PURPOSE: A recycling method is provided to regulate recycling systems efficiently by precise adjustment of the respective feed rates of abrasive grain waste liquid, fine grain mixed liquid, fresh cutting liquid or fresh abrasive grain. CONSTITUTION: A recycling method comprises the steps of directing an abrasive grain waste liquid to a first separator; directing the recycled abrasive grain from the first separator to a recovered abrasive grain tank; directing the fine abrasive grain mixed liquid from the first separator to a separated liquid tank; adding fresh cutting liquid to the fine abrasive grain mixed liquid in the separated liquid tank and directing the resulting liquid to a second separator and subjecting it to separation into waste abrasive grain and recovered cutting liquid; directing the recovered cutting liquid from the second separator to a recovered cutting liquid tank and directing the recovered cutting liquid from the recovered cutting liquid tank to the recovered abrasive grain tank; adding fresh abrasive grain and cutting liquid for dilution to the recovered cutting liquid and to the recycled abrasive grain; and feeding the recycled abrasive grain mixed cutting liquid to an abrasive grain supply tank.
