The given paper is focused on the analyses of surface roughness since this particular indicator of technical characteristics of the product plays the decisive role when determining the quality of component and potential service properties of the surface. As we know, during recent years research of the roughness parameters has reached a new level and it is connected with the emergence of new equipment for the 3D measurement of roughness and introduction of the new standard ISO 25178-2:2012, describing 39 parameters of surface texture for exact determination of properties of a definite surface. In view of the fact that treatment with abrasives grains is a very widely used and precise method of final treatment of components, the paper researched surfaces treated by flat grinding at different component feeding rate. As a result of the research topographies of four flat grinded surfaces were obtained and their processing – filtration using a special software µUltra was carried out. For the determination of the properties of flat grinded surfaces a mathematical model of roughness was developed, texture parameters were analyzed and also their relation to the cutting conditions was established.
