PROBLEM TO BE SOLVED: To provide a wet honing treatment apparatus which can perform continuous treatment while consistently maintaining the concentration of a granular abrasive in a polishing liquid with the least possible space and driving power.;SOLUTION: A polishing liquid tank of the wet honing treatment apparatus is provided with a working section A and a working section B. The working section B exists above the working section A and both the working sections are divided by a partition section having an opening in the central part. In the working section A, spiral flow is generated by the polishing liquid flowing therein, by which the granular abrasive is classified and the sedimentary separation of the granular abrasive in the working section B from the solvent is promoted.;COPYRIGHT: (C)2005,JPO&NCIPI
