In this paper deals with behavior of the magnetic abrasive using Ba-Ferrite on polishing characteristics in a new internal finishing of STS304 pipe applying magnetic abrasive polishing. The magnetic abrasive using Ba-Ferrite grain WA used to resin bond fabricated low temperature. And Ba-Ferrite of magnetic abrasive powder fabricated that Ba-Ferrite was crused into 200 mesh. The previous research have made an experiment in the static state the movement of magnetic abrasive grain is nevertheless in the dynamic state. In this paper, We could have investigated into the changes of the movement of magnetic abrasive grain. In reference to this result, we could have made the experiment which is set under the condition of the magnetic flux density, polishing velocity according to the form of magnetic brush.

최근 반도체 및 식품, 의료기기를 비롯한 기간산업 분야의 고도화에 따라 사용되는 부품의 정밀도뿐만 아니라 청정도를 동시에 요구하는 추세이다. 따라서 기존의 기계적 가공방법으로는 공작물 표면에 미소한 가공흔적이 남게되어 표면의 요철부분에 칩(chip)등의 불순물이 잔재할 우려가 있으며, 또한 요철 부분에 미생물이 번식할 경우 청정도가 떨어져 산업위생상의 문제점이 발생하게된다.(중략)

산업이 고도화됨에 따라 각종 기계·기구에 사용되는 부품의 고정도가 요구되면서 기존에 공구와 가공물이 직접 접촉하면서 절삭하는 가공방법으로는 절삭력에 의한 변형과 마찰열로 인하여 고정도 가공을 실현하는데 많은 어려움이 생기게 되었다 이러한 절삭가공법 중 연삭가공은 주로 가공물의 마무리에 이용되는 가공법으로서, 비교적 정밀하고 양호한 표면의 품위가 요구되어지는 부품에 사용되어왔다.(중략)

The performance of magnetic abrasive finishing fur surface is evaluated by the characteristic curve. The characteristic curve is generated by experiment in surface finishing. For experiment, new magnetic inductor is designed and manufactured. 15 kinds of powders are provided to find the relationship between powder characteristic and finishing performance. As powder, Fe-TiC. Polymer-TiC and Fe-NbC are used with different size. The size of abrasives and location are also important factor for the performance. From characteristic curve, two index are obtained, which specify the initial finishing performance and endurance of finishing performance. It is proved that the performance index can be applied to select proper powder for efficient deburring. It is shown that the characteristic curve can be used as good tools for evaluating powder performance in surface finishing and deburring.

In this paper we deal with behavior of the magnetic abrasive using Ba-Ferrite on polishing characteristics in a new internal finishing of STS304 pipe applying magnetic abrasive polishing. The magnetic abrasive using Ba-Ferrite grain WA was used to resin bond fabricated at low temperature. And Ba-Ferrite of magnetic abrasive powder was crused into 200 mesh. The previous research made an experiment in the static and the dynamic state on the movement of magnetic abrasive grain. In this paper. We investigated into the changes of the movement of magnetic abrasive grain. In reference to this result. we have made the experiment which is set under the condition of the magnetic flux density. polishing velocity according to the form of magnetic brush.

The magnetic polishing is the useful method to finish using magnetic power of magnet. This method is one of precision polishing techniques and has an aim of the clean. technology using for the pure of gas and inside of the sanitary pipe for transportation. The magnetic abrasive polishing method is not so common for machine that it is not spreaded widely. There are rarely researcher in this field because of non-effectiveness of magnetic abrasive. In this paper. We could have investigated into the changes of the movement of magnetic abrasive grain. In reference to this result, we could have made the experiment which is set under the condition of the magnetic flux density, polishing velocity according to the form of magnetic brush.
