Purpose The purpose of the article is to investigate the influence of deburring by wire brushing upon states of magnesium alloy edges. Design/methodology/approach AZ91HP and AZ31 magnesium alloy samples were machined with the use of recommended, catalog milling parameters. Burrs formed at the edges after milling were removed by brushing. Three different kinds of brushes were tested. Edge states (values of edge radius) after wire brushing were specified. Surface roughness was measured near the brushed edges. Findings Experimental results show that wire brushing is an efficient deburring method, which can be fully automated on machining centers. Depending on the requirements, specific values of edge radius as well as surface roughness may be obtained. Practical implications The article will help technological process designers select tools for deburring after milling of magnesium alloys. Originality/value The paper presents the automated deburring method which can provide the required edge radius of aerospace components.
