In this paper, the possibility of high precision machining was confirmed by using magnetic abrasive finishing process with rotating fine ceramic bar in high speed. Also, in order to improve the surface roughness, it was used the vibration of the magnetic pole and the mixed grain which is mixed with diamond paste for ultra precision processing and electrolytic iron powder. As a result, we knew that there is closely connected with diamond grain size, change of quantity and vibration of the magnetic pole to surface roughness of ceramic bar.

본 논문에서는 파인 세라믹 바를 고속으로 회전시켜 자기연마법을 이용하여 고정밀가공의 가능성을 확인하였다. 또한 표면 정밀도를 향상시키기 위해 전해철분과 초정밀 가공용 다이아몬드 입자를 혼합한 지립과 자극의 진동을 이용하였다. 결과적으로 다이아몬드의 입자 크기, 양의 변화 그리고 자극의 진동과 세라믹 바의 표면거칠기가 밀접하게 관련되어 있다는 것을 알 수 있었다.

Results ar presented of a new process for internal precision finishing of slender fine ceramic pipes using a magnetic field generated by a permanent magnets. For finishing the interior surface of a long pipe, a new type of finishing equipment was developed which can be very easily used in an industrial surrounding. In general, the pipe is so slender that a conventional finishing tool is hardly inserted into the pipe deeply, being impossible to finish. Therefore, a new technology has been considered to finish inside of a slender ceramic pipe by a simple technique. In this experimental, Magnetic Abrasive Machining is applied for the inner surface of silicon nitride fine ceramic pipe using ferromagnetic particles mixed with chromium-oxide powder. It is shown the initial roughness of 2.6㎛ Ry(0.42㎛ Ra) in the inside surface can be precisely finished to the roughness of 0.1㎛ Ry(0.01㎛ Ra). This paper discusses the outline of the processing by the application of magnetic abrasive machining and a few finishing characteristics.
