摘要

摘要: 分析了砂带磨料种类、工件材料特性及磨削用量的不同对磨削加工效率和砂带磨损的影响,采用2种不同磨料的砂带分别对3种材料进行了工艺试验,对材料去除量和砂带磨损量进行了测量,揭示了砂带的磨损机理.研究表明:钛合金可磨削性较差,304不锈钢的可磨削性比钛合金好,45号圆钢最易于磨削;增加砂带线速度可在一定程度上提高材料去除率和磨耗比;陶瓷磨料比氧化铝磨料磨耗比大,因此磨削时可选择陶瓷砂带进行大余量加工;随着硬度比的增加,磨耗比呈现出先增大后减小的趋势,因此磨削时可根据磨削要求选择合适硬度磨粒的砂带进行磨削.

Abstract: The effect of abrasive belt types,workpiece material properties and different grinding parameters to grinding efficiency and different effects of abrasive wear was analyzed. The process test used two different abrasive belt respectively for grinding three different materials,the amount of material removal and belt wear were measured,the wear mechanisms were revealed. The results shows that the grindability of titanium alloy is low,that of 304 stainless steel is better than that of titanium alloy,that of 45 steel is the most than that of titanium alloy. To increase the belt speed can increase the material removal rate and the wear ratio to some extent. The abrasive grinding ratio of ceramic abrasive is higher than that of alumina oxide,therefore the ceramic abrasive belt can be chosen for large grinding allowance. With the increasing of hardness ratio,the abrasion ratio decreases after an increas,then the abrasive belt can be chosen according to the hardness of abrasive belt.
