Description

Although a rather voluminous paper on drawing fines appeared in Wire Journal International several years ago, the complexity of this topic and numerous related variables indicated the necessity of a follow-up. The present article covers a number of new details and variables related to the formation and analysis of fines. Included herein are discussions and some practical solutions concerning the analysis of fines at a die pass, which includes proper sampling as well as testing of water based, oils, and solid lubricants, the incoming and exiting wires, and the dies and die holders.
