Title: Study of a New Internal Finishing Process by the Application of Magnetic Abrasive Machining. Development of an Abrasive Slurry Circulating System and Its Effects on the Finishing Characteristics.
Abstract: An internal magnetic abrasive machining uses a specialized magnetic abrasive, consisting of Al2O3 abrasive grains and iron, as a finishing tool. Because of the particular process used to produce the magnetic abrasive, it is difficult to control the size of the Al2O3 abrasive grains in the magnetic abrasive. This affects not only the finishing characteristics, but also the applicability of the process. The effective life of the magnetic abrasive, caused by the wear of the Al2O3 abrasive cutting edges, must also affect the finishing characteristics over the processing time. This research, thereby, processes the application of a commercialized abrasive slurry as a finishing tool in place of the specialized magnetic abrasive. The aim of the paper is to present the principle of the finishing process using an abrasive slurry and examine the finishing characteristics. The fine surface of 0.01μ mRa in roughness (SUS304 stainless steel tube) was obtained using this abrasive slurry circulating system. These results will characterize the finishing mechanism.
