  • Publication number: 20080038514
    Abstract: A graphite block cut into slabs by a sawing device comprising a plurality of generally parallel, spaced-apart blades with each of the blades having a plurality of cutting segments mounted thereon, each of the cutting segments comprising a continuous phase impregnated with a superabrasive material selected from one of natural diamond, synthetic diamond, cubic boron nitride, and combinations thereof; wherein each of the granite slabs as cut from the block has a surface roughness Ra of less than 500 & micro-in, and with thickness variation of 2 mm or less from a nominal slab target.
    Type: Application

  • Patent number: 7082939
    Abstract: A horizontal frame saw is equipped with a plurality of generally parallel, spaced-apart blades for cutting granite. Each of the blades has a cutting edge with diamond cutting segments mounted thereon for engaging the granite with a swinging motion for cutting of the granite, wherein the segments have optimized/controlled segment variables for uniform wearing of the segments along each blade during cutting of granite. Segment variables include one or more of: spacing of segments along the length of the blade; diamond concentration in each segment; diamond grade (as measured by compressive fracture strength) in each segment; segment composition (bond, secondary abrasives); or segment dimensions.
