In the cutting process, when the cutting edge leaves the material, burrs are often formed on the edges of the workpiece. Due to inconveniences associated with burrs, such as problems with properly fixing the workpiece on the machine for further processing or problems with parts working in assemblies, deburring operations must be performed. In addition to that, burrs may pose danger for workers at the production stage and for customers at the stage of using the finished product. One of the popular deburring methods is brushing. Apart from deburring, brushing can be used to change surface layer properties. The aim of this study is a comparative analysis of the effect of machining with wire and ceramic brushes on microhardness and the surface quality of EN AW-7075 aluminium alloy. Results show that, for all defined brushing conditions, lower surface roughness parameters are obtained when using ceramic brushes rather than wire brushes. In contrast, the use of wire brushes leads to increased microhardness of the surface layer.
