一、概述砂带磨削的砂带是由橡胶接触轮弹性体支撑着,因而可以安全、迅速地从重负荷磨削到精磨这一范围内进行磨削加工,即作为重负荷磨削,它有很高的生产率,作为精细磨削,它又可获得很小的表面粗糙度值。用砂带磨削来降低工件表面粗糙度值时,在相同的磨削条件下,它比砂轮磨削所需要的磨削次数少,效率高,通常砂带磨削可以经济地获得Ra1.25～ First, an overview Belt grinding belt is supported by the rubber contact wheel elastomer, which can safely and quickly from heavy-duty grinding to the grinding within the scope of grinding, that is, as heavy-duty grinding, it With high productivity, as a fine grinding, it can obtain a small surface roughness value. Belt grinding to reduce the workpiece surface roughness value, under the same grinding conditions, grinding wheel grinding wheel less than the number of grinding required, high efficiency, belt grinding can usually get Ra1.25 economic ~
