Diamond wire is a cutting tool that is commonly used in the manufacturing industry for cutting crystalline materials such as silicon, germanium, and quartz. The wire is made of a steel core that is coated with diamond grit, providing a highly abrasive and durable cutting surface. As the wire is pulled through the crystalline material, the diamond particles on the wire create fine chips, resulting in a precise and clean cut. Diamond wire cutting technology has many advantages over traditional cutting techniques, including reduced kerf (width of cut), increased cutting speed, and improved surface finish. It is used in a wide range of applications, including the production of solar cells, semiconductors, and high-precision components for the electronics industry.
