The sharp burrs produced by plastic deformation during machining of the precision
components deteriorates the precision and performance of a machine. Thus, effective removal of the
burrs may improve productivity and performance of the machinery. This study was conducted based
on the experiment to remove fine burrs produced during machining process using the magnetic
abrasive finishing method. The magnetic abrasive finishing using the abrasive feature of an abrasive
and the magnetic nature of iron is an abrasive method to brush the burrs with iron powder that has a
cohesive power due to the line of induction. The purpose of this study is to remove the burrs at
intersecting holes which are difficult to access with tools, using the magnetic abrasive finishing
method. Special tool is designed for deburring micro burr at intersecting holes. To find the proper
deburring condition, gap distance, rotational speed of inductor, components of powder and effect of
coolant are analyzed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
