AI Technical Summary

Technical Problem

The existing drill bits are mainly used for rough drilling, which is difficult to achieve high precision, and requires additional tools for finishing, resulting in high production costs and low efficiency.

Method used

A drilling and reaming integrated milling cutter is designed, combining cutting edge and tool holder structure, including the main cutting edge, rough processing circumferential cutting edge of drilling hole, axial end cutting edge of fine reaming hole and chip drainage groove, and the surface of the tool holder body It is equipped with an inline groove and a trapezoidal inclined surface to enhance installation smoothness and friction and prevent rotation and slipping.

Benefits of technology

The precision molding of the holes is achieved in one processing, saving the cost of purchasing multiple tools, improving production efficiency, and preventing the milling cutter from slipping through enhanced friction, ensuring the use effect.
