The preparation for the operation of disk cutting tools by means of the creation of in them a preliminary stressed state (residual stresses) is considered. Methods for the definition of the influence arising at the operation of the uneven heating of a tool body upon its stability and dynamic characteristics which allows substantiating a choice of a formed field of residual stresses at preparation are mentioned. The admissible levels of residual stresses which do not result in the flat form distortion of a disk after rolling are defined and a method for the definition of corresponding pressing forces of rolling elements in the form of spherical rollers is offered.
