Definitions

  • the thickness of the two layers may vary in conventional manner depending upon the application of the products. However, it is preferred to employ the two dispersions in a ratio such that the first, diamond-containing layer will be from 0.25 to 0.8 mm. in thickness for cutting inserts. It is also preferred that the layer be flat.
  • the non-diamond containing admixture was employed to substantially fill the depression of a mold. On top of that admixture was placed a thin layer of the first, diamond-containing admixture. Then the mold contents were compacted under a conventional pressure to produce an integral bi-layer composite.
  • sample composites of this process were each in the form (identical to that of the mold depression) of a 1/2 inch square, positive insert having a 1/32 inch nose radius and a 5° relief.
  • Two of these samples (denominated test samples A and A 1 ) were comparatively tested against similarly shaped tungsten carbide inserts, and commercial polycrystalline diamond inserts.
  • the tests involved turning a 390 aluminum alloy using a depth of cut of 0.010 inches and a feed rate of 0.002 in revoluation without using coolant until the insert showed a wear of 0.015 inch (i.e., the end of its effective tool life). The results of the tests are depicted in
  • FIG. 2 as a function of cutting speed.
  • the samples (A and A 1 ) of the present invention permit significantly higher speeds of use for a given tool life time and significantly lengthened life times for a given speed of use. This indicated they also possess superior physical hardness and/or stability.
