CBN - A New Generation Cutting Tool Material

Sumitomo electric is a renowned name in the field of metal cutting tools in the category of super hard materials they are world leaders. This particular category consist of materials like CBN and PCD which are much higher on hardness scale as compared to conventional materials like carbide or ceramic. Superior mechanical properties make them ideal for machining hardened steel, Hi Speed turning and milling of cast iron, machining exotic materials where heat generation is very high while cutting and similar tough applications where there is conventionally no option but to have grinding or poor tool life ultimately higher cost.


Changing customer demands for higher productivity, lower lead time for component supply by reduction in cycle time, reduction in idle time like tool setting time by better cutting tool material made sumitomo think and develop tooling material as well as engineering solutions to upgrade CBN grades. Our goal is to help you remain competitive in your rapidly changing manufacturing industry.


Motherson CBN Tools are most ideal for following application areas:

PCD - Non Ferrous Machining - Roughing To Finishing

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.


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.

Sumitomo's years of accumulated application knowledge, hundreds of case studies and solutions for machining problems can be applied to Indian Non-Ferrous component maufacturers to achieve higher productivity and output from their hi-tech machine tool with the help Motherson PCD.
