Precision grinding of structured ceramic molds by diamond wheel trued with alloy metal

Needs of micro structured components and its molds/dies are increasing in a solar cell system, an infrared night view and micro medical devices. In order to improve the accuracy of the structured molds/dies made of tungsten carbide, a new truing method of the diamond grinding wheel by alloy metals was proposed and the performance of the proposed truing method was evaluated. In the grinding test, Fresnel molds of tungsten carbide were ground by using the diamond wheel trued with the alloy metal. From the experiments it was clear that the form accuracy and surface roughness of the ground molds were improved.
