This paper presents the analysis of surface texture after grinding of sintered tungsten (WC) and silicon carbides (SiC). The properties and application of sintered carbides, as well as the selection of machining parameters during the grinding of these materials were presented. The literature survey related to the analysis of surface texture after grinding of sintered carbides was also carried out. The analysis revealed that grinding speed and depth, as well as grain size and carbides' manufacturing method have significant influence on the surface roughness parameters' values. This paper can be also the starting point to the further research on grinding performance analysis of sintered carbides during cutting with tools with defined geometry.

Celem prezentowanych badań była analiza struktury geometrycznej powierzchni węglików spiekanych: wolframu (WC) i krzemu (SiC) po szlifowaniu. Przedstawiono właściwości i zasto-sowanie węglików spiekanych, a także dobór parametrów obróbkowych do szlifowania tych materiałów. Omówiono literaturę dotyczącą analizy struktury geometrycznej powierzchni węglików spiekanych po szlifowaniu. Analiza wykazała istotny wpływ prędkości i głębokości szlifowania, a także wielkości ziarna węglików i technologii ich wytwarzania na chropowatość powierzchni. Może to być punkt wyjścia do dalszych badań skrawalności węglików spiekanych podczas obróbki narzędziami o zdefiniowanej geometrii.
