  • Publication number: 20130032129
    Abstract: The super-abrasive grain fixed type wire saw is equipped with two layers consisting of a brazing material layer (13) and a metal plating layer (16), the aforementioned brazing material layer (13) serving to temporarily fix super-abrasive grains (14), and the aforementioned metal plating layer (16) serving to hold the super-abrasive grains (14). The thickness of the brazing material layer (13) is 10% or less of the average grain diameter of the super-abrasive grains (14). The brazing material layer (13) is formed on the surface of a wire (10) in advance. The super-abrasive grains (14) are dispersed and adhered in a single layer onto the brazing material layer (13). Subsequently, the surface of the brazing material layer (13) is melted and solidified, resulting in a super-abrasive-grains-temporarily-adhered wire (12) such that super-abrasive grains (14) are joined to the adhesion surface of the brazing material layer (13). Thereafter, the super-abrasive-grains-temporarily-adhered wire (12) is metal-plated.
