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.
