Title:
SUPER-ABRASIVE GRAIN FIXED TYPE WIRE SAW, AND METHOD OF MANUFACTURING SUPER-ABRASIVE GRAIN FIXED TYPE WIRE SAW
Document Type and Number:
WIPO Patent Application WO/2011/055692
Kind Code:
A1
Abstract:
A problem with the resin bonding method is that the service life is short. Problems with the electrodeposition method are that productivity is unsatisfactory and cost is high. Problems with the brazing method are that no high carbon steel can be used, resulting in cost disadvantages, and that subsequent to brazing, internal stress is generated in super-abrasive grains, resulting in super-abrasive grains being susceptible to cracking or chipping. Provided is a super-abrasive grain fixed type wire saw which is capable of solving all these problems, which has a long service life and high productivity, and which excels in cutting capability. 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.
