Abstract: We proposed a microprocessing method using a magnetic compound fluid
for the inner surface of a tube made of a material that is difficult to cut,
and clarified the processing characteristics and magnetic field distribution of
the tool. The tool inserted into the tube comprises a stack of ring-shaped
permanent magnets with spacers between them. There is an almost proportional
relationship between the amount of material removed and the processing time,
and the processed surface acquires a mirror finish. Moreover, for tools with
shorter permanent magnets, the circularity is improved by processing.
