Abstract

In response to the problem of low efficiency in milling/grinding, the new collar eye grinding shoes can greatly improve operational efficiency, shorten the adjustment well project period, and achieve the goal of cost reduction and efficiency improvement. The movement trajectory of the tool blade wing of the lead eye shoe grinding tool affects the tool design results. Therefore, research has been conducted on the movement trajectory of the tool blade wing. The study shows that when the size of the lead eye shoe grinding tool's supporting wing is constant, the maximum size of the lead eye shoe grinding tool blade wing is related to the scale of the casing to be processed, and is not related to the scale of the casing on the previous level.
