Because the workpiece is 'wrapped around' the wheel instead of going away from it internal grinding results in a larger contact area than in external cylindrical grinding. In general, this requires softer grade wheels to be used. The geometric relationship between the workpiece and the wheel can also restrict the flow of grinding fluid into the grinding zone and care should be taken in coolant application. As a general rule the wheel diameter should be approximately 75% of the diameter of the hole being ground. To avoid 'bellmouthing' of the component, only one-third of the wheel width should be allowed to pass out of each end of the hole being ground.
