ABSTRACT:
A centerless grinding machine comprising a grinding wheel on a rotational sleeve supported by a hydrostatic bearing means on a stationary spindle fixed to a grinding wheel table, a regulating wheel supported by a hydrostatic bearing on a spindle fixed to a regulating wheel table, and a blade for supporting a workpiece. Both wheel tables supporting the corresponding wheel are guided along a hydrodynamic sliding guide way to which a uniform pre-load is applied by hydrostatic bearings, and a servo mechanism is provided to compensate for frictional forces generated on the feed guide way, whereby it is possible to accomplish fine positioning of the corresponding wheel table and to grind the outer periphery of the workpiece with high precision and efficiency.
