The research tests of abrasive finishing of Inconel 100 and CPW 41 alloys carried out at the Institute of Advanced Manufacturing Technology (IOS), with the superhard grinding wheels with the vitrified, resinous and galvanic bonds, were discussed. The research tests of grinding of Inconel 100 (with the cBN grinding wheels) and CPW 41 (with the diamond grinding wheels) alloys, in dependence of the grinding wheels characteristic, parameters and conditions of grinding, were presented. The applied types of the cooling liquids and the method of delivering them to the grinding /one influence on the machined surface and condition of the grinding wheel active surface (GWAS). The 2D measurement results (Ra, Rz parameters) of the samples surface after grinding and achieved material removal rates of grinding Qw [mm3min] confirmed correctness of the CBN and diamond grain types and grade selection. The results of tests showed the better quality of the surfaces after grinding with the grinding CBN and diamond grinding wheels with resinous and vitrified bonds with the pore-forming constituent content.
