Abstract
Abstract An electroplate honing technique that utilizes mechanical abrading or honing to clean the metallic surface of a workpiece, then with the tool acting as an electrode, utilizes an electroplate honing cycle to plate or deposit metal on the surface of the workpiece, then terminating the flow of current and utilizing a honing cycle to generate the surface finish desired by mechanical abrasion.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
39 words
A method of plating and honing a metallic work surface with a honing tool having an electrically conductive tool body and at least one abrasive member supported by and adjustable outwardly from said tool body, comprising the steps of:
Claim 2
Dependent Claim
14 words
maintaining said electrically conductive tool body in a spaced relationship to the work surface;
Claim 3
Dependent Claim
15 words
maintaining said electrically conductive tool body portion in a spaced relationship to the work surface;
Claim 4
Dependent Claim
15 words
flowing a plating solution between the work surface and the electrically conductive tool body portion;
Claim 5
Dependent Claim
19 words
advancing the abrasive member into abrasive engagement with the work surface to remove metal mechanically from the work surface;
Claim 6
Dependent Claim
14 words
flowing a plating electrolyte between the work surface and the electrically conductive tool body;
Claim 7
Dependent Claim
8 words
honing the work surface to clean said surface;
Claim 8
Dependent Claim
24 words
initiating current flow with the workpiece negative potential and the tool positive potential, so that metal is plated onto the surface of the workpiece;
Claim 9
Dependent Claim
8 words
honing the work surface to clean said surface;
Claim 10
Dependent Claim
26 words
initiating the flow of direct electric current from said work surface to said electrically conductive tool body through said plating electrolyte to plate said work surface;
Claim 11
Dependent Claim
30 words
keeping the abrasive member rubbing on the work surface during plating to keep the surface clean, refine the grain structure of the plated material, and correct errors in geometric shape;
Claim 12
Dependent Claim
7 words
terminating the supply of direct current; and,
Claim 13
Dependent Claim
14 words
applying low-abrasive pressure against said work surface as said work surface is being plated;
Claim 14
Dependent Claim
7 words
terminating the supply of direct electric current;
Claim 15
Dependent Claim
27 words
advancing the abrasive member into increasing pressure with the work surface to remove the metal mechanically form said work surface and generate a controlled cut surface finish.
Claim 16
Dependent Claim
9 words
applying a high-abrasive pressure against said work surface; and
Claim 17
Dependent Claim
9 words
retracting the abrasive member after a predetermined time interval.
