6726546, Apr 27, 2004
Filed:

Jan 9, 2003
Appl. No.:

10/339173
Inventors:

David A. Christian - North Manchester IN
David J. Lucas - Warsaw IN
Charles R. Hileman - Mentone IN
Buddy Kuczewski - Warsaw IN
Charles M. Williams - Etna Green IN
Assignee:

Zimmer Technology, Inc. - Chicago IL
International Classification:

B24B 700
US Classification:

451 65, 451342, 451343, 451461
Abstract:

A method and apparatus for deburring nonmetallic machined workpieces. A deburring material of sufficient hardness to debur nonmetallic workpieces without causing scarring thereto is rubbed against a workpiece to effect deburring. The deburring material has a durometer hardness and consequently a coefficient of friction whereby frictional engagement of a burr with the deburring material is stronger than the attachment of the burr to the workpiece and therefore the burr is removed as the deburring material is actuated and brought into contact with the burr. The deburring material can be, e. g. , polyisoprene and may be mechanically actuated or actuated by hand.
