Abrasive cutting tool and cutting method

摘要

A tool for removing material from a surface includes a body defining a longitudinal bore and an opening connecting an outer surface of the body to the longitudinal bore. A cutting element comprising a cutting surface is dimensioned to be at least partially received by the opening. The cutting surface is configured to translate from a first position to a second position in response to a centrifugal force. In the second position the cutting surface is extended outwardly through the opening, beyond the outer surface of the body. In one example, the tool may be used to remove material, such as oxidation, from the inner walls of a cylindrical article selected from a pipe and a tube.

1. An abrasive cutting tool, comprising:
a body defining a substantially cylindrical outer surface, a longitudinal bore having a longitudinal axis, and an opening in the substantially cylindrical outer surface connecting the outer surface of the body to the longitudinal bore; and a cutting element comprising a cutting surface, wherein the cutting element is at least partially received within the opening and the cutting element linearly slides within the opening in the body along an axis substantially perpendicular to the longitudinal axis from a first position to a second position in response to a centrifugal force, wherein in the first position the cutting surface of the cutting element is retained in the body and does not extend beyond the outer surface, and wherein in the second position the cutting surface of the cutting element extends outwardly through the opening beyond the outer surface of the body.
