Halnn CBN Insert rough machining Ni-Cr alloy rolls
Part 1 Ni-Cr alloy rolls hard to machine problem
Ni-Cr alloy roll is a kind steel roll which contains Nickel and Chromium elements. The main difficult problem is its high hardness and large allowance. And its hardness can reach HRC57, machining allowance is large and belongs to roughing process. If use traditional cutting tools, it will appear severe wear and tear phenomenon. It required high on cutting tools hardness and wear-resistance. Currently, only CBN Inserts suit for large allowance rough turning high hardness Ni-Cr alloy roll.
Part 2 Halnn CBN Inserts for rough machining Ni-Cr alloy Rolls
Specific to machine Ni-Cr alloy roll, Halnn recommend to BN-S20 Solid CBN Inserts, the advantages are as follows:
(1) BN-S20 was specially researched for machining high hardness steel parts.
(2) BN-S20 belongs to solid CBN Inserts, so it can large allowance rough turning Ni-Cr alloy roll, and can feed the whole insert.
(3) BN-S20 Solid CBN Insert has high hardness, well wear-resistance, and the tool life of each tip can reach to 3 hours.
(4) BN-S20 Solid CBN Insert has good hot red hardness, it is normal phenomenon to appear sparks in the turning process, and it doesn’t need add cutting fluid to lower temperature.
Part 3 BN-S20 Solid CBN inserts machining Ni-Cr alloy roll
Machining Part: steel iron roll
Material: Ni-chromium alloy
Hardness: HRC57
Machining Part: Cylindrical
Inserts Grade: BN-S20 SNMN120712
Tool Holder: CSSNR2525M1207
Cutting Parameters: Vc = 45m/min, Fr=0.15mm/r, ap=1.5mm
Machining Effect: When machining parts with large allowance, BN-S20 Solid CBN Inserts will be not chipping or wear, which extend the lifetime and improve the producing efficiency.
