Sandblasting is mainly directed to destructive process on the metal surface. Use abrasive to impact the metal surface, let surface occur a depression like granulate,goal is to produce atomized metal surface etching and removal of flash effect。
This study focuses on the sand blasting technique with a magnetic,and select aluminum 6061 for processing materials,with soft texture and folds of the phenomenon of post-processing,can shorten processing time of sandblasting,observed in the corresponding magnetic surface roughness of sandblasting processing trends, further study of magnetic properties and processing of sandblasting on the surface。
first, arrange the preliminary experiment and L18 experiment, to do planning for the processing parameters of the magnetic sandblasting, if magnet placed way (vertical or yaw)and nozzle angle and nozzle distance and the distance of magnetic and magnetic intensity and spray on the processing results (roughness and removal rate and processing range) effects。
Preliminary experimental results point to a fixed processing time and nozzles angle. Because the angle of the nozzle effect processing area and region, less affected of roughness, processing time is due to be processed 6061 aluminum folds of the phenomenon, and shorten the processing time to observe the processing trends.
Then by the L18 results the nozzle distance and distance of magnetic as the variable at the same time, magnet processing parameters associated with no significant contribution, therefore fixed the angle of the nozzle and nozzle distance at follow-up single factor experiments。
The single factor experiments results can be obtained from the magnetic configuration corresponding to the roughness of the trend, the configuration of the jet pressure 5kgf, magnetic intensity 550mT and magnet distance 80mm and when the magnet yaw will be the best performance of the roughness，and get near the magnet end of processing areas will have better performance of the conclusions of the roughness, then used with equation obtained by the regression equation, follow-up can be estimated using the formula in advance of the roughness of the different magnetic configurations, effectively eliminating the number of experiments, and accelerate to find the optimal results。
