Honing Process and its Applications

The honing process is carried out by mechanically rubbing the honing stone (cutting tool here) against the work piece surface (normally internal) along the controlled path. Honing can produce a surface roughness level up to 0.1 micro meters.

Level of surface finish achieved: 1.6-0.025 micro meters

Advantages:

–      Variety of materials can be chosen

–      Good surface finish

Disadvantages:

–      Equipment cost is quite high.

–      Tool wear is quite high.

Ideal applications: Ideal for finishing the internal surfaces of I.C engine cylinders, hydraulic cylinders and other cylinders where retention of lubricants film over the surface is important functionally.
