本研究探讨以减少稀有材料之消耗及压缩精密加工之总生产时间为目的之切削工具在机重磨。为了使修磨过程在机床上自动进行，必须使修磨过程快速，设备简单。因此，传统的磨削或PVD涂层方法已不能满足要求。电沉积复合镀层是满足这一要求的方法之一。硬质合金刀具上的Ni-P-SiC复合涂层具有切削钢的能力。然后用H_2SO_4电解液电解腐蚀，以20μm/min或更快的速度去除硬质合金表面的Ni-P-SiC，硬质合金表面形成钝化层，氧化反应自行停止。使用这些涂层和剥离方法，重新锐化过程只需5分钟。
This study deals with on-machine resharpening of cutting tools for the purpose of reducing the consumption of scarce materials and suppressing the total production time on precision machining. To make the resharpening processes on machine automatically, the processes must he fast and its apparatus must be simple. So the conventional methods like grinding or PVD coating can't meet the requirements. Electrodeposition of composite coating is one of the methods which meet the requirements. Ni-P-SiC composite coating layer on cemented carbide tool was able to cut steel. Then, by electrolytic etching with H2SO4 electrolyte, Ni-P-SiC on cemented carbide is removed at the rate of 20μm/min or faster and the oxidative reaction stops by itself result from that cemented carbide forms passive state layer. Using these coating and stripping methods, resharpening process takes within only 5 minutes.
