1. Higher hardness and abrasion resistance
Single crystal CBN microscopic hardness is HV8000 ~ 9000. It is a substance that is known after diamonds after diamonds, and its complex hardness is generally HV3000 ~ 5000.
2. Good thermal stability and high-temperature hardness
The highest heat resistance of CBN can reach 1500 ° C. At 800 ° C, the hardness of CBN is the normal hardness of Al2O3/TIC ceramics.
CBN is more advantageous than PCD because it has high-temperature resistance.
3. Excellent chemical stability
CBN has a high antioxidant capacity. At 1000 ° C, it does not produce oxidation. At 1200 ～ 1300 ℃, CBN will not have a chemical reaction with iron materials.
4. Have good thermal conductivity and lower friction coefficient.
CBN inserts are suitable for processing workpiece materials:
1. High-hardness cast iron (hardness HSD75 or more)
Such as high -chromium cast iron, alloy cast iron, nickel hard cast iron, and white mouth cast iron are all high-hard cast iron. Typical parts include rollers and industrial pumps.
2. High-hardness steel parts (hardness HRC45-68)
Such as high manganese steel, high-speed steel, quenching steel, etc. Typical parts include high-speed steel rolls, hard gear/gear shafts, bearings, rolling screws, molds, etc.
3. Ordinary gray cast iron (HT150/200/250/300)
Such as the engine cylinder/cylinder head, brake disc, brake drum, belt wheel, clutch plate, etc. are all gray cast iron.
4. Other difficult processing materials
Such as powder metallurgy, high-temperature alloy materials, nickel-based, iron-based, cobalt-based high-hardness pile welding/spray welding/laser melting/hot spray materials workpieces.
has much experience in designing, developing, manufacturing, and application of superhard cutting tools, which are widely used in Involving aerospace, automotive, medical, electricity, energy, natural diamond and jewelry industry, and high-tech industries.
Since its establishment, More SuperHard has been committed to providing customers with high-quality Products.
