In centrifugal barrel finishing, it is easy to establish the optimum working conditions for different workpieces. As they are adjusted in trial and error practically, production efficiency and quality are some- times low In the present paper, firstly, installation of the barrel finishing machine, finishing purpose and working conditions have been analyzed in order to eliminate the defects of the finished surface. Secondly, on the basis of this result, quantity of the water and selection of the media and the compound, etc. have been investigated. As a result, production efficiency and quality have been improved under the specified optimum working conditions. In addition, durability of the media and the compound has been tested experimentally. As a result, it was found that the expected life of the media is about 85 hrs and that of the compound is about 5 hrs. Besides high quality control has been achieved by newly proposed inspection at regular intervals.

Currently the technology of surface finishing is highly demanded in a wide range of industries. And many kinds of surface finishing technologies have been developed for each purpose. But it is still difficult to make a fine surface for the part which has three dimensional geometry. Now most of these kinds of complex parts are polished by hand by well skilled workers, This hand work process is inefficient and the production cost is high. Therefore it is desirable to develop a new finishing technology to solve problem In this study a new device was developed and tested in various test conditions.
