  • ABSTRACT: Toroidal roller burnishing is a cost effective process for finishing of metal machine elements by means of surface plastic deformation. The surface integrity of the burnished components is characterized by low roughness, high micro-hardness and beneficial compressive residual stresses. The deforming tool is toroidal roller made of tool steel. In order to study the burnishing process, a corresponding device is necessary. This paper is devoted to synthesis and development of conventional roller burnishing device, allowing easy and quickly set of the geometrical and physical parameters of the process. For this purpose a morphological analysis of existing burnishing devices using rolling contact was made. Using the differential-morphological method, a device functional scheme is justify and chosen. On this basis, a construction of the device is designed and manufactured. The device is intended for comprehensive experimental study of the toroidal roller burnishing process
