Diamond cutting tools are usually manufactured using powder metallurgy. The traditional sintering process uses a simple hot-pressing method. During the pressing step of the hot-pressing process, collisions occur between the pressing parts and the matrix powder, causing the powder to splash or shift, which affects the quality of the final diamond cutting tool.
