Recently, micro aspherical glass lenses are required for electric devices, optical devices and advanced optical fiber transmission equipments. The glass lenses are manufactured with glass molding method by using ceramics dies such as tungsten carbide and therefore molding dies are most important. The ceramics molding dies must be ground ultra-precisely with micro diamond wheel.

Sub-Micron Precision Grinding Capabilities At Camcraft. Just like clockwork. As time passes, higher demands are placed on all engine components— and to be more precise, fuel injection technology is where engine manufacturers routinely look to make bigger and better gains in efficiency and reduced emissions performance.
However, it is a difficult task to establish a comprehensive grinding force model that takes into account the brittle fracture, grinding conditions, and random distribution of the grinding wheel topography. Therefore, this study developed a new grinding force model for micro-grinding of reaction-bonded silicon carbide (RB-SiC) ceramics.
