The invention relates to a small-size sapphire ball cover grinding tool based on a controlled structure CVD diamond film. The small-size sapphire ball cover grinding tool is mainly composed of a tool substrate, a controlled structure CVD diamond film coating insert and an elastic supporting body; and the CVD diamond film is deposed on an insert substrate, diamond grains having the grinding effect are evenly and compactly distributed on the overall surface of the insert, and the grinding efficiency is high. The controlled structure can be achieved by controlling the preparation parameters; and the surface roughness of the prepared insert is lower; an elastic supporting body is arranged between the insert and the tool substrate, and the buffer effect is achieved in the grinding effect. The small-size sapphire ball cover grinding tool is high inn machining quality, free of stress and scratches, simple in structure and convenient to manufacture.
