Vibratory burnishing processes produce smoothly finished surfaces on metal works by the relative motion between the work and the hardened steel tools in vibratory burnishing equipment. This process has the advantage of increasing the fatigue strength of the work surface by the tools' impingement on the work. As this process is a mass finishing process, it is difficult to achieve the precise control of the processing force as well as the tools' action on the work. This study proposes a new magnetic field assisted burnishing process using magnetically controlled motion of the tools and work. This paper presents the processing principle and a developed burnishing machine. The experiments, involved the burnishing of stainless steel and aluminum alloy bars, show the feasibility of process to achieve smoothly finished surface, work hardening, and the impartment of the residual compressive stress on the work surfaces.
