3. Advantage.

Halnn superhard studied the BN-K1 CBN inserts for High hardness cast iron castings. It belongs to solid PCBN inserts. It’s advantage has four aspects:

(1) CBN content up to 90%, high hardness, good wear-resistance

(2) Adopt non-metal (ceramics) as binder to improve the heat resistance and collapse resistance of BN-K1 CBN inserts. It can withstand intermittent cutting

(3) cutting depth between 1-10 mm, to achieve heavy-duty cutting, improve production efficiency

(4) dry cutting, to achieve clean production, to reduce production costs.
