Can a thread grinder grind copper?

Yes The grinder can grind a variety of materials, including copper and aluminum. Because grinders are made for grinding a variety of materials, grinders in many factories do not grind all iron pieces. Both copper and aluminum are ground. However, if the grinder really wants to grind copper or aluminum, the grinding wheel must be replaced by a diamond grinding wheel. The commonly used white diamond grinding wheel is suitable for grinding hardware, while copper and aluminum are soft, so diamond grinding wheel must be used.
