Honing process

Engine housing
Honing process "old/new"

  1. Previous manufacturing process of internal cylindrical honing
  2. New manufacturing process of form honing

The cylindrical bore hole of a combustion engine becomes deformed during the operating condition by thermal loads. Form honing allows this deformation to be achieved in production, so that there is an almost cylindrical shape in the operating condition. This has a positive effect on the emissions quality, oil and fuel consumption, as well as output and wear.
