Abstract

Embodiments of stone cutting apparatus may include at least one sheave, which is coupled to a stone cutting belt to drivingly engage the stone cutting belt. Belt may include an endless cable, numerous abrasive segments disposed along the length of the cable, and a flexible belt body encapsulating the cable, and extending into the abrasive segments and between the abrasive segments. The abrasive segments may include a diamond top portion, a metal bottom portion, a first side, a second side, a first end and a second end. At least one bore in each abrasive segment, extending from the first and through the second end, is adapted to house the cable. The perimeter of the bore may be formed by the top diamond portion, the metal bottom portion and the interface between the diamond and metal portions of the abrasive segment. In another embodiment, each abrasive segment may further include a cutting portion and a mounting portion. The cutting portion faces a stone to be cut, and may project above the main belt body. The mounting portion is located opposite the cutting portion, and has a top, a middle, and a tongue. The tongue is made of metal and generally V-shaped. The tongue is adapted to extend into an outer circumference of the sheave, thus allowing the sheave to drivingly engage the abrasive segment. Methods of manufacturing a stone cutting belt are also disclosed.
