The normal vibration directions of vibration-assisted magnetic abrasive finishing are all parallel or perpendicular to the surface of workpiece. It’s shortcomings are easily lead to more scratches on the surface, and difficult to obtain mirror effect.
A study of magnetic polishing for SUS304 with planetary bodies combined two-dimensional vibration. The main purpose of the planetary bodies of rotation and revolution characteristics, excellent surface morphology, and saving energy and time can also be reached. Series of experiments by controlling the working gap, the amplitude of the vibration platform, steel particle size and so on. This mechanism can enhance the surface quality and efficiency.
Taguchi experiment show that the combination of better parameters for the surface improvement : working gap 1 mm, the amplitude of the vibration platform 0.1mm, steel particle size of 0.125 mm , SiC weight of 3 g, steel weight of 0.5 g * 2, the weight of the slurry 5g, vibration platform frequency of 16.667Hz, magnet pole rotational speed 500 rpm (156).
For the curve improvement : working gap 0.5 mm, the amplitude of the vibration platform 0.1mm, steel particle size of 0.125 mm , SiC weight of 3 g, steel weight of 0.5 g * 2, the weight of the slurry 5g, vibration platform frequency of 16.667Hz, magnet pole rotational speed 500 rpm (156).
This mechanism can be effective in improving the stainless surface S.R. from Ra 0.23 μm to 0.058 μm, improvement rate was 74% and improving the stainless curve S.R. from Ra 0.23 μm to 0.058 μm, improvement rate was 74%. which can prove that planetary bodies combination of the two-dimensional vibration support mechanisms to improve quality.
