易填塞材料因其材料性質，容易使其切屑因高溫而填塞，導致砂輪性能降低。因此必須修整砂輪才能回復砂輪性能，但頻繁的修整會導致砂輪的消耗增加並增加加工時間導致加工成本的增加。
3M公司新式磨料技術──Cubitron™ II，其重點為砂輪是由大小均一的三角形氧化鋁陶瓷磨粒所組成，較以往不規則磨粒不同，使得其磨削機制較傳統磨料有明顯的不同，相較以往其有較良好的磨削過程以及自銳現象。對磨削加工而言，它有可能帶來更高的材料移除率並降低磨削所產生的熱，並在此同時維持良好的工件表面品質。
本文希望運用Cubitron™ II 砂輪相較於以往氧化鋁砂輪磨削機制的不同，使其可能有提升材料移除量、降低磨削力、磨削溫度與工件表面粗糙度等的特性，並用切屑構型跟磨削性能的數據判斷Cubitron™ II 砂輪是否有助於提升對於易填塞材料的加工效率並延長砂輪使用壽命。

Easy-loading material is prone to load in high temperature while grinding ,which makes grinding wheels’ performance decreases. Thus we must repair the grinding wheel in order to recover its property. However frequent repairing will increase the cost.
With the latest tech Cubitron™ II from 3M, grinding wheels are made up of uniformly sized triangles of ceramic aluminum oxide in uniform size. Compared with the irregular size, the uniform size have great grinding process and great self-sharpening. For the grinding process, this tech may cause higher material removal rate, reduce the temperature while grinding and maintain the high quality of the surface.
Compared with the aluminum oxide grinding wheel,this study will apply the Cubitron™ II grinding wheels to increase the material removal rate ,and reduce the grinding force, temperature and surface roughness. Meanwhile we will use data from Chip formation and grinding performance to determine whether the Cubitron™ II will increase the processing efficiency and the lifetime of grinding wheels for the easy-loading material.
