The paper presents influence of the main dimension of smoothing media used in the vibro-abrasive machining for geometric structure of the machining surface parts made of aluminum alloy EN AW-2017A. There were used Rollwasch smoothing media PB series -- polyester bonded. The factors causing the surface roughness have also been taken into consideration. Attention has also been given to the relation between the properties of abrasive media and the surface roughness. Media were cone-shaped, with different abrasive properties. The process was conducted for three frequencies of tumbler: 2000 Hz, 2500 Hz, 3000 Hz and time of machining 60 minutes. The surface roughness and waviness of the machined parts were measured by using optical profilometer Talysurf CCI Lite -- Taylor Hobson. To illustrate the surface taper ratio and edge optical microscope Nikon MA 200 Eclipse with the image analysis system NIS 4.20 was used. Analysis of the vibration smoothing technology in terms of technical refers mainly to compare the results of the geometric structure of the surface. The process was carried out by using liquid supportive series ME L100 A22/NF. Finally, the 3D analysis of the surface topography for all samples was carried out. In this paper, removal of edge burrs is reported.
