An internal finishing process applying Magnetic Abrasive Finishing (MAF) was proposed to produce smooth inner surfaces of tubes at a high rate. Since this process has used the tube rotation system, it is considered applicably only to tubes which are rotatable at high speed. To extend the area of the internal finishing process applying MAF, the development of the stainless tube(STS 304) rotation system using WA-Fe-B-F abrasive grain has been tried. By applying the stainless tube(STS 304) rotation system and the magnet ic abrasive grain method, the effects on the surface roughness using WA-Fe-B-F abrasive grain are as follows:
1) The magnet abrasive finishing minimized influence due to external force because non-contact finishing
2) The profile of surface roughness decreased very smooth surface in magnet flux density 1600G due to abrasive speed.
3) The profile of surface roughness by finishing time the more decreased in abrasive grain 140㎛.
4) The friction force and finishing force is usually depended upon magnet brush behavior due to flux density.
