FMD 'METAL BOND' DIAMOND MESH SIZES
FMD - 'metal bond' type mesh sizes
FMD products include a full range of 'metal bond' type mesh sizes in varying degrees of toughness, from irregularly shaped and friable to the toughest products. They are suitable for metal bonded and electroplated tools and wheels. This product range is produced by IDF Superabrasives, with whom we hold exclusive European distribution agreements.
FMD-20 is an irregularly shaped and sharp abrasive ensuring excellent particle retention. It is effective where low cutting forces are required, for metal and electroplated bonds, in applications such as glass and ceramics grinding, gemstones and cast iron grinding.
FMD-20 Uncoated Density: 3.52 g/cm3 FMD-40 is an angular and sharp abrasive ensuring excellent particle retention, slightly tougher than FMD-20. This product is recommended for electroplated and metal bonded tools, in low impact applications such as glass and ceramics grinding, gemstones and cast iron grinding.
FMD-40 Uncoated Density: 3.52 g/cm3 FMD-40N56 56% nickel coated Density: 5.12 g/cm3 FMD-60 is a medium tough abrasive, with a majority of well-shaped, sharp particles ensuring good particle retention. It is recommended for metal bonded and electroplated tools and is suitable for flat glass grinding, pencil edging and chamfer grinding in the auto-glass and mirror industries.
FMD-60 Uncoated Density: 3.52 g/cm3 FMD-70 contains very blocky, cubo-octahedric particles, with relatively high toughness and thermal resistance. This product offers a good balance between material removal rate and wheel life. It is suitable for glass chamfering and pencil-edging, as well as for tungsten carbide grinding applications.
FMD-70 Uncoated Density: 3.52 g/cm3 FMD-80 is made of whole, well-shaped cubo-octahedric particles containing few inclusions, with very high impact resistance and high thermal stability. This product is recommended for drilling tools, for decorative grinding on glass, as well as ceramics, granite and cast iron grinding.
FMD-80 Uncoated Density: 3.52 g/cm3 FMD-80T2 2% titanium coated Density: 3.59 g/cm3 FMD-80TN56 56% nickel/titanium coated Density: 5.12 g/cm3
|FMD Diagram of relative particle shapes and friability properties: Each of the FMD products is shown here in relation to its particle shape and toughness. These properties guide the cutting power and wear resistance of metal bonded tools. Particle shape also requires suitable particle retention properties, from very strong for perfect crystals (electrometallic, metallic or brazed bonds), to average for the more angular particles (in metallic or ceramic bonds).|
