Cylinder Bore – Peak Honed

Peak honed cylinder bore surface texture

Conventionally honed, “single-process honed,” or “peak honed” surface texture is generally comprised of a crosshatched surface with fairly random peaks and valleys. For a perfectly random surface, the height of the peaks is similar to the depth of the valleys.  In single-process honing we often find that the peaks heights are slightly smaller than the valley depths due to the fact that the most extreme peaks are more vulnerable than the deepest valleys.

While this surface is the result of a single honing process, in many production processes, an initial honing process is often used to establish cylindricity and size prior to the final honing process that creates the texture.
