The diameter of the anterior and posterior of the grinding bone window in the retrosigmoid sinus-internal auditory canal approach was 21.95±2.23mm. In front of the exposure area were the internal carotid artery, the cavernous sinus, and the upper trigeminal nerve; the lower part was the connection between the facial acoustic nerve and the abducent nerve.

The paper presents the results of investigations on the effect of the depth of concurrent grinding of flat surfaces on the roughness and nano-hardness of the surface layer of C45 steel with a ferritic-pearlitic structure and average grain size of 20 μm. A significant increase in the hardness of the surface layer of the workpiece was obtained for all grinding depths.

Grinding . Mortar and pestle is the best known tool for grinding, but many tools are used for grinding, including grain mills, coffee grinders, and some more refined laboratory apparatuses including vortexers and glass homogenizers. Grinding relies on creating friction by sandwiching the sample between two hard surfaces that slide against each ...
