With the vigorous development of the automobile manufacturing industry, how to improve manufacturing efficiency and effectively reduce manufacturing costs while ensuring automobile quality has become the focus of increasing attention. Research shows that replacing traditional cutting tools with more advanced cutting tools is seen as an effective way to reduce costs and increase efficiency in automobile manufacturing.

In the process of processing automobile parts, the cost of hole processing and milling accounts for most of the processing cost of the entire parts. The cost of hole processing remains high. First, it is because some holes are difficult to process. Second, the traditional hole processing cost control method needs to be improved. Traditional hole machining cost control is achieved through repeated tool grinding. However, there are three major problems in grinding: first, it is difficult to position during grinding, and the shape of the tool tip is easy to deviate; second, repeated grinding will cause the diameter of the drill bit to become smaller; third, each re-grinding will shorten the overall length of the drill bit.
