Lewis 16TM SYNCHRO/CUT Wire Straighten and Cut Machine

Rockford Manufacturing Group introduces our new LEWIS SYNCHRO/CUT Series of wire straighten and cut machines.

This innovative machine addresses applications where tighter control of wire diameter and reduced work hardening of the straighten and cut product are paramount for the customer’s application. Lewis Machine is well known for the “Travel-Cut” F Series machines, which have been supporting the wire industry since 1936. With over 850 machines built, these older mechanical marvels have a reputation of providing decades of robust, dependable service.

RMG recognizes the time has come for the next generation of wire straightening and cutting machines to serve this market. To address this challenge, we developed a novel moving shear machine by leveraging our years of experience with the Lewis Machine product line. The cutter is synchronized with the wire speed so there is no wire feed stoppage during the cut cycle. In addition to eliminating the swell spot during cutting, the Lewis SYNCHRO/CUT will produce cleaner cuts and less wire marking while accurately controlling the length of cut.

Standard Features
