Cylinder liner honing is a process that is generally undertaken to give a smooth finish to the liners. The demands for decreased environmental impact from vehicles have resulted in a greater emphasis being given to ensuring a decreased engine oil and fuel consumption. As is common knowledge, the engine oil consumption to a great extent depends upon the topography of the cylinder liner surface, thus honing of cylinder liners is a necessity today.
Cylinder liner honing is done by using a special tool, known as a honing stone or a hone. It is generally made up of abrasive grains bound together with an adhesive. The aforementioned grains are shaped irregularly, with their size generally ranging from 10 to 50 micrometers in diameter. One noteworthy thing here is that the stones used for honing are susceptible to being friable( tendency of a solid substance to break into smaller pieces). To counteract this friability, honing stones are generally treated with wax or sulfur.
Metals Used to Create Honing Stones :
Cubic boron nitride
Please note that the above mentioned list of metals used for creating honing stones is not exhaustive but contains only the preferred ones. To be articulate, any abrasive material may be used to create a honing stone.
Some Facts About the Cylinder Liner Honing Process :
Honing is a high precision process and thus is also comparatively expensive. Another fact about the honing process is it generally is the last manufacturing operation before the final product is shipped.
In layman's term, honing is undertaken to improve the following attributes of the liners
