Spiral slide honing from NAGEL
Spiral slide honing, developed by the NAGEL company is a further development of the 3-stage honing process, considerably reduces the amount of friction and oil consumption in comparison to conventional plateau honing.
Spiral slide honing effects an enhanced narrowing of relevant surface parameters. This enables a significant reduction in the fluctuation range of oil consumption and friction in series engines.
A consistent surface finish over the whole of the cylinder block area ensures constant tribological conditions. This in turn enables the reduction of the negative effects of static and dynamic bore distortion in later operation. This has been verified in long-term tests with a running time of up to 3000 hours.
