A set of grinding discs consists of a fixed and a rotating grinding disc. For efficient and contamination-free grinding processes, the grinding discs are available in 4 different materials (no undesired abrasion): The hardened steel grinding disc is used for standard applications (samples with a Mohs hardness of 3 – 6). The manganese steel grinding disc is used for standard applications (samples with a Mohs hardness of 3 – 6). As manganese steel is compacted under pressure, the material becomes harder over time. Moreover, it contains less chrome than hardened steel. The tungsten carbide grinding disc is recommended for grinding extremely hard samples with a Mohs hardness >6, like certain minerals. The zirconium oxide grinding disc is used for heavy-metal-free size reduction processes or when the natural color of the sample needs to be preserved (e. g. for dental ceramics). Please note: The grinding tool material should be harder than the sample. For further information check the “Material Analyses of Equipment & Accessories” document in the Downloads section. |
