Характеристики
PDC cutters leached size 1308 13013 1608 1616 1916 for water well drilling
Forming PDC into useful shapes for cutters involves placing diamond grit, together with its substrate, in a pressure vessel and then sintering at high heat and pressure. PDC cutters cannot be allowed to exceed temperatures of 1,382°F [750°C]. Excessive heat produces rapid wear, because differential thermal expansion between binder and diamond tends to break the intergrown diamond grit crystals in the diamond table. Bond strengths between the diamond table and tungsten carbide substrate are also jeopardized by differential thermal expansion. Geometric considerations include bit shape or profile, which is predicated based on:
* PDC Cutter geometry.
* PDC Cutter placements.
* PDC Cutter density.
* PDC Hydraulic requirements.
* PDC The abrasiveness and strength of the formations to be drilled and well geometry.

PDC Application
PDC cutter is widely used in oil and ore field, for drilling oil well or iron, copper, and other ore mining.
