Studies are made of the cutting of ultrahard materials (refractories, concretes, ceramics, single crystals) and relatively “soft” refractories and natural stones by using disks with two types of diamond-bearing layer: a layer with a cluster design (fine aggregates with a high-density diamond distribution) and a layer with a fragmentary design (coarse aggregates with a significantly less dense diamond distribution). Use of these types of diamond-bearing layer increases both cutting speed and tool life compared to the traditional uniform distribution of diamonds. The cluster design is effective for cutting ultrahard materials, while the fragmentary design is best suited for cutting softer materials.
