Features of Honing Process
  • Improve roundness or cylindricity of the pre-processed cylinder.
  • Desired roughness of the surface is attained by using different grit size stones properly.
  • High-efficiency grinding is realized through sheet-like honing by using multi-stones.
  • Honing along the pre-processed bores does not need accurate workpiece positioning against honing axis.
  • Difficult long bore inside honing is practicable.
  • The proper crosshatch that works as a groove for fixing oil on the cylinder surface can be formed by desired angle and depth.
