More Information
Summary:A method of recycling and purifying water-soluble cutting agents is disclosed. The used water-soluble cutting agent is recycled by filtering through an oil-water separating filter consisting of a porous sheet and an oil-water separating layer composed essentially of a water-insoluble and water absorbable gel layer, which is formed on a surface portion of the porous sheet and is adapted to be contacted with the cutting agent and/or surface portions of the porous sheet serving as flow path.
