cbn cutting tool material is cubic boron nitride. Cubic boron nitride is synthesized by hexagonal boron nitride and catalyst under high temperature and pressure. It is another new product after synthetic diamond.
With high hardness, thermal stability and chemical inertness, as well as good infrared permeability and wide band gap width and other excellent performance, its hardness is second only to gold steel stone, but thermal stability
It is much higher than Jingang, and has greater chemical stability to iron series metal elements. Therefore, cubic boron nitride, as a superhard tool material, can be used to process ferrous metals such as steel and iron.
Especially processing high-temperature alloy, steel and cold cast iron and other difficult materials, but also very suitable for CNC machine tool processing.
CBN stands for Polycrystalline Cubic Boron nitride. High hardness, microhardness HV700~9800Mpa, similar to diamond hardness, high thermal conductivity, can withstand high cutting temperature.
Hardened steel has high strength, high hardness, low plasticity, large cutting force, high cutting temperature, high requirements for tool pressure resistance, wear resistance, heat conduction, according to the current processing technology,
The CBN tool is ideal for machining hardened steel tools.
Materials suitable for processing
High hardness cast iron (hardness HSD75 or above) : such as high chromium cast iron, alloy cast iron, nickel cast iron, white cast iron for high hardness cast iron, typical parts are rolls, industrial pumps, etc.
High hardness cast iron BN-K1 and BN-K10 materials, CBN cutting tools have significant advantages.
High hardness steel (hardness HRC45-68) : such as high manganese steel, high speed steel, quenched steel, etc. Typical parts are rolled mortar walls, high speed steel rolls, hardened gears/gear shafts, bearings,
Ball screw, mold, etc. For high hardness steel BN-S10, BN-S20, BN-S200, BN-H10, BN-H21 material advantage is obvious.
Ordinary gray cast iron (HT150/200/250/300) : such as engine cylinder block/cylinder head, brake disc, brake drum, pulley, clutch pressure disc and so on are gray cast iron.
Bn-s300 and BNK30 CBN tools can achieve high speed machining.
Other difficult materials: such as F51 duplex stainless steel, iron based powder metallurgy, Inconel 718 superalloy materials, nickel based, iron based,
Cobalt base and other high hardness surfacing/spray welding/laser cladding/hot melt spraying material workpiece. BN-S300, BN-S200, BN-K50, BNK30 and other materials processing and application advantages are obvious.
