dc.description.abstract Příspěvek pojednává o možnostech použití sintrovaného korundu při broušení dílů nářadí. Hodnotí vliv technologických podmínek na řezné síly při broušení, na opotřebení nástrojů a na jakost obrobených ploch za předpokladu změny koncentrace zrn sintrovaného korundu v brousicím kotouči. cs
dc.description.abstract The paper deals with the use of sintered corundum in grinding of tools. It evaluates the impact of technological conditions on cutting forces during grinding, the tool wear and quality of machined surfaces, provided changes in the concentration of grains in sintered corundum grinding wheels. Sintered corundum is a type of artificial corundum, where the feedstock is aluminiummonohydrate which, after merging with Al-dispersion granules of desired size of grains and the subsequent process of acquiring the final strength and surface hardness. Under external loading of the grinding wheel grains separated by a variety of large crystalline fragments and thus produce more grain for sharp points and cutting edges. Among the advantages of the new abrasive is rustiness and thus lower the frequency of dressing and longer life. Of sintered corundum abrasive is designed for grinding hard and very tough materials (hardness of 48HRc, HSS, etc.). The introduction of grinding wheels with greater porosity is considerable technological and economic benefit. Advantageous is also adding to the sintered corundum grinding wheel. This adjustment significantly improves the rustiness tools. It should be emphasized that the use of new grinding wheels with higher porosity and higher content sintered corundum leads to the deterioration of the arithmetic average roughness of polished surfaces. This disadvantage must be reducing the intensity of technological conditions. en
