W artykule przedstawiono wyniki badań zastosowania obróbki wibrościernej do usuwania zadziorów i wygładzania powierzchni tulei wykonanych ze stopu aluminium obrabianych skrawaniem. Badania przeprowadzono na urządzeniu firmy Rollwasch SMD-R 25 o objętości pojemnika 25 dm3. Określono wpływ częstotliwości wymuszeń pojemnika wygładzarki oraz agresywności kształtek ściernych. W badaniach użyto kształtek ściernych o spoiwie poliestrowym o różnych stopniach intensywności ściernych. W celu oceny efektów obróbki dokonano pomiarów struktury geometrycznej powierzchni. Określono wpływ czynników procesu na końcowy efekt wygładzania powierzchni tulei ze stopu EN AW-2017A (AlCuMg1, PA6).

The article presents an analysis of the possibility of applying vibro abrasive machining for smoothing the surface of aluminum alloy. The impact of the frequency and aggressive-ness of abrasive shapes were compared. Tests were performed on a machine Rollwasch SMD-R 25 with a tumblers capacity of 25 dm3 Were used media abrasive related polyester with different intensities abrasives. For smoothed samples was performed measurements the geometrical surface structure. Defined the effect factors on the final result of the process of smoothing the surface of an aluminum alloy EN AW-2017A (AlCuMg1, PA6).

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.
