<p>An internal grinding machine comprising support means (7) for holding a workpiece (1); a spindle (2) having a grinding wheel portion (3) arranged to carry a grinding wheel (4); bearing means (11-13) for rotatably mounting the spindle (2); driving means (14,50) for rotating the spindle (2); and feeding means (8a,22,23) for effecting relative movement between the support means (7) and the spindle (2) to enable a grinding wheel (4) carried by the grinding wheel portion (3) to effect grinding of a bore or internal recess (a) in a workpiece (1) carried by the support means (7) characterised by sensor means (15-17) for detecting the position of the spindle (2) relative to the bearing means (11-13); and control means (33), controlled by the sensor means (15-17), for controlling the operation of the bearing means (11-13) so as, when necessary, to adjust the position of the axis of the spindle (2) so that the bore or internal recess (a) can be ground to a substantially cylindrical form.</p> |
