ABSTRACT:
A preload control apparatus for use in a spindle (12) of a machine tool comprises a bearing (16,17) and a plurality of springs (26a to 26d) for exerting a preload on the bearing (16, 17). Some or all of the springs (26a to 26d) are at least partly made of a shape memory alloy so that the preload on the bearing (16,17) can be adjusted with changes in temperature of the springs (26a to 26d).
