—Honing is a finishing process, in which a tool called
hone carries out a combined rotary and reciprocating motion while the workpiece
does not perform any working motion.
—Most honing is done on internal cylindrical surface,
such as automobile cylindrical walls. The honing stones are held against the
workpiece with controlled light pressure. The honing head is not guided
externally but, instead, floats in the hole, being guided by the work surface.
—It is desired that
1.
Honing stones should not leave the work surface
2.
Stroke length must cover the entire work length.
3.
In honing rotary and oscillatory motions are combined to produce a cross
hatched lay pattern.
—The honing stones are given a complex motion so as to
prevent every single grit from repeating its path over the work surface.
