The Manufacturing Process of PCD Tools
Jun 05 , 2021

The manufacturing process of PCD tools mainly includes two stages:

① Manufacturing of PCD composite sheet:

PCD composite sheet is made of natural or synthetic diamond powder and binder (including cobalt, nickel and other metals) in a certain proportion at high temperature (1000~2000C), sintered under high pressure (50,000 to 100,000 atmospheres). During the sintering process, due to the addition of the bonding agent, a bonding bridge with TiC, SiC, Fe, Co, Ni, etc. as the main components is formed between the diamond crystals, and the diamond crystals are embedded in the framework of the bonding bridge in the form of covalent bonds. Usually the composite sheet is made into a disc with a fixed diameter and thickness, and the sintered composite sheet needs to be ground and polished and other corresponding physical and chemical treatments.

②Processing of PCD blades: The processing of PCD blades mainly includes the steps of cutting the composite sheet, welding the blade, and sharpening the blade.


The appearance of PCD has replaced natural single crystal which called diamond in many aspects. Compared with natural diamond, PCD is cheaper, and sharpening is far more convenient than natural diamond, so its application and promotion are particularly rapid by now. Transgrindtools is dedicated to providing suitable PCD removal tooling to support you go thought you job successfully and effectively.
