Application of PCD Tools in Titanium Alloy Processing

Titanium alloys are widely used in aircraft, ships, armor and missiles due to their high strength ratio, high corrosion resistance and good high temperature performance. However, these characteristics of titanium alloys also bring challenges in processing, such as high temperature chemical reactivity, low thermal conductivity and low elastic modulus, making titanium alloy one of the difficult materials to process. Traditional tool materials, such as high-speed steel and cemented carbide, often face severe wear and low processing efficiency when processing titanium alloys. Therefore, it is particularly important to find a tool material that is more suitable for titanium alloy processing.

PCD (polycrystalline diamond) tools are one of the ideal choices for processing titanium alloys due to their excellent hardness and wear resistance, high thermal stability and chemical stability, and excellent thermal conductivity. The hardness of PCD tools is much higher than that of cemented carbide and high-speed steel. They can resist the cutting force and cutting heat generated during the processing of titanium alloys, reduce tool wear, and thus improve processing efficiency and processing quality.
