Boring bars are used for enlarging an existing drilled hole. Even though we have fine finish boring bars, its surface finish will be poor compared to other finishing processes.A comparatively large amount of material is removed in this process.
Reamers are used for finishing an existing hole. we can get up to N6 finish by reaming and an Ra up to 0.8.
Lapping is a super finishing process where abressive powder is rubbed against the surface in a lubricating environment. We can get below N5 finish through this process.
