SUMIBORON CoatedUncoatedInterrupted CuttingContinuous Cutting HeavyLight Finishing FF SUMIBORON / Coated SUMIBORON Grade Guidance Hardened Steel HARDENED STEEL MACHINING ● Advantages of SUMIBORON for hardened steel cutting Below is an analysis of the use of CBN tools compared to grinding. In terms of cost, not only is the investment involved for introducing new machinery reduced, it is possible to shorten the processing cycle time by finishing complicated shapes in one run. In terms of quality, machining with a single chuck is possible, improving machining accuracy and squareness. Furthermore, dry machining is possible, with various advantages such as better global environmental conservation and resource recycling. The workpieces shown in the table to the lower right have shapes more likely to benefit from being cut, especially compared to grinding.
