Choose high-quality natural diamond crystals with minimal impurities. Evaluate the crystal’s orientation and hardness to ensure suitability for the intended wire diameter.
The diamond is cut and shaped into a cylindrical or conical form using lasers or precision grinders.
The diamond is mounted into a stainless-steel case (regularly 25mm, 28mm or 30mm diameter cylinder. Space between the diamond and steel case will be filled with high-strength sintering powder.
Advanced designed laser drill machine can make the hole in the center of a die. The hole size and profile are highly finished.
The die’s bore is polished to a mirror-like finish using diamond paste or other abrasive materials.
Microscopic and dimensional inspections(2D&3D) are conducted to confirm precision and surface finish.
