Need to further improve the internal machining accuracy and surface roughness

For an aspect ratio greater than 5, 4-20mm diameter cylindrical hole mass parts finishing requirements, compared with electroplated CBN honing precision boring, grinding and honing  abrasive wheels . But with the development needs of precision parts, need to be further improved bore machining accuracy and surface roughness. Honing tool is reduced by deformation processing quality bore key factor, but by having the structure deformation, and the honing process decided by the force  abrasive grinding  is not clear, and  abrasive wheels  having the structure of the honing process optimization is necessary. Based electroplated CBN deep processing technology status and the general theory, the paper electroplated CBN honing tool design and parameters optimization conducted in-depth research.
