non-contact milling of materials
Scientific-Productive Complex "Edem", Kyiv, studies a perspective technology of Non-Contact Milling of Materials (NCM) for materials of various degree of hardness with the purpose of assimilation it in Ukrainian industry.
The technology NCM is protected in Ukraine by patents ¹ 10148, ¹ 10149 of Ukraine and a patent ¹ 2100082 of Russia as" A Method of Refinement of Materials in a Stream of an Energy Supplier and a Device for Rotational Milling ".
The equipment to be produced using the technology NCM will be able to provide finely divided powders of materials that have a various degree of hardness, including superrigid materials.
