This invention relates to an improved integral machined spring adapted to be used in high speed spindles employing a tool holding mechanism which rotates with the spindle. The spring assembly includes a plurality of lands and slots arranged circumferentially and in tiers and includes a top and bottom face. The axial width dimension of the slots adjacent to the end faces is less than the axial dimension of the slots between the end faces in order to distribute the stresses more uniformly. The lands form a plurality of circumferentially arranged lobes whose radial dimension is greater than the portion between the lobes, again to distribute the stresses more uniformly. Various forms of the invention are described including a spindle assembly having a non-rotating actuating rod.
