因應通訊手機功能日益複雜，設計日益新穎，對手機外殼(鋁合金)加工之速度與精確性 要求提高，因而對碳化鎢刀具的功能的要求也愈加嚴苛。除了碳化钨工具尺寸變小之 外，對其切削能力之要求也愈來愈嚴苛。傳統以碳化鎢(WC)燒結而成的工具(如鑚頭 (micro-drill)、铣刀(end mill))，已漸漸無法滿足快速鑽孔之需求。迫切需要開發在 微鑚頭之應膜，以提高微鑚頭之耐久性。本計畫將開發一種在碳化鎢刀具上鍍製奈米晶 鑽石薄膜之技術，以提高碳化鎢刀具之精準度及加工性能(使用壽命)。
Owing to the rapid progress in the cell phone design, the demand on the speed and accuracy of the machining of the cell phone case (the aluminum alloy) is more critical. The demand on the cutting tooling performance is also more stringent, especially the durability of cutting tool (micro-drill, end-mill). The currently used cutting tool made of sintered WC cannot fulfill the stringent demand for the machining of the aluminum alloy. Therefore, it is necessary to develop a hard coating to improve the performance of the cutting tools. In this research, we shall develop a coating technique of the ultra-nano-crystalline diamond films on WC cutting tools so as to enhance the durability of the tool in machining the aluminum alloy.
