Heavy turning rolls with BN-K1 solid cbn inserts

Heavy turning rolls with BN-K1 solid cbn inserts In current times, steel industry will obtain high machining efficiency and reduce the production costs, they will choose high hardness rolls, which will be a difficult problem that machining process. It often appears lathe vibration problem and it can’t obtain good surface roughness and affect the production efficiency. Specific this problem, Halnn researched 2 types solid cbn inserts Bn-K1 and BN-S20, which not only can be
