Abstract

Abstract The segmented flexible hone comprises spirally wound high pressure tubing for conducting a lubricant therethrough with multiple bristled segments for contacting the inner surfaces of tubular holes so that contaminants and metal may be removed from the inner surfaces of the tubular holes. The bristled segments comprise compliant nylon bristles having enlarged abrasive globules attached to the outer end of the bristles in a non-flaking and a non-chipping manner. The bristled segments are separated by intervals along the high pressure tubing wherein no bristles are disposed but wherein the tubing has holes so that a lubricant mist may exit at high pressures and in a mist therefrom. The segmented flexible hone may be attached to a high pressure lubricant source and a mechanism for rotating the hone such that the ends of the bristles contact the inner surfaces of the members to be honed while a mist of lubricant is emitted from the holes in the high pressure tubing.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 171 words
A segmented flexible hone comprising: a high pressure helically wound tubular member having holes disposed therein and capable of being disposed in a tubular hole; a plurality of outwardly extending flexible spirally wound nylon bristles having abrasive globules attached to the outer ends thereof with the inner ends being attached to said tubular member at segments along said tubular member; said tubular member having intervals free of said bristles with said holes being located in said tubular member in the intervals wherein said tubular member is free of said bristles; a high pressure nozzle attached to said tubular member at one end thereof for conducting a lubricant through said tubular member and through said holes in said tubular member at a pressure between about 80 psi and about 2000 psi; and a rotational mechanism attached to said nozzle for rotating said tubular member while said lubricant is being conducted therethrough, thereby causing said globules and said lubricant to contact the inside surface of said tubular hole, thus enlarging said tubular hole.
Claim 2
Dependent Claim 171 words
A segmented flexible hone comprising: a high pressure helically wound tubular member having holes disposed therein and capable of being disposed in a tubular hole; a plurality of outwardly extending flexible spirally wound nylon bristles having abrasive globules attached to the outer ends thereof with the inner ends being attached to said tubular member at segments along said tubular member; said tubular member having intervals free of said bristles with said holes being located in said tubular member in the intervals wherein said tubular member is free of said bristles; a high pressure nozzle attached to said tubular member at one end thereof for conducting a lubricant through said tubular member and through said holes in said tubular member at a pressure between about 80 psi and about 2000 psi; and a rotational mechanism attached to said nozzle for rotating said tubular member while said lubricant is being conducted therethrough, thereby causing said globules and said lubricant to contact the inside surface of said tubular hole, thus enlarging said tubular hole.
Claim 3
Dependent Claim 42 words
The segmented flexible hone according to claim 1 wherein said holes in said tubular member are located approximately 0.5 inch above and below said bristles and said holes are angled at approximately 30 degrees with respect to the surface of the hole.
Claim 4
Dependent Claim 23 words
The segmented flexible hone according to claim 2 wherein said holes in said tubular member are approximately 0.013 to 0.20 inch in diameter.
Claim 5
Dependent Claim 25 words
The segmented flexible hone according to claim 3 wherein said abrasive globules are tungsten carbine globules held to said nylon bristles by a resin binder.
Claim 6
Dependent Claim 20 words
The segmented flexible hone according to claim 4 wherein said tubular member is a 300 Series stainless steel tubular member.
Claim 7
Dependent Claim 13 words
The segmented flexible hone according to claim 5 wherein said lubricant is water.
Claim 8
Dependent Claim 13 words
The segmented flexible hone according to claim 5 wherein said lubricant is oil.
Claim 9
Dependent Claim 15 words
The segmented flexible hone according to claim 5 wherein said lubricant is a water-glycole mixture.
Claim 10
Dependent Claim 13 words
The sequential flexible hone according to claim 5 wherein said lubricant is alcohol.
Claim 11
Dependent Claim 13 words
The segmented flexible hone according to claim 5 wherein said lubricant is kerosene.
