Non-Standard CBN Turning Insert
What materials are CBN Turning Insert suitable for machining?
(1) High hardness cast iron (hardness HSD75 or more): such as high chromium cast iron, alloy cast iron, nickel hard cast iron, and white cast iron are all high hardness cast iron, and typical parts are rollers, industrial pumps, etc. For the BN-K1 and BN-K10 grades of high-hardness cast iron, the advantages of CBN tools are significant.
(2) High-hardness steel parts (hardness HRC45-68): such as high-manganese steel, high-speed steel, hardened steel, etc., typical parts include rolling mortar wall, high-speed steel roll, hardened gear/gear shaft, bearing, ball screw , mold, etc. BN-S10, BN-S20, BN-S200, BN-H10, BN-H21 materials for high hardness steel have obvious advantages.
(3) Ordinary gray cast iron (HT150/200/250/300): such as engine block/cylinder head, brake disc, brake drum, pulley, clutch pressure plate, etc. are all gray iron castings. BN-S300 and BNK30 grades of CBN tools enable high-speed machining.
(4) Other difficult-to-machine materials: such as F51 duplex stainless steel, iron-based powder metallurgy, Inconel 718 superalloy materials, and nickel-based, iron-based, cobalt-based and other high-hardness surfacing/spray welding/laser cladding/thermal spraying materials artifact. BN-S300, BN-S200, BN-K50, BNK30 and other materials have obvious advantages in processing applications.
Tool scheme for machining hardened steel with CBN tool
CBN is the abbreviation of Cubic Boron Nitride in English. It is very hard, with a microhardness of HV700~9800Mpa. Its hardness is similar to that of diamond, and its thermal conductivity is high. It can withstand high cutting temperatures. Quenched steel has high strength, high hardness, low plasticity, large cutting force, and high cutting temperature. It has very high requirements on tool chipping resistance, wear resistance and thermal conductivity. According to the current processing technology, CBN tools are very suitable for processing quenched steel tool.
