roman\';mso-hansi-font-family:\'times new roman\'\">砂带磨削是一种弹性磨削，因而砂带磨削是一种具有磨削、研磨、抛光多种作用的复合加工工艺。</span><span lang=\"EN-US\"> <br />②</span><span style=\"font-family:宋体;mso-ascii-font-family:\'times new roman\';mso-hansi-font-family:\'times new roman\'\">砂带上的磨粒比砂轮磨粒具有更强的切削能力，所以砂带磨削的效率非常高。</span><span lang=\"EN-US\"> <br />③</span><span style=\"font-family:宋体;mso-ascii-font-family:\'times new roman\';mso-hansi-font-family:\'times new roman\'\">磨削速度稳定，由于接触轮极不磨损，砂带可运动可保持恒速，而不会象砂轮那样越磨直径越小速度越慢。</span><span lang=\"EN-US\"> <br />④</span><span style=\"font-family:宋体;mso-ascii-font-family:\'times new roman\';mso-hansi-font-family:\'times new roman\'\">砂带磨削精度高。由于砂带制作质量和砂带磨床生产水平的提高，砂带磨削早已跨入精密和超精密加工行列。</span><span lang=\"EN-US\"> <br />⑤</span><span style=\"font-family:宋体;mso-ascii-font-family:\'times new roman\';mso-hansi-font-family:\'times new roman\'\">砂带磨削成本低。这主要表现在：</span><span lang=\"EN-US\"> <br /></span><span style=\"font-family:宋体;mso-ascii-font-family:\'times new roman\';mso-hansi-font-family:\'times new roman\'\"> </span><span lang=\"EN-US\">(1)</span><span style=\"font-family:宋体;mso-ascii-font-family:\'times new roman\';mso-hansi-font-family:\'times new roman\'\">与砂轮磨床相比，砂带磨床结构简单，传动链短。这主要是因为砂带质量轻，磨削力小，磨削过程中震动小，对机床的刚性及强度要求都远低于砂轮磨床。</span><span lang=\"EN-US\"> <br /></span><span style=\"font-family:宋体;mso-ascii-font-family:\'times new roman\';mso-hansi-font-family:\'times new roman\'\"> </span><span lang=\"EN-US\">(2)</span><span style=\"font-family:宋体;mso-ascii-font-family:\'times new roman\';mso-hansi-font-family:\'times new roman\'\">砂带磨削操作简便，辅助时间少。不论是手动还是机动砂带磨削，其操作都非常简便。从更换调整砂带到被加工工件的装夹，这一切都可以在很短的时间内完成。</span><span lang=\"EN-US\"> <br /></span><span style=\"font-family:宋体;mso-ascii-font-family:\'times new roman\';mso-hansi-font-family:\'times new roman\'\"> </span><span lang=\"EN-US\">(3)</span><span style=\"font-family:宋体;mso-ascii-font-family:\'times new roman\';mso-hansi-font-family:\'times new roman\'\">砂带磨削比大，机床功率利用率高，切削效率高。</span> <span style=\"font-family:宋体;mso-ascii-font-family:\'times

roman\';mso-hansi-font-family:\'times new roman\'\">砂带磨削安全可靠，噪音和粉尘小，且易于控制，环境效益好。由于砂带本身质量很轻，即使断裂也不会有伤人的危险。砂带磨削不象砂轮那样脱砂严重，特别是干磨时，磨屑构成主要是被加工工件的材料，很容易回收和控制粉尘。由于采用橡胶接触轮，砂带磨削不会象砂轮那样形成对工件的刚性冲击，故加工噪音很小。</span><span lang=\"EN-US\"> <br />⑦
