BECKER Sandwich CBN Grades & Cutting ParametersBECKER ISO Composition - Performance Application

PBC-15S BH-C Coated PcBN grade with high content of CBN (90%) in sandwich performance. Fine grain, high wear resistance and toughness at lower cutting speed than with PBC-10S.

Nodular cast iron • Grey cast ironSintered powdered alloys • Super alloys

PBC-40S BL-C Coated PcBN grade with low content of CBN (55%) in sandwich performance. Super fine grain, very high wear resistance, compressive strength and toughness for hard turning with continuous to extremely interrupted cut.

Hard turning, dry + wet • HRc = 48 - 65 ap = 0.002" - 0.020" • Ra = 4 - 125 RMS
