Grinding is an abrasive machining process that uses a grinding wheel as the cutting tool.
The process is divided into two basic applications:
Precision grinding (more commonly, die grinding) with handheld tools is done to remove material from small areas or spots, cavities, or other confined spaces.
Rough grinding is effectively removing as much material (stock) as possible. Surface finish is of minor importance in this process. Removing redundant material from the cast, forged, or welded pieces can involve leveling or smoothing edges and giving the piece the required shape. It can also mean removing material to form or enlarge a cavity.
Challenges within grinding application
Grinding usually requires more process time and force in order to get rid of the right amount of the material. This makes the process physically hard for human workers.
