The connecting layer 12 is a high-strength adhesive material, which is used above the first anti-oxidation layer 11 and below the first thermal insulation layer 13 to reinforce the strength of the two layers.

[0026] A first heat insulating layer 13 is arranged outside the connecting layer 12, and the inner wall of the first heat insulating layer 13 is fixedly connected to the outer surface of the connecting layer 12. The first heat insulating layer 13 is a material that can block heat flow transfer, also known as a thermal insulation material, to reduce the impact of high temperature on the reamer block 5.

[0027] A first wear-resistant layer 14 is arranged on the outer side of the first heat-insulating layer 13. The inner wall of the first wear-resistant layer 14 is fixedly connected to the outer surface of the first heat-insulating layer 13. The first wear-resistant layer 14 is prepared by coating a thin layer of refractory metal or non-metallic compound with good wear resistance on the surface of a cemented carbide or high-speed steel substrate with good strength and toughness by using a vapor deposition method, thereby extending the service life of the reamer block 5.

[0028] Four thread milling blocks 8 are fixedly connected to the outer surface of the thread milling cutter 6, four breaking edges 9 are provided on the upper surface of the thread milling cutter 6, a storage bin 10 is provided on the upper surface of the thread milling cutter 6, a second anti-oxidation layer 15 is provided on the outer side of the thread milling block 8, and the inner wall of the second anti-oxidation layer 15 is fixedly connected to the outer surface of the thread milling block 8.

A large amount of debris will be generated in the processing process, and most of the debris will come out from the top of the tool, but a small amount of debris will remain inside the hole.

The thread milling block 8 is used to control the size of the tapped outer ring, and the cooperation of the reamer column 4 and the reamer block 5 can ensure that the inner wall of the hole is smooth, so that the PCB composite processing tool can tap a threaded hole at one time without replacing the tool back and forth. The composite processing tool has the advantage of high-efficiency tapping threaded holes.
