<p>A metal wire with self-construction capability used in free abrasive cutting, the axis of the metal wire being a straight or approximately straight line, the cross-section thereof being a circle or approximate circle, and a plurality of wear-resistant areas having higher hardness than other areas being regularly arranged axially on the surface of the metal wire; and a metal wire manufacturing device and method. When being used in multi-wire free abrasive cutting, the metal wire will gradually self-construct surface depressions or protrusions in a cutting feed direction following the abrasion to the metal wire caused by the abrasives, such that the resultant surface stereoscopic structure enhances abrasives carrying capacity, thus improving the ability to maintain a consistent good product rate from the cutting starting end to the cutting tail end.</p> |
