First, the small kerf loss due to the fine wire used allows a high yield of product and second, cutting though multiple layers does not cause a wiping of one layer into the next, thus saving added cleanup or processing steps. X Sectioned Fuel Injector Cutting with a diamond wire saw generates very little heat because of the size of the diamonds doing the work and the controlled cutting force that is applied. Often, tests have been made showing a temperature rise of less than 10 degree. During a cut. This feature is quite useful.
Heat causes smearing when cutting metals which leads to burrs.
Diamond wire cutting of metals, even small metal tubing such as medical or instrument capillary tubing, will not generate burrs or smearing. Cutting bundled metal wires results in a clean cut, clearly showing each individual wire. Heat causes surface smearing of single crystal semiconductors, rearranging atoms which causes much secondary processing. Cutting with diamond wire greatly reduces this smearing, thus saving secondary processing. When cutting explosives or solid rocket fuel, generating heat is a serious problem.
