The new method of deformative strengthening of holes using combined static and impulse loading is presented. Partial replacement of static load, used in classical burnishing, by impact impulses allows decreasing energy intensity of strengthening process and expanding the technological capabilities of the method. The method allows strengthening of small diameter and long length holes. The high depth and degree of strengthening can be obtained; the surface roughness can be decreased. The experimental complex for research of static-impulse parameters of deformative drawing of holes of machine parts, which allows determining the influence of energy parameters of the process taking into account stiffness of technological system on roughness, depth and degree of strengthening of holes surfaces, is developed.
