Tool and cutter grinder

 · The electrochemical grinding process is a highly specialized method that combines surface grinding, chemistry, and fixturing, and has limited applications. OD grinding is used to shape the external surface of objects between the centers and excels at removing circular defects and restoring or creating roundness. · Before grinding, examine the power cord, extension lead, plugs, sockets and power outlet for damage. Also, ensure that the grinding disc, guard, and attachments (including handle) are secure and correctly fitted. Lastly, inspect the grinding disc for damage; never use a damaged grinding disc, and never use a disc on a surface that might damage it.The operation of this machine (in particular, the manually operated variety) requires a high level of skill. The two main skills needed are understanding of the relationship between the grinding wheel and the metal being cut and knowledge of tool geometry. The illustrated set-up ….
