Cold pressing process of diamond segments

What is cold processing ? some manufacturers designed the cold processing workshop as a conditioning room , but some are not take seriously , so most of cold-processing process are being done under normal condition , specific complete way is to put the agitation of the powder (containing diamond particles and matrix materials), through the way of pressure, pressed powder become block, through such way of cold pressing diamond and matrix can be preliminary unifies in together, forming the shape of the cutting tools, that’s why to say the cold press is an a very critical step in the process of

The instruction of PCD gringding wheel

Most of the CBN grinding wheel substrate is made of metal, and when the CBN grinding wheel is grinding, most of the heat energy will be transmitted to the direction of the grinding wheel. Therefore, in the grinding process, heat energy will be continuously transferred to the grinding wheel. The metal matrix then begins to expand as heat accumulates.
