Ultra-precision polishing combined with UV irradiation was applied to the truing of a diamond grit-arranged block to develop a new diamond wheel truing method (UV-truing). By UV-truing experiments, the variation in the top position of diamond abrasive grains could be minimized within 10μm. The formation of a sharpened edge around an abrasive flat area and well-polished abrasive flat areas with 6.8 nmRa were simultaneously achieved. These diamond grit-arranged blocks were applied as a new type of milling tool. The milling of aluminum alloy A5052 indicated an excellent cutting surface with 15 nmRa (estimated by Zygo).
