摘　　要： 砂带磨削在硬脆材料加工中具有优良的性能。本文比较了砂带磨削常用的两种方式 ,并研究了恒压力压磨板砂带磨削中各影响因素 ,如法向压力、磨料种类及粒度等对花岗岩、辉绿岩、大理岩和瓷质砖这四种常用硬脆材料磨削效果的影响。试验结果表明 :采用恒压力磨削方式、较大法向压力或速度、选择较粗粒度砂带可明显提高材料切除率 ;对于硬度较低的大理岩 ,采用砂带磨削可获得高切除率。 Belt grinding shows excellent characteristics in machining hard and brittle materials. In this paper,two common grinding methods in platen belt grinding were compared. Some technical elements such as normal pressure,abrasives and their grit size which influence the grinding process when grinding four kinds of hard brittle materials (granite,diabase,marble and ceramic tile) were analyzed. The results show that higher material removal rate can be obtained with constant pressure,higher normal pressure,higher belt speed and coaser abrasivebelt. The results also indicate that effective belt grinding of soft marble with high removal rate can be achieved.
