Ntw finishing method has been developed by using the fine grain Suspended in inguied (water). When the fine grain is supplied into the pipe (spcimen) rotatting on its own axis, the grain moves and causes the polishing action to the internal surface of specimen by centrifugal force of the grain.The results are as follows:1) Examination of the surface profile of the polished specimen indicated that the surface roughness is affected remarkably by the rotatting speed of specimen.2) There is good agreement between the polishing motion of grain in the pipe and the one theoretically calculated from kinematic equation of the grain. This suggested that good polishing condition can be estimated well from the theoretical culculation.

本文介绍了利用细颗粒悬浮于水中的方法进行非织造布整理的方法.将细颗粒送入沿自身轴线运动的管道（试件）中，颗粒在离心力的作用下运动并对试件内表面产生抛光作用。结果表明：1）对抛光试件表面形貌的检测表明，颗粒的抛光速度对表面粗糙度有显著影响。2）管道中颗粒的抛光运动与根据颗粒运动方程理论计算的抛光运动符合得很好。这表明理论计算可以很好地估计出良好的抛光条件。
