Platform honing of cylinder bore surface of engine cylinder block

2023/7/21

  The so-called platform reticulate honing means that tiny grooves are formed on the surface of the cylinder hole after honing and grinding, and these grooves are regularly arranged to form reticulate patterns, and the peaks of the grooves are cut off by a special honing process to form a tiny platform.

  Zhengheng Power is an enterprise specializing in the production of engine cylinder blocks. We mainly use platform reticulate pattern in honing cylinder holes. (as shown in figure 1)

  Because this special structure formed on the surface of cylinder hole by platform reticulate honing has the following advantages:

  1. The tiny platform increases the contact area, cuts off the peaks, eliminates the early rapid wear of the surface and improves the wear resistance of the surface.

  2. Fine groove marks form a good oil storage space, which reduces the friction between the cylinder hole surface and the piston.

  3. The fine groove marks form a good oil storage space, which reduces the loss of oil, thus reducing the consumption of engine oil.

  4. After honing, countless tiny platforms are formed on the surface of the cylinder hole, which increases the contact area between the cylinder hole and the piston, increases the support of the cylinder hole surface, and reduces the initial wear of the cylinder hole, thus reducing the running-in time of the cylinder hole.
