New BN2000 CBN Grade for Hardened Steel from SumitomoMay 1, 2012
Sumitomo Electric Carbide, Inc. has introduced a new hardened steel turning advancement, the uncoated CBN grade BN2000.
"The new BN2000 CBN Grade is designed for turning die steels and bearing steels with hardnesses of 50 HRc and above. The BN2000 features a newly developed CBN substrate consisting of a ceramic binder with a high level of purity," said a company spokesperson. "While impure binders contribute to premature chipping and cutting edge wear, the purity of the BN2000 can significantly reduce tool failure.
"The BN2000 is designed for use in both continuous to medium interrupted hardened steel finishing applications. This application range makes the BN2000 suitable for even small bores that may require lower SFMs, speeds conventional CBN cannot match," the spokesperson said. "Along with its long tool life, the improved edge sharpness of the BN2000 offers customers consistent parts with the capability of attaining surface finishes as low as 3.2 Ra."
