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.

In this paper, we have describes about the relationships between a core gap and a feeding velocity, an amplitude and the core gap by the exciting force, the parts movement and a bowl materials, and the feeding velocity and the weight of the parts in the parts feeder. The main results as compared with the stainless and the aluminum materials are as follow : 1) The mean feeding velocity by bowl material shown more relative proportion in the STS304 to the exciting voltage than the C5AV. 2) In the exciting voltage, the response time for the aluminum material is slow, but the stainless is sensibility. 3) An exciting voltage is rised by an increase of the weight, but an amplitude has been in the range between 23μm through 40μm.

The mechanism for cutting epoxy resins specimens, which were specially provided, was experimentally investigated to obtain a fine surface finish. The specimens were cut the three-dimensional under dry conditions using a lathe. The relationship between the topography of the cut surface due to the change rate of temperature of the cutting condition using sintered carbides (P20, K10, KT150) was investigated. The main results obtained are as follows : 1) The profile of surface roughness were regulated K10 but irregulate P20, KT150. 2) The surface roughness value decreased K10 rather than P20, KT150. 3) The cutting resistance increased thrust force rather than cutting force due to the visco-elastic material of epoxy resins.

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 uses the tube rotation system, it has been considered applicable only to tubes which are rotatable at high speeds. Here development of the stainless tube(STS 304) rotation system to extend the scope of the application of the internal finishing process applying MAF was made. By the stainless tube(STS 304) rotation system, the abrasive magnetically attracted by the poles is rotated along the inner surface of the tube by magnetic force together with fixed poles, finishing the inner surface of the tube. The main results obtained 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 good in 11.4 m/min range because abrasive size and speed, 3) The profile of surface roughness by flux density decreased in finishing speed 28m/min, 4) The profile of surface roughness by feed rate decreased in 0.16 ㎜/rev and 0.18㎜/rev.
