Honing and superfinishing stones

Honing and superfinishing stones are finishing tools which are specially developed and customised by Atlantic for their respective application. In the honing process any uneven sections produced during pre-machining operations are eliminated as a result of continuous contact between the workpiece and honing stone.

Honing and superfinishing stones are manufactured from abrasive grinding media, which are held in the abrasive matrix by suitable bonding agents.
Vitrified bonds in particular have proven successful for finishing applications, as they offer the best balance between a self-sharpening effect and profile retention. Resin-bonded stones are also used in certain special applications. The bond is responsible for ensuring the grain remains on the stone until it is blunted or worn by the cutting process, after which it is released to allow the use of a new, sharp grain.

Synthetically produced grain materials are usually used as the abrasive, as they enable higher surface quality. A distinction is made between conventional grinding media, such as aluminium oxide and silicon carbide and so-called ultra-hard media, such as cubic boron nitride and synthetically produced diamond.

A honing stone is composed of an abrasive grain, bond and pores. The porosity of the stones can be filled with sulphur or wax, which prolongs the tool life of the honing and finishing tool.
