AI Technical Summary
In the existing technology, polycrystalline diamond drill bits have low processing efficiency, produce a lot of debris, and suffer from severe tool wear and short service life when drilling hard and brittle materials such as silicon carbide and ceramics.
Design a drilling tool, including a tool holder and a tool head, with a first channel set in the center of the tool head to avoid residual core of the material to be processed, reduce grinding volume and chip amount, and an abrasive layer set on the surface of the tool head to improve grinding efficiency and reduce friction.
It improves processing efficiency, reduces chip volume, reduces tool wear, and extends tool life, making it particularly suitable for machining large-diameter and long holes.
