Magnetic abrasive finishing is very interesting finishing method, but this has a weak point of low grindability. Electrolytic-magnetic abrasive finishing is thought as one of the potential method to improve this weak point. This study aims at developing the new abrasive for electrolyticmagnetic finishing and investigating the grindability of this abrasive. The ferrite-Al2O3 abrasive which was made by sintering has high grindability in comparison with sintered ferrite abrasives or soft ferrite raw powders. Ferrite-base abrasives will become a very useful in the electrolytic-magnetic abrasive finishing.
