Honing:
- Honing is an abrading process mostly used for polishing bored and reamed holes and external cylindrical surfaces using bonded abrasive stones (called hones).
- Honing is, in fact, a cutting operation and is used to remove material less than 0.25 mm but sometimes it is used to remove stock up to 3 mm also
- The honing is mainly used to correct some out of roundness, taper, and tool marks left by previous operation or axial distortions
- Honing is done by means of bonded abrasive grit sticks (of aluminium oxide or silicon carbide) applied to the surface to be honed under controlled pressure and with a combination of rotary and reciprocating motions of abrasives
- Most honing is done on an internal cylindrical surface, such as automobile cylindrical walls.
-
After the stock removed by honing, the allowable tolerance is between 0.005 mm to 0.5 mm
