The problems on machining Ni-Chrome (Ni-Cr) Alloy Rolls
The Ni-Chrome(Ni-Cr) Rolls means that the steel rolls which include Nickel and Chrome element. The difficult problem is high hardness and large working allowance. The hardness will reach HRC57, and it belongs to roughing process, traditional cutting tools will wear seriously. It will require high on the cutting tools hardness and wear resistance. In current times, the most suitable cutting tools for rough machining Ni-Cr alloy rolls must be cbn insert.
Specific for Ni-Cr Rolls, Halnn recommend BN-S20 solid cbn insert, the advantages as follows:
(1) BN-S20 is researched specific for high hardness steel parts;
(2) BN-S20 belong to solid cbn insert, it can be used for rough machining Ni-Cr Alloy Rolls with large allowance.
(3) BN-S20 has high hardness, good wear resistance, each tip can work more than 3 hours when rough machining Ni-Cr Rolls.
(4) It has good high temperature red hardness, no need adding cutting fluid which will reduce the environment pollution.
