Abstract
This article examines the generation of micro lead during cylindrical plunge grinding of sealing counterfaces for rotary shaft seals. Micro lead can cause fluid leakage through the sealing contact, impacting sealing performance. Preliminary investigations indicate that dressing parameters influence micro lead formation. This publication presents new insights into this phenomenon, aiming to enhance industrial sealing reliability by optimizing sealing counterfaces for demanding applications, such as E-powertrains with high sliding speeds and temperatures. The presented findings underscore the value of using specifically optimized grinding and dressing parameters for the manufacturing of sealing counterfaces.
期刊介绍：
The CIRP Journal of Manufacturing Science and Technology (CIRP-JMST) publishes fundamental papers on manufacturing processes, production equipment and automation, product design, manufacturing systems and production organisations up to the level of the production networks, including all the related technical, human and economic factors. Preference is given to contributions describing research results whose feasibility has been demonstrated either in a laboratory or in the industrial praxis. Case studies and review papers on specific issues in manufacturing science and technology are equally encouraged.
