Diamond is composed of pure carbon atoms, arranged in a very special crystal orientation that gives it its unique physical properties. The physical properties of the diamond tools, specifically the extreme hardness and wear-resistance, make Motherson PCD tools so unique. In year 1978 , Sumitomo Introduced first sintered poly-crystalline diamonds (PKD) "SUMIDIA". Since most automobile components are made from the latest generation of hard and wear-resistant materials, both ferrous and non-ferrous, a growing need for tools that are abrasion-resistant and can withstand these machining applications. Polycrystalline Diamond Motherson PCD tooling is meeting these needs with an overwhelming success. From these machining applications, mainly on non-ferrous materials, Motherson PCD tools touched numerous industries, proving to be ideal solution for finishing and roughing application in turning , milling , drilling and end milling for automotive engine parts like transmission case, cylinder head, piston, cylinder block, connecting rod, oil pump housing and so on.
