6A-6E are top and three side sections of other inserts formed according to the present invention.
  • Figures 7A and 7B are side cross-sectional view and top view, respectively, of a drill formed according to the present invention.
  • Figures 8A, 8B and 8C are side cross-sectional views of drill configurations formed according to the present invention.
  • Figure 9 is a side view of a tool which can be used for internal turning, boring, slotting or parting formed according to the present invention.
  • Figure 10 is side view of a parting and grooving tool formed according to the present invention.
  • Figure 11 is top view of a tool formed according to the present invention.
  • Figure 12 is a top view of a blank comprising a number of pockets filled with superhard material and cut lines for removal of a plurality of cutting tips therefrom.
  • the cutting inserts 60 for turning, milling, drilling or other machining applications consisting of at least one cutting tip 20 and an insert body 32 are illustrated in Fig. 1.
  • the cutting tips have a geometry that provides a mechanical retention or lock when inserted into cavities of the insert body.
  • the cutting tips 20 are affixed to the cavities is the body 32 by any suitable technique along an interface 40. Suitable techniques include gluing, soldering or brazing.
  • the cavities are preferably provided with a shape or geometry that is complimentary to the shape or geometry of the cutting tips disposed therein. As illustrated in Fig. 1 the cutting tips in top surface plane of the cutting insert are either symmetric 2Ox and asymmetrically arranged in the insert or they are asymmetric 2Oy in at least one way.
  • At least one of the cutting tips is arranged asymmetrically about a bisector through the corners of the cutting insert body and/or at least one of the cutting tips is asymmetric about a bisector through the top surface plane of the cutting tips and/or at least one of the cutting tips is asymmetric in the cutting edge portion about a line symmetrically dividing the anchor portion of the cutting tips and/or at least one of the cutting tips is asymmetric in the rearward anchor portion about a line symmetrically dividing the cutting edge portion of the cutting tips and/or at least one of the cutting tips is asymmetric in the plane sym- metrically dividing the cutting tips between a top surface and a bottom surface.
  • Cutting tips 20 comprehended by the present invention is illustrated in Figure 2A (symmetric) and 2B (asymmetric) .
  • a pair of converging forward surfaces 22a and 22b meet at a forward nose 24, which is preferably rounded.
  • the nose 24 is presented to the work piece during use of the cutting tip.
  • at least a portion of the surfaces 22a and 22b, and the nose 24 comprise superhard cutting material 16.
  • Moving in the direction away from the forward nose 24, subsequent to the converging surfaces 22a and 22b is an area of reduced width or a waisted section 25.
  • the waisted section is defined by a first pair of angled surfaces 26a and 26b, as well as a second set of surfaces 28a and 28b.
  • Surfaces 26a and 28a, as well as 26b and 28b meet at the area of reduced width and define a trough-like formation giving an essentially trapezoidal shape.
  • the surfaces denominated x a' and x b' can be of the same length as shown in Fig. 2A or of different lengths and shapes as shown in Fig. 2B.
  • the base portion 29 is substantially flat, but other shapes are possible including oval, circular and polygonal shapes.
  • the superhard material can comprise a boron nitride, such as cubic boron nitride (CBN) , a diamond material such as polycrystalline diamond (PCD) or a suit- able oxide or nitride ceramic such as alumina or silicon nitride or mixes thereof.
  • CBN, PCD or Ceramic material can have additions of other materials, such as carbides, nitrides, carbonitrides, oxides, and/or borides of metals chosen from groups IVa to Via of the periodic table and other elements as known in the art such as Al.
  • a CBN composite comprises 40-80, most preferably 55-70, vol-% CBN with an average grain size of less than 30 ⁇ m, preferably less than 5 ⁇ m, more preferably 0.1-4 ⁇ m essentially in one or more cBN grain size fractions for example bimodal.
  • the PCBN material also contains smaller amounts (typically ⁇ 10 wt% each) of other elements, e.g. Co, Ni, Al, W often as compounds such as WC, AlN and Al 2 O 3 .
  • the PCBN material according to the invention contains more than 60 wt-% CBN, preferably more than 80-wt% CBN, with at least 2 wt% aluminium compound and can include another component, generally Co-based. This material is particularly useful for the machining of cast iron.
  • Figures 3A-G are illustrative of three alternative cutting tip configurations hereby denominated as symmetric at least in the top surface plane: 20a, 20b and 20c. These cutting tip configurations differ with respect to the amount of superhard material contained therein. As illustrated in said figures, a cutting tip is configured such that the superhard material is a relatively minor component thereof 20a or a cutting tip can be configured such that it is formed entirely from superhard cutting material 20c.
  • the superhard material 16 is continuous from a top surface of the tips (not visible in Figs 3A, 3B and 3C) to an opposing bottom surface of the tips illustratively shown in Fig 3D.
  • the superhard material 16 is discontinuous from a top surface of the tips (not visible in Fig 3A, 3B and 3C) to an opposing bottom surface of the tips and interposed with at least one layer of a material that differs from the superhard material on the top and bottom surface illustratively shown in Fig 3E and 3F.
