Method of reducing wear in lubricated metal cutting operation

A method of reducing wear in a lubricated metal cutting operation, comprising:

• (a) providing an electrical cutting cell having an anodic conductive cutting tool and a cathodic conductive work-piece connected to a DC current supply, and a lubricant containing platable wear reducing agents and arranged to bathe the contacting interface between the cutting tool and work-piece to function as an electrolyte;
• (b) controlling the electrical current flow through the contacting interface to be in the range of 25-500 milli-amps;
• and (c) moving the cutting tool into and along cutting contact with the work-piece while current flows there-between to electro-chemically deposit the wear reducing agents on at least the contacting interface for reducing cutting tool wear and improving the ease of mass removal, wherein said electrolyte is comprised of a water and oil emulsion, the oil containing one or more aware reducing agents selected from the group consisting of zinc, calcium, sodium, phosphorus and sulfur.
