The biggest volume of diamond saws is used in cutting stone and refractory materials. Abrasive wires and saws are also used in the electronics and solar industry to cut silicon and quartz crystals into wafers. In Multi-Wire-Slicing, a wire is led by several coils to form several wire lines, which cut simultaneously [KLOC09, p. 386]. The wire can either contain grits or work within a grit containing slurry (Fig. 4.9 left).

4.6.1 Wires with. Bonded Grits
Wires with bonded grits consist of a core coated with abrasive grits, mostly diamond. The diamonds can be bonded through resin bonds or by electroplating [CHIB03, KLOC09, p. 385]. Chiba et al. [CHIB03] presented a new high-speed electroplating process to manufacture the wire saws faster and cheaper.
