傳統樹脂砂輪使用熱固性樹脂作為結合劑，但熱固性樹脂其固化時間長，樹脂內含有機溶劑而造成環境污染，且製作成本高。而紫外光固化樹脂其固化時間短，無環境污染之問題，製作成本低，故本研究利用紫外光固化樹脂最為微小鑽石砂輪之結合劑，並利用輪磨試驗來觀察經輪磨加工後砂輪與加工件表面形貌之改變，砂輪之切削能力探討等。
    本研究首先對紫外光固化樹脂進行基本特性分析，如影響固化時間之因素及固化後之機械特性，爾後再以紫外光固化樹脂作為微小鑽石砂輪之結合劑，並進行輪磨實驗。經研究發現，紫外光固化樹脂中壓克力單體之官能基數會影響固化時間、固化後之機械特性及固化後之收縮量，且在加入鑽石磨粒後會使固化時間拉長。輪磨實驗結果得知，利用不同之結合劑配合不同之輪磨參數，其輪磨效果皆不同，若是結合劑中混合有三官能基與單官能基壓克力單體者，經輪磨加工後具有較佳的實驗結果。
    最後，以紫外光固化樹脂作為微小鑽石砂輪之結合劑並且應用於輪磨加工上是可行的，將來應用於更精密之輪磨加工其發展性與實用性是可以值得去探討與研究。

The traditional grinding wheels, being normally produced using thermosetting resin as the bonding agent, have its shortages such as long curing time, containing volatile organic content which produced environmental pollution, and high manufacturing costs. The ultra-violet curable resins, using UV-light to cure, can improve those deficiencies. In the present research ultra-violet curable resins were used as bonding agent to produce micro-diamond grinding wheels. Efforts have been made to analyze the characteristics of ultra-violet curable resins, various combinations of resins/abrasives, and the mechanical properties of cured grinding wheels. The obtained grinding wheels were subsequently used to grind silicon specimens to investigate its machinability. The results showed that the number and type of functional groups possessed by the acrylate in UV-curable resins could have profound effects on curing time, shrinkage and mechanical properties. Owing to the absorption and reflection of UV-light introduced by the abrasives, the curing time might vary depending on the amount and type of abrasives being put into the resin. It was found that better grinding results were obtained when wheel was made using the mixture of tri-functional and mono-functional groups acrylate as the bond agent. It was showed in this study that using UV-curable resins as bonding agent to produce grinding wheel was feasible and worth spending more time for further development.
