Cylinder crosshatch angle
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. WebNikasil is electroplated onto the cylinder bore approximately 0.004-0.005” thick and is then diamond plateau honed. The crosshatch angle is typically shallower and the surface finish smoother than commonly found on steel or iron cylinder bores. During break-in, very little changes to the surface profile on a Nikasil cylinder as the piston ...

Some applications call for a steep …
WebThe crosshatch angle should be consistent throughout the cylinder walls. If the crosshatch angle is too steep the cylinder walls will not retain sufficient oil to aid in the rings seating process. The problem is that the rings will pump oil and rings will rotate too quickly leading to accelerated ring and ring groove wear. WebThe cross-hatch angle should be the same the full length of the cylinder, and while the most common angle is roughly 45 deg., it may vary depending on ring tension or stroke …
WebTo evaluate cylinder liners, three characteristics must be examined: Cross-hatch configuration Cylinder liner surface roughness Cross-hatch intersecting angle Solution The LEXT OLS5000 microscope uses lasers to perform 3D measurement of the delicate surface features of cylinder liners, which is necessary for quality management. WebMay 25, 2014 · Cross-hatch angles help determine ring rotation speed and the how easily oil is moved up and down the bore. Most typical applications run a 45-degree cross-hatch angle.
