Rough honing process for boring surface involves offsetting longitudinal axis of boring before honing from that of finished boring

摘要

The rough honing process is for the surface (3) of a boring (2), using a honing tool (5) with honing bar (7) on a spindle (6). The longitudinal axis (MA) of the tool is offset from the longitudinal axis (MB) of the initial boring. During honing, material is honed off till the difference is eliminated and the two axes are co-axial.
