The materials and parts produced by powder metallurgy are of high quality, low cost, energy efficient and material saving, and are therefore widely used in industries such as automotive manufacturing, electronics and machinery manufacturing.

The porous structure is one of the characteristics that makes powder metallurgical parts so widely used, but the high porosity reduces the machinability of powder metallurgical parts, as the tool is damaged by the porosity, reducing tool life.

CBN tools are ideal for the machining of powder metallurgical parts, as a type of superhard tool developed for the turning of hard parts, and are characterised by their high hardness, wear resistance and high speed cutting performance.

WSS has accumulated a large number of machining solutions for workpieces such as powder metallurgy tooth discs, tooth sleeves and clutch discs. Turning and interrupted finishing of gear end faces and internal circles, one tool solves several machining needs at the same time. Under suitable machining parameters and good machine conditions, WSS CBN tool life is very good and the choice of WSS CBN tools can significantly reduce the cost per part.
