TL;DR: In this paper, a tool bar is matched with a bush, which is made of polytetrafluoroethylene material or engineering plastics; the bush is provided with a blind hole in close fit with a steel ball.
Abstract: The invention discloses a roller burnishing tool, which comprises a tool bar. A groove matched with a bush is formed in a surface of one end of the tool bar; the bush is provided with a blind hole in close fit with a steel ball; and a portion, exposed from an orifice of the bush, of the steel ball is less than 1/2 of a diameter of the steel ball. The bush is made of a polytetrafluoroethylene material or engineering plastics. The roller burnishing tool has the remarkable advantage of low cost because of satisfaction of a finish requirement without additional rolling equipment.

TL;DR: In this article, numerical analysis of the burnishing process of hollow steel tubes is carried out numerically using finite element method (FEM) for the calculations were used commercial software Forge.
Abstract: This paper presents numerical research of burnishing process of hollow steel tubes. The internal surfaces of the tubular elements are treated, among others, by burnishing process. The type of force can be divided into static and dynamic burnishing. The kinematics can be divided into sliding and roller burnishing. Occurrence of moving parts in direct contact with the material qualifies for the group process of burnishing rolling. The sliding burnishing design element property is part of the work surface burnished permanently attached to the handle. Theoretical analysis of the burnishing is carried out numerically. For the calculations were used commercial software Forge based on the finite element method. After burnishing modeling was found intentionally controlled state of stress and strain in the tubular elements to ensure the intended technological quality.

TL;DR: In the second CIRP group (II) some hybrid processes with controlled application of their individual mechanisms are selected (Sect. 1.3), which cover two subtractive and transformative processes (such as grind-hardening or sequential cutting and sliding/roller burnishing) as discussed by the authors.
Abstract: In the second CIRP group (II) some hybrid processes with controlled application of their individual mechanisms are selected (Sect. 1.3). They cover two subtractive and transformative processes (as for instance grind-hardening or sequential cutting and sliding/roller burnishing) or two transformative processes (as for instance cryogenic deep rolling when the machining zone is cryogenically cooled by CO2 snow).
TL;DR: In this paper, a slip-line field and corresponding ve- locity field are modified for the rolling of the rigid-plastic half-space given by Collins, which is responsible for a peeling and cracking of surface layers during the burnishing process.
Abstract: Micrographs of metal surface layers after the roller burnishing process show that while about 90% of surface 1ayer thickness is displaced forwards of a roller motion, a thin contact zone undergoes a backward displacement. This seizing effect is caused by a softening of the contact zone due to overheating of the material, during high speed rolling, or due to the plastic strain cumu- lation in the layer after multiple rolling repetition. The effect is responsible for a peeling and cracking of surface layers during the burnishing process. The plastic analysis of the process taking into account the above effect is presented in the paper. The proposed slip-line field and corresponding ve- locity field are modification of the simplified solution for the rolling of the rigid-plastic half-space given by Collins.
