MAGNETIC POLISHING METHOD AND POLISHING SLURRY

摘要

PROBLEM TO BE SOLVED: To provide a magnetic polishing method capable of precisely polishing an inner surface of a resin pipe, and the like, and a polishing slurry.SOLUTION: A magnetic polishing method includes polishing an inner surface of a resin pipe 1 with a polishing slurry 2 while relatively moving the resin pipe 1 and the polishing slurry 2 introduced into the resin pipe 1. The polishing slurry 2 is structured so as to have magnetic particles having an average particle size of 100 μm or more, polishing particles having an average particle size smaller than the average particle size of the magnetic particles, and a slurry medium making the magnetic particles and the polishing particles into a slurry state.
