Method of producing a connecting rod especially for a combustion engine involves a first and second honing operation

摘要

A first honing operation produced a convex shape of the surface line viewed in the axial direction of the hole (5) in the small connecting of eye (4). In a second honing operation, a cylindrical section (15) of the surface line is produced and or an oval cross-sectional shape of the hole is produced during the honing operation. During a first and second honing operation, the small connecting rod eye is clamped and force is applied to the lengthwise direction of the small connecting rod eye.
