Cylinder Hones and Honing - KITPLANES

http://www.flexhoneblog.com/2010/04/honing-tools-for-two-stroke-engines.html WebThe honed cylinder bore crosshatch angle determines ring rotation speed and its ability to promote proper oil migration up and down the cylinder wall. Most general application blocks use a 45 degree (included) angle, which is measured as half of that from a horizontal plane. ray schnell for tustin city council

Specification and Measurement of Plateau Honed Surfaces

WebApr 23, 2010 · The idea is that a positive cross hatch angle helps the lubrication wick up the cylinder walls which is important in internal combustion engines in general and is 2-cycle engines specifically. In other applications like journal bearings just the opposite is true. A shallow cross hatch angle is desired to prevent lubrication migration. WebThe optimum crosshatch angle is typically 45 degrees. Most OEMs and ring manufacturers suggest the angle of the scratches in the crosshatch pattern be between 27 - 45 … WebThree types of cylinder bore surface texture. To control the honing processes, we need to monitor several aspects of the surface texture. We also need to monitor the crosshatch angle—the angle between the texture created by the hone as it passes down the bore, and back up the bore. ray schober designer
