Chamber treatment of detail surfaces by unfixed polishing material

Introduction. For finish treating the details like bodies of rotation with the complex external contour trough fine-dispersed unfixed abrasive particles, many abrasive grains are used for removing metal in sealing by compressed air through elastic shell in special chamber Materials and Methods. Character of pin intraction of close-settled layer with the processed detail surface is determined by the form of abrasive grains and their cutting elements. The form of grains is different. The study of many shadow imprints of abrasive particles demonstrates what all of them are fitted into an ellipse. All particles can be shaped as rotation ellipsoid in first approaching. Results. The information provided by the study is used for determining the removal of material from detail surface by abrasive cutting grains in processing. Discussion and Conclusions. The article presents the processing methods, the grain models and mathematical dependences used for predicting the productivity of the micro-cutting process.
