THE POLYCRYSTALLINE DIAMOND (PCD) PROCESS

PRECORP’s PCD process is the method for making unique shaped diamond edges which enables the creation of innovative diamond tooling solutions for common and special problems.

PCDprocess-step1-aeroSTEP 1
A carbide blank is slotted and polycrystalline diamond (PCD) powder is inserted.

PCDprocess-step2-aeroSTEP 2
The carbide blank is inserted into one of Precorp’s high-pressure, high-temperature presses and subjected to 2,700 degrees F and 876,000 PSI. In this process the diamond powder is compressed and the diamond crystals are bonded to each other and to the carbide blank.

The PCD nib is then brazed to a solid carbide shank. The braze is located sufficiently away from the tip of the tool to avoid any potential thermal damage. This allows the use of a high-temperature, high-strength braze joint between the nib and the carbide shank.

The drill geometry is ground to produce the finished PCD tool. This patented process allows for many tool geometries that are impractical and/or impossible using conventional PCD insert processes.
