Abstract
Vibro-abrasive processing is the basic method for the mass finishing of parts and components in various industries. Continuous progress in the development of processing media and machine design solutions means that every research effort into vibro-abrasive processing broadens the scope of knowledge in the selection of media, parameters, and applications in various industry fields. In this paper, an attempt is made to parametrize the vibratory grinding process, which is one of the three stages of high gloss finishing. Samples of the 6082 aluminium alloy intended for use in loaded machine parts and forged car wheel rims were subject to a research analysis. The samples were processed in a rotary vibrator equipped with a sample fixing system, using resin media and auxiliary com-pounds. On the basis of the analysis, the processing capacities were determined for the selected conditions and abrasive media. The influence of time and applied processing media on the change in samples’ roughness was determined. The effects of processing were examined with the use of laser devices measuring surface roughness in the areas of 3D and 2D analysis. The analysis of the test results showed that the use of S12TZ type resin media in a 12-hour finishing process of the 6082 aluminium alloy allowed for a 75.5% reduction in surface roughness, which corresponds to approximately 6.3% per hour of processing.

Summary
Technological development and progress in the automation of processing methods is the basis for highly efficient production processes. One of the highly efficient methods of finishing is vibro-abrasive processing [6]. Vibro-abrasive processes provide a wide range of possibilities for finishing edges and surfaces of produced elements [7]. Processing with the use of loose abrasive material has found its application beginning from simple deburring processes to advanced solvent polishing or strengthening of the workpiece surface [8]. The vibro-abrasive technique can be used to process various materials, from plastics through non-ferrous metal alloys, to steel parts. Continuous progress in the improvement of various types of abrasive media and auxiliary chemical compounds is the reason for continuous optimization of the process and its parametrization [9,10,11]
