[0002] During the machining of new energy bearings, it is necessary to drill the assembly holes for these bearings. D62H8 hole walls require a roughness of Rz10-20, and D90S6 high-precision holes. Traditional PCD reamers struggle to eliminate machine runout, resulting in excessive roundness in the reamed holes and difficulty in stable machining. Therefore, we developed an adjustable PCD precision reamer to address this issue. Utility Model Content

The tool holder can be adjusted by setting the flange adjusting screw and the flange gasket, which can effectively offset the adjustment of the equipment spindle and enable the tool to be clamped to within 0.002 of the equipment runout, thus meeting the needs of high-precision precision reaming of inner holes;

[0014] In the present invention, the PCD adjustable fine reamer is used. In addition, in order to meet the roughness of Rz10-20, the traditional tool needs to add a breaking blade boring tool, which prolongs the processing time. In this paper, the connecting part and the breaking blade are installed in the installation groove of the tool holder. By combining the PCD reamer with the breaking blade, the fine reaming and the hole wall roughness can be met at the same time, thereby achieving stable and high-precision processing.
