The study deals with the development of a diamond burnishing tool with a hydraulic control system for discontinuous workpiece surface finishing. Burnishing can be regarded as an alternative surface finishing technology. However, applying a commercial burnishing tool to a discontinuous surface is almost impossible owing to its configuration. We developed a hydrostatic burnishing tooling system and demonstrated the capability of the system developed. To apply burnishing to an interrupted surface, we tried to develop a hydrostatic burnishing tooling system. The system developed permits a minimum displacement of the pushed depth as well as in-process burnishing force monitoring. Some experimental results demonstrated the capability of the hydraulic burnishing tool to be applied to an interrupted surface. Also we discussed in this report is the relationship between compression depth and surface texture, determined by comparing the hydraulic burnishing tool developed with a commercial one.
