Special tools for composite materials

In the field of aviation manufacturing, the requirements of aircraft parts materials should be safe, reliable, and as lightweight as possible. Lightweight materials are the best choice, but the machining process is difficult and there is requirement strictly for the cutting tool. Normal carbide tools are prone to problems such as rapid wear and residual burrs during processing, which cannot meet the requirements of high-efficiency and high-precision processing. Due to the high hardness and high wear resistance of the material itself, PCD tools can well meet the processing requirements of lightweight composite materials, and its popularization and application will become an inevitable trend in the development of processing technology in this field.
