Compliant grinding tool can solve the problem of precision processing of complex structural components. However, owing to the weak thermal conductivity of the workpiece and the weak thermal stability of the tool base material, the build‑up of grinding heat restricts the life and performance of the grinding tool. To alleviate this issue, an augmented thermal transport structure, inspired by the fan blade, is incorporated into the design of a ball‑end grinding tool to augment its thermal transport capabilities. The grinding tool is fabricated based on multi‑jet fusion (MJF) technology. The tool's thermal transport phenomenon was examined through numerical simulation, considering the impact of rotation direction, rotational speed, and cold air velocity. The grinding performance of the designed tool was comparatively investigated with that of the traditional structure tool through the grinding experiments. The results show that the internal blade structure effectively introduces high-momentum fluid into the internal chamber of the tool, increases the pressure in the internal chamber of the grinding tool, and augments the thermal transport efficiency of the grinding tool with a peak temperature reduction of up to 18.29 %. In continuous grinding experiments, Flexible material adhesion owing to heat build‑up was effectively reduced, thus extending tool life by more than 40%.
