Between the endless polishing belt and the material to be polished and the heat between the heat-suppressing forming belt and the pressing base, and the heat-suppressing forming belt. The frictional heat between the pressing base and the pressing base is a separate body even though the endless polishing belt and the material to be polished are in contact with each other, so that it is difficult to conduct to the endless polishing belt side, and the frictional heat applied to the endless polishing belt is The friction heat between the endless polishing belt and the material to be polished is almost the only heat.
Therefore, frictional heat that is almost half of the frictional heat applied to the conventional endless polishing belt is only applied.

摩擦熱が加わるにすぎないこととなる。Further, the rotation speed of the heat-restraining molding belt is
When the rotation speed of the endless polishing belt is set lower than that of the endless polishing belt, frictional heat between the endless polishing belt and the material to be polished is generated by the difference in speed, but the frictional heat between the heat-suppressing forming belt and the pressing substrate is correspondingly increased. The generation of frictional heat between
The frictional heat applied to the endless polishing belt is almost the same as the frictional heat generated due to the speed difference between the endless polishing belt and the heat suppression molding belt, and the frictional heat between the endless polishing belt and the material to be polished. Therefore, the frictional heat applied to the conventional endless polishing belt is less than the frictional heat applied to the conventional endless polishing belt.

By pressing and polishing the surface on which this abrasive material has been applied to the endless heat-restraining molding belt surface that is looped and rotated, the cross-sectional shape of the heat-restraining molding belt surface is processed into the material to be polished. Formed into a female shape that comes into contact with the cross-sectional shape, and then the abrasive material attached to the material to be polished is peeled off, while the surface is polished so as to surround the suspended heating suppression molding belt. The endless polishing belt is placed around the endless polishing belt, and the material to be polished, or a material having the same cross-sectional shape as this material, is laminated as an endless polishing belt and a heat suppression molding belt. Pressed against the polishing surface, the heating suppression forming belt, equal to the rotational speed of the endless abrasive belts, or polished by rotating slower than that.

る。According to the present invention constructed as described above, the endless polishing belt 2 is hung and rotated around the surface as a polishing surface, and the rotation speed of the endless polishing belt 2 is laid around the inside of the endless polishing belt 2. The endless heat-restraining molding belt 4 arranged to rotate the same or slower than that, and the material W to be polished together with the heat-restraining molding belt 4 by pressing the heat-restraining molding belt 4 from the inside to the outside. Since the endless polishing belt 2 is pressed against the endless material, or the material W to be polished is composed of the endless polishing belt 2 and the pressing base 8 which is pressed via the heat suppression molding belt 4, as described in the above-mentioned embodiment. In addition, when polishing the material W to be polished, when the rotation speed of the heating suppression molding belt 4 is set to be the same as the rotation speed of the endless polishing belt 2, the endless polishing belt 2 and the heating suppression molding belt 4 are separated from each other. In this case, no frictional heat is generated, and the frictional heat between the endless polishing belt 2 and the material W to be polished and the frictional heat between the heating suppressing forming belt 4 and the pressing base 8 become two. The frictional heat between the belt 4 and the pressing base 8 is a separate body although the endless polishing belt 2 and the material W to be polished are in contact with each other, so that it is difficult to be conducted to the endless polishing belt 2 side, and the endless polishing is performed. The frictional heat applied to the belt 2 is substantially only the frictional heat between the endless polishing belt 2 and the material W to be polished. Therefore, only about half of the friction heat applied to the conventional endless polishing belt 2 is applied.

加わる摩擦熱よりも少ない摩擦熱が加わるにすぎないこ
ととなる。When the rotation speed of the heating suppression molding belt 4 is set lower than that of the endless polishing belt 2,
The frictional heat between the endless polishing belt 2 and the material W to be polished is generated by the difference in speed, but the frictional heat between the heating suppression molding belt 4 and the pressing base 8 is also reduced accordingly. After all, the frictional heat applied to the endless polishing belt 2 is almost the same as the frictional heat generated due to the speed difference between the endless polishing belt 2 and the heat suppression forming belt 4 and between the endless polishing belt 2 and the material W to be polished. It becomes the friction heat of. Therefore, the friction heat applied to the conventional endless polishing belt is less than the friction heat applied to the conventional endless polishing belt.

図ることができる。As a result, the frictional heat applied to the endless polishing belt 2 is extremely reduced as compared with the conventional polishing apparatus having the endless polishing belt, and the life of the endless polishing belt 2 can be greatly extended, and as a result, the endless polishing belt 2 can be extended. The number of times the polishing belt 2 is replaced is reduced, the work efficiency is improved, and the amount of the endless polishing belt 2 used is reduced, so that the cost can be reduced.

Incidentally, the cross-sectional shape of the surface of the heat-suppressing molding belt 4 is obtained by pressing the surface to which the abrasive material 10 is stuck onto the surface of the endless heat-suppressing molding belt 4 which is looped and rotated and has an appropriate thickness. Is formed into a female shape that comes into contact with the processed cross-sectional shape of the material to be polished W, and then the polishing material 10 attached to the material to be polished W is peeled off, while, on the other hand, the suspended heating suppression molding is performed. The endless polishing belt 2 whose surface is a polishing surface is arranged so as to surround the belt 4 so as to circulate and rotate, and the material W to be polished, or the material W having the same cross-sectional shape as this material, is supplied to the endless polishing belt. 2 and heat suppression molding Pressed against the polishing surface of the endless abrasive belt 2 as two ply belt 4, heating suppression forming belt 4
Is rotated at a speed equal to or slower than the rotation speed of the endless polishing belt 2 to polish the material W to be polished.
When pressed against, the endless polishing belt 2 is bent according to the cross-sectional shape of the heat suppression molding belt 4, and the entire surface of the material W to be polished can be polished. Therefore, unlike the conventional one in which only the most projecting surface is polished, even the material W to be polished having a curved cross section or other complicated unevenness can be entirely polished. The application can be greatly expanded.
