Abstract: Wheel hub is an essential key part of the automobile, wheel hub tire bolt ring hole not only high precision requirements, and has a large number, so the processing method and tool selection is directly related to the processing accuracy and efficiency of the wheel hub ring hole. This paper analyzes and optimizes the machining technology of a wheel ring hole by using the method of work step combination, and designs and produces the composite boring cutter independently. On the basis of ensuring the precision of the wheel hub ring hole, the machining efficiency of the wheel hub is effectively improved and the cost is reduced.

Key words: Processing process method; Wheel hub ring hole; Processing accuracy; Processing efficiency; Composite boring cutter
