Use of Diamond Wire Saw
Diamond wire cutting (DWC) is the process of using wire of various diameters and lengths, impregnated with diamond dust of various sizes to cut through materials. Because of the hardness of diamonds, this cutting technique can cut through almost any material that is softer than the diamond abrasive. DWC is also practical and less expensive than some other cutting techniques, for example, thin diamond wire cost around 10-20 cents per foot ($0.7/m) in 2005 for 140 to 500 micrometer diameter wire, to manufacture and sells around $1.25 a foot ($4.10/m) or more, compared to solid diamond impregnated blade cutters costing thousands of dollars. Thus a 1,000 foot (300 m) spool of diamond wire costs around $200 to manufacture and sells for around $1,250. Selling cost may vary because of wire grade and demand. Other diamond wire cutting can use shaped diamond rings threaded through cables. These larger cables are used to cut concrete and other large projects.
