铝镁合金以其质量轻、耐腐蚀等良好材料性能，广泛应用于各个领域。针对当前铝镁合金砂轮磨削加工存在的效率低、表面质量难以保证、砂轮表面易发生粘附等问题，提出采用砂带磨削技术对铝镁合金进行加工。为研究铝镁合金砂带磨削工艺规律以及在磨削过程中容易产生的粘附特性问题，运用36、60两种目数的氧化铝陶瓷、碳化硅和锆刚玉砂带进行铝镁合金磨削实验，分析不同磨削压力和砂带转速下的铝镁合金材料去除率、磨削噪声、磨削能耗和砂带材料粘附率的变化规律。结果表明：在相同磨削参数下，3种砂带中锆刚玉砂带因磨料韧性、抗冲击性、锋利程度更优，其材料去除率最高，粘附率最低，但磨削噪声和能耗更大，故在铝镁合金砂带磨削中，如果不考虑噪声和能耗的影响，可选择锆刚玉砂带以提高磨削效率；3种砂带的磨削压力达到20 N后，砂带粘附达到稳定形成阶段，磨屑堵塞磨粒间隙，使材料去除效率降低。这一结论可为铝镁合金砂带磨削压力参数的选取提供参考；在10~30 N、1 500~3 500 r/min的工艺参数范围内，磨削压力和砂带转速对材料去除率、粘附率都有很大影响，但砂带转速对磨削噪声的影响更大，磨削压力对磨削能耗的影响更大。研究结论可为提高铝镁合金砂带磨削效率与质量，降低磨削噪声与能耗提供一定参考。

Aluminium-magnesium alloy is widely used in various fields due to its good material properties such as light weight and corrosion resistance. In view of the low efficiency of aluminum grinding alloy grinding wheel, the difficult surface quality and the surface adhesion of grinding wheel, this study proposed the use of abrasive belt grinding technology for the processing of aluminium-magnesium alloys. In order to study the law of grinding process of aluminium-magnesium alloy abrasive belt as well as the problem of adhesion characteristics easily produced in the grinding process, the study used 36, 60 two mesh alumina ceramic, silicon carbide, zirconium corundum abrasive belts to carry out experiments on aluminium-magnesium alloy grinding, and analyzed the material removal rate of aluminium-magnesium alloy, the noise of grinding, the energy consumption of grinding, and the rule of change of the abrasive belt material adherence rate under different grinding pressures and the rotational speed of abrasive belt. The results show that: under the same grinding parameters, zirconium corundum abrasive belt has the highest material removal rate and the lowest adhesion rate due to better abrasive toughness, impact resistance and sharpness, but the grinding noise and energy consumption are greater. So in aluminium-magnesium alloy abrasive belt grinding, zirconium corundum abrasive belts can be chosen to improve the grinding efficiency if the influence of noise and energy consumption is not considered. After the grinding pressure of three abrasive belts reaches 20 N, the adhesion rate of the abrasive belt reaches a stable formation stage, and the abrasive chips block the abrasive grain gap, which reduces the material removal efficiency. This conclusion can provide a reference for the selection of grinding pressure parameters for aluminium-magnesium alloy grinding belts. Within the range of process para-meters of 10~30 N and 1 500~3 500 r/min, the grinding pressure and the speed of abrasive belts have a great influence on the material removal rate and adhesion rate. However, the grinding belt speed has a greater effect on grinding noise, and the grinding pressure has a greater effect on grinding energy consumption. The conclusions of the study can provide certain reference for improving the efficiency and quality of aluminium-magnesium alloy belt grinding and reducing the grinding noise and energy consumption.
