The grinding wheel is the actual tool of the CNC grinding machine. Grinding wheels are rotationally symmetric tools whose abrasive grits are held together by means of a bond. The sharp edges of the abrasive grits remove material by means of cutting when they come into contact with the part to be ground. Grinding wheels are very complex tools.

HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore ...

rolls on two support rollers, and the shell moves circumferentially relative to the tire ID. Any relative misalignment of these interactive components results in mechanical instability. Consider the rolling motion of the tire on a support roller. If the tire axis is parallel to the roller axis, both components roll in the same direction.

Some recent grinding installations in Australia have demonstrated potential for ultra-fine grinding with acceptable power consumption (Johnson, 1998). A combination of high-pressure rolls and ultra-fine grinding devices could potentially save energy in the production of ultra-fine particles because they create micro-cracks during the crushing step.
