Grinding is a process with numerous geometrically undefined cutting edges/abrasives, which are integrated in the grinding wheel. Grinding is a manufacturing technique for machining surfaces with abrasives. The rotating grinding wheel performs the cutting motion, while the feed motions are conducted by the grinding wheel or the workpiece, depending on the machine concept and grinding process.

The Grinding Process Grinding is a material removal and surface generation process used to shape and finish components made of metals and other materials. The precision and surface finish obtained through grinding can be up to ten times better than with either turning or milling. Grinding employs an abrasive product, usually a rotating wheel brought into controlled contact with a work surface ...

it is difficult to fabricate thick MEMS structures using the silicon dissolved wafer process due to the limitation of the diffusion process. The typical diffusion time is 15–20 hours for a diffusion depth of 15–20 µm. In order to supply a thick device silicon layer (>30 µm) on the glass, the conventional SOG process is widely used [9–11]. In the conventional SOG process, some shallow ...
