[0002] Silicon wafers used in large quantities in the photovoltaic industry are mainly obtained by cutting silicon ingots. In the field of crystalline silicon cutting, major manufacturers all use multi-wire cutting technology. The mechanism is that the machine guide wheel drives the steel wire during high-speed operation, so that the steel wire delivers the mortar mixed with cutting fluid and silicon carbide micropowder to the cutting area. During the high-speed operation of the steel wire, the cutting process is completed through continuous friction with the workpiece pressed on the wire mesh.
