The analysis of a trajectory of motion of the base end of the tapered roller in difficult feed rate on finish grinding on the SXK-5A machine is given. Mathematical models of feed rate for any point of a processed surface of the tapered roller are obtained. There are formulas for calculation of feed rate of bearing roller on the operation of sphere grinding on the SXK-5A when roller is set in a cage which doesn’t have the special drive, and is clamped by two disks rotating in different sides with individual drives. Regularities of components of feed rate change are shown. With use of the obtained formulas feed rate of three types of the tapered rollers which base ends grind on the SXK-5A machine on “EBC Volzhsky” are calculated. Results of calculation are given as an example in figures without coefficient of slippage of feed rate for various points of a base end of a roller.
