Short stroke honing (superfinishing)

• Used in two main applications

• Most commonly used for finishing roller bearing races

• Also used in stand-alone machines for finishing shafts, tubes and cylinders

• The aim is to improve the surface finish and undulation (roundness)

• Selection of the honing stones primarily depends on the amount of material to be removed and the required surface finish

• Aluminium oxide honing stones are used to achieve higher stock removal rates and silicon carbide honing stones are used for enhanced roughness

• The grit size is determined by the outer diameter of the workpiece - the larger the workpiece, the coarser the grit
