METHOD AND APPARATUS FOR ELECTRICALLY CONTROLLING LUBRICATION IN LUBRICATED PLASTIC-WORKING OF METALLIC MATERIAL

摘要

A method for electrically controlling lubrication in lubricated plastic-working of a metallic material, and an apparatus for carrying out the method, which comprises incorporating a working tool and/or a work into a DC circuit to form a pole in face-to-face relation with an opposite pole, and conducting current between the two opposing poles to produce an electric field in an emulsion type lubricant oil prevailing therebetween, causing the lubricant oil to be electrically pulled toward the working tool and/or the work, thereby increasing the adherence of the lubricant oil to the working tool and/or the work.
