19 How to Choose Internal Grinding Wheels ? |Newdiamondtools

1.Selection of the diameter of internal grinding wheels. When the internal grinding is performed in the inner hole, and if the diameter of the grinding wheel is too large, the contact arc between the grinding wheel and the workpiece increases. It increases the grinding heat and is difficult to cool and remove the debris.
