Honing process

Honing process "old/new"
- Previous manufacturing process of internal cylindrical honing
- 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.
