Good honing has a positive effect on piston ring wear, particle emission, oil consumption and friction.

With further developments and innovations in the honing of cylinder liners, the goal is to keep the running-in phase of the cylinder (engine) as short as possible and achieve improved tribological properties. An important prerequisite for consistent quality honing of the cylinder liners is high material quality. This requires cast material free of voids, with homogeneous structure and uniform hardness, as well as suitable pre-machining of the bore.

Honing
Method of machining, in which the tool carries out reciprocating and rotating movements. With this method, a cylinder form error below 10 ìm and an even surface.

Tribology
The science of friction, lubrication and wear of bodies in relative motion.
