Abstract:For the study of the polishing process characteristics of rectangular mobile frame by secondary planet abrasive polishing machine,the rectangular workpiece with the same appearance of mobile frame was used to carry out the polishing process experiment.The influence law of the main technological parameters on the workpiece surface quality,including the polishing time,the polishing speed,abrasive particle size,was systematically studied.The experimental results show that in using the 8# walnut grain abrasive,polishing time of 90 min,the polishing speed of 75 r/min,the surface polishing quality is better,and edge roughness difference is smaller.
