Significant effect with BN-S20 solid cbn inserts machining rolls

Significant effect with BN-S20 solid cbn inserts machining rolls For the rolls with hardness above HSD75, it requires high on the cutting tools impact resistance, impact high temperature, impact resistance because of the high hardness and other cast defects. Traditional carbide alloy insert will wear seriously, we recommend Halnn BN-K1 solid cbn insert, which not only keep the good wear resistance of cbn inserts, but also have excellent wear resistance, and can rough
