Chamber treatment process of disks and fists

Introduction. The article describes the processing of different surfaces of details by unsupported polishing material. High efficiency of finish process with difficult profile can be attained by unsupported polishing material close-settled in a chamber static pressure of the compressed air through an elastic shell. Materials and Methods. The researches of treatment quality of disks and fists were carried out on experimental install. The workpieces are fixed on a special snap eccentrically located in the spindle unit. The chamber makes reciprocating movement at a certain speed and amplitude in order to improve the quality of the processed surface. Results. The article presents mathematical models to determine the cutting speed when parts rotating relative to the fixed manufacturing environment. The author describes the methods of the processing in order to achieve a predetermined surface roughness value. Discussion and Conclusions. The stability of the polishing process is supported by possibility of contact of complex surfaces with the dense abrasive agent during time required for complete revolution of the rotor about the central axis. The abrasive agent has time to react to the changing shape of the part profile.
