Due to the increase of product complexity, 5 axes machining centers are becoming more and more important. Rotary tables are usually chosen for the 4th and 5th axis. Additional hydraulic or pneumatic mounting clamps are often needed on these tables. The feeding of the required media is realized by a so-called rotary manifold. For this application, commonly several rotary seals are used to seal the transmitted media. Different sealing materials, based on the carrier polymer PTFE, have been examined during this research. In tribological model tests, friction and wear characteristics have been investigated during an oscillating movement under dry run conditions and equal load spectrums (surface pressure). The counter running surfaces were specific textured as a result of various machining processes to research the effects of possible micro-and macroscopic patterning on the sealing system. The tribological behavior of the analyzed combinations and the topography of the counter surfaces have been evaluated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
