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.

Dependent claims

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.
