本文使用研磨技術以克服陶瓷硬脆材料之難加工特性,利用鑽石砂輪,配合高速氣動主軸進行高速磨削,砂輪粒度為25μm與5μm,主軸轉速10,000rpm、40,000rpm、70,000rpm。藉由更改原有的磨削方式,使研磨在相同條件下有更加優異的結果,利用新的磨削方式,更改設定參數的加工時間,本文並比較與既有方式的差異性。 本研究利用表面輪廓儀(Surface Profilometer)對加工結果進行觀察,從加工數據顯示,材料在新式與舊式的加工方式下,新式加工方式在各樣參數設定下表現結果都較優異;轉速提高時表面粗糙度值都有下降趨勢;但在磨削方式上,新的加工方式時間較長,表面粗糙度表現在各加工參數下都較佳,且是舊式的兩倍以上。在轉速10,000rpm、 40,000rpm、70,000rpm下結果都顯示,新加工方式雖然加工的時程拉長20-25%,但材料表面粗糙度值降低50%以上。
This thesis uses grinding technology to conquer the machining characteristics of ceramic brittle materials which is hard to process. We use the diamond wheel with high speed pneumatic spindle to grind in high speed. Granularity of diamond is 25μm or 5μm, that the rotational speed of spindle is 10,000rpm、40,000rpm、70,000rpm. By modifying the original grinding way, we can get better result in the same conditions of grinding. This thesis compare the difference between the new and old grinding processes under the same rotating speed and feed rate. In this thesis, we use surface profilometer to observe the process result. According to the process data, the new type of process is better than the old type in every setting. While raising the rotational speed, the surface roughness is increased. According to the grinding method, the new type of process need more time but the behavior of surface roughness is much better than the old type of process in every process. It shows that, in 10,000rpm、 40,000rpm、70,000rpm, the new process will increases the process time about 20-25% and smoothen the surface roughness more than 50%.
