Higher efficiency with BN-K1 solid cbn inserts rough machining rolls

Higher efficiency with BN-K1 solid cbn inserts rough machining rolls For cast rolls, we all know that the surface allowance will be not uneven, and it often has sand, Stomata, hard point ect defects, carbide insert can’t suit the process, and the cutting speed can’t improve, which will lead to the tools wear fast. It affects the production efficiency and the production surface quality. With long term practice and research, Halnn research BN-K1 and BN-S20 solid cbn inserts,
