Abstract

Lead, especially micro lead, on ground shaft sealing surfaces has been an ongoing issue in sealing technology for many years. Now that suitable lead measuring methods have finally been developed, the scientific focus has shifted from the measurement of lead and its influence on the sealing function to the formation of lead. Experimental investigations have been carried out to analyse the influence of the process parameters on the formation of micro lead during external cylindrical plunge grinding. The results show that micro lead occurs using industrial common parameters. The influence of the grinding tool specification, the dressing and the grinding parameters on the micro lead structures are described and discussed.
