Walter’s CBN grade WBH30 inserts are designed for hard turning in interrupted cuts. The inserts are said to feature a reliable, high-performance substrate which exhibits excellent toughness primarily because of its good distribution of mixed CBN grain sizes.
In addition, the grade is said to offer chemical stability derived from a TiN binder that prevents crater and flank face wear. It also provides wear resistance in hardened steels due to the 65% CBN content and higher feeds.
The company says additional improvement in surface quality and stability can be realized with the advanced wiper geometry option. Walter offers the CBN grade in inserts with and without MW wiper geometry, and with a negative T-land chamfer for strength in interrupted cuts.
