Abstract
In an embodiment, a cutter assembly for use on a tunnel boring machine may include a cutter ring extending circumferentially about a central axis. The cutter ring may include a radially inner surface and a radially outer surface. The cutter assembly may also include superabrasive cutting elements distributed circumferentially about the axis. Each of the superabrasive cutting elements may be attached to the cutter ring and may include a polycrystalline diamond ('PCD') body having a working surface. At least a number of the cutting elements may extend beyond the outer surface of the cutter ring.
