External grinding machines are specialized tools used to grind the outer surface of cylindrical workpieces. These machines are crucial in industries where precision is key, such as automotive, aerospace, and heavy machinery manufacturing. By removing small amounts of material from the workpiece, they achieve the desired dimensions and surface finish.
