CBN Mesh Sizes
FBN - the CBN Mesh size range
The FBN product range includes a full range of both coated and uncoated CBN abrasives, in various shades of toughness and breakdown modes. The coated varieties are used in phenolic and polyimide bonded wheels, for a wide range of ferrous metal grinding applications. The uncoated product is also used in vitrified, metallic and electroplated wheels. The FBN product range is produced by IDF Superabrasives, with whom we hold exclusive European distribution agreements.
FBN-80 is the 'economy' CBN Mesh product, designed for free cutting and excellent surface finish. FBN-80 is suitable for general grinding applications, with a very good price/performance ratio, in resin and vitrified bonds.
FBN-80 Uncoated Density: 3.48 g/cm3 FMD-80N60 60% nickel coating Density: 5.26 g/cm3 FBN-90 is a black, semi-blocky and semi-tough CBN abrasive, with excellent micro-fracture properties for overall performance, grinding efficiency and surface finish.
FBN-90 Uncoated Density: 3.48 g/cm3 FMD-90N60 60% nickel coating Density: 5.26 g/cm3 FBN-150 is a medium strength, thermally stable, black CBN abrasive with added tolerance in use. It favours grinding energy reduction and better surface finish, as well as longer wheel life.
FBN-150 Uncoated Density: 3.48 g/cm3 FBN-150N60 60% nickel coating Density: 5.26 g/cm3 FBN-170 is a medium to high toughness, thermally stable, monocrystalline black CBN grit. It is suitable for some more demanding applications in terms of toughness and material removal rates.
FBN-170 Uncoated Density: 3.48 g/cm3 FBN-170N60 60% nickel coating Density: 5.26 g/cm3 FBN-190 is a very tough and thermally stable, monocrystalline black CBN grit. It is suitable for the toughest bonds and the most demanding applications.
FBN-190 Uncoated Density: 3.48 g/cm3 FBN-190N60 60% nickel coating Density: 5.26 g/cm3
FBN-130 is a semi-blocky to blocky, amber-coloured, medium-tough CBN abrasive. Its particle surfaces are specially purified for electroplated applications.
FBN-130 Uncoated Density: 3.48 g/cm3 FBN-200 is a very strong, amber to brown-coloured, tough CBN abrasive. The particle shape is angular with sharp edges, with aggressive characteristics, suitable for high performance applications.
FBN-200 Uncoated Density: 3.48 g/cm3 FBN-200TN60 60% nickel/titanium coating Density: 5.24 g/cm3 FBN-300 is a dark, amber to brown-coloured, very compact, monocrystalline CBN abrasive, the toughest of the CBN mesh products. Its high thermal stability allows it to be used in metal and vitrified bonds, as well as electroplated tools, for high performance and long tool life.
FBN-300 Uncoated Density: 3.48 g/cm3 FBN-300T2 2% titanium coating Density: 3.53 g/cm3
|This diagram shows the relative positions of the various FBN grit products on a TTI toughness (vertical) and thermal stability scale (horizontal), relative to the central FBN-150 product. From left to right, the fracture mode tends to vary from micro to macro-fracture. The combination of toughness and fracture mode offers numerous variations in free cutting properties, tool life, material removal rate and surface finish properties.|
