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.

Features:
•Process coiled wire into finished bars
• 5-Die arbor. Five die adjustment allows for greater control and flexibility when working with high tensile material.
• SYNCHRO/CUT Entrance and Exit Feed Heads, Provides the tractive force required to pull high tensile material through the arbor. Precision four-roll feed heads with dual-grooved feed rolls that are belt driven by AC variable frequency drive and electric motor. Pneumatic feed roll pressure control is standard.
• Synchronized “Clutchless” Cutter. SYNCHRO/CUT Continuous straightening action with moving cut – eliminates marking, hotspot and overworked sections in wire that may result with stationary cut machines.
• Computer control with touch screen station
• Programmable Parts counter
• Arbor and Feed speed adjustments with digital feedback meters
• Programmable safety shut down timer, stops the machine if a feeding problem restricts wire and reduces scrap
• Electronic Pneumatic Feed Head pressure adjustment, accurate and repeatable
• Micro-fine length adjustments can be accomplished while in operation
• Lower temperature rise of straightened wire product
• Reduced wear, less material transfer and longer life of feed rolls
• Less sensitivity to feed roll clamping pressure and easier setup
