Rowe (1967) describes experiments on four grinding machine spindles, including aerostatic, hydrostatic, and hydrodynamic spindles. Rowe and O'Donoghue (1970) consider the development and testing of diaphragm valve-controlled hydrostatic bearings. Leonard and Davies (1971) study the dynamic behavior of a four-recess hydrostatic journal bearing.

Internal grinding of inner rings, or bore grinding, involves a unique set of challenges. A relatively small wheel with few cutting edges, a large contact arc and the risk of non-rigidity in the spindle can generate excess heat and deform a workpiece or limit productivity – creating a demand for very.
