发明名称 FUNCTIONALLY LEACHED PCD CUTTER
摘要 A cutting table includes a cutting surface, an opposing surface, a cutting table outer wall, and one or more slots. The cutting table outer wall extends from the circumference of the opposing surface to the circumference of the cutting surface. The slots extend from a portion of the cutting surface to a portion of the cutting table outer wall. The cutting table is leached to form a thermally stable cutting table. One or more slots are positioned in parallel with at least another slot in some embodiments. In some embodiments, the slots are positioned circumferentially around the cutting surface. In some embodiments, at least one slot is backfilled with a backfilling material to increase heat transfer or impact resistance. In some embodiments, the cutting table is coupled to a substrate to form a cutter. The slots are formed either after or during the formation of the cutting table.
