What is Honing?

Honing is a finishing process used on the surface — either exterior or bored — of a component to perfect the geometry and finish so it can perform as required. Honing creates the exact final sizing of a core and can create the desired finish or even pattern on a surface. The process of honing is enacted through the use of degradable stone applied to the surface of the component to achieve the desired finish. These stones can be rotated and/or reciprocated to create the necessary pressure for the right kind of finishing hone.

By removing the stock, creating the proper surface, and providing for extremely accurate straightness and roundness, proper honing promotes an optimal liquid flow across the interior or exterior of a component as well as reducing friction, shearing, and stress against other parts.
