ATLANTIC :: Grinding processes

Grinding processes. 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 ...
