Polycrystalline diamond PCD tools are mainly used for machining wear-resistant non-ferrous metals and their alloys and non-metallic materials. Compared with the carbide tools,

they can maintain sharp edges and cutting efficiency during long cutting processes. The tool life is much higher than the carbide tools. In the field of PCD tool applications, turning

accounted for 37.6%, boring accounted for 27.1% and milling accounted for 1.2%.

When processing aluminum alloys with a high silicon content, all tools except PCD tools produce severe wear in a short period of time and cannot continue cutting.
