Purpose: The paper presents a comparison of the effects the processing time vibro-abrasive deburring and polishing process on the structure of the geometric surface. There is also analyzed the relationship between the duration of the treatment on the quality of sharp edges. Design/methodology/approach: Following the tests, the surface roughness and waviness of the machined job 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. Smoothing vibratory was carried out on the machine SMR-D25, which is discussed in study. Findings: Two types of treatment were analyzed by using a vibro-abrasive deburring and polishing. The first vibratory process - dry deburring was performed by using ceramic media CB 0815 VH Series. The degree of aggressive of ceramic given by the manufacturer is 24%. The second process- the vibration-surface polishing was performed by using the fittings with white porcelain series EB 0610.The process was carried out by using liquid supportive Series ME L100 A22/NF. Research limitations/implications: Analysis of the vibration smoothing technology in terms of technical refers mainly to comparethe results of the geometric structure of the surface. Originality/value: The 3D analysis of the surface topography for all samples was carried out. Deburring and polishing processes were compared.
