Abstract
A honing tool or mandrel mountable for rotation on a honing machine comprising an elongated substantially tubular member having inner and outer surfaces, the inner surface being conically tapered over substantially the length thereof, the outer surface including a portion having abrasive particles thereon, an elongated expander member positioned extending through the tubular member and having an outer surface tapered for making surface-to-surface contact with the tapered inner surface of the tubular member, the expander member being axially movable within the tubular member to change the diameter thereof uniformly along its length, the tubular member being attachable to a honing machine for rotation therewith adjacent one end portion thereof by a mounting structure which enables the tubular member to expand and contract thereat to increase or decrease the diameter thereof. The abrasive particles attached to the tubular member form work engaging mandrel portions along at least a portion of the outer surface thereof, all of the work engaging portions being located on a substantially cylindrical honing envelope. The present mandrel constructions are especially adaptable for use in multi-stroke honing applications and also lend themselves to a two-piece construction including a tubular honing portion and a drive assembly portion.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
