When using a CNC internal grinder for internal grinding, the choice of grinding wheel is important and can be said to be crucial. Generally, it is not allowed to choose grinding wheels larger than the diameter of the workpiece hole, nor can it choose grinding wheels that exceed the length of the workpiece hole. So, the choice should be cautious, and the appropriate grinding wheel and grinding wheel shaft should be selected according to the size of the workpiece aperture.
In another scenario, when operating a CNC internal grinding machine, if the diameter of the grinding wheel is too small, it will cause a decrease in its circumferential speed, resulting in a decrease in power. If the grinding wheel shaft is too long, it will reduce power and be prone to vibration problems.
