Status and prospects of brazed diamond tools
04 Jun 2025
Abstract：In this paper，the current research status of brazed diamond tools at home and abroad were introduced from four aspects，the brazing technology, brazing alloy, brazed diamond tools and automatic production. The future perspectives in brazed diamond tools were also put forward. The influences of brazing temperature, holding time and alloy composition on the properties of brazing diamond were discussed in detail. Appropriate brazing temperature and holding time could ensure the sufficient reaction at the diamond/brazing material interface, enhance the interface bonding strength, and achieve good brazing joint quality. The appropriate addition of elements or compounds in the brazing alloy could regulate the performance of the brazing alloy, reduce the graphitization of diamond and the thermal damage of diamond. Achievements in the conventional brazed diamond tools, the diamond tools with orderly arrayed abrasive, the brazed fine grain diamond tools were summarized. Compared with electroplated diamond tools and sintered diamond tools，the brazed diamond tools have the unparalleled advantages. The orderly arrangement of diamonds could improve the cutting efficiency and tool lifespan, and improve the surface quality of the workpiece. The research on the urgent issues in fine-grained brazed diamond tools that the uneven distribution of the thickness of the solder layer and the uniformity of the abrasive grains were also summarized.
