Design Features

Optimized unit costs due to an increased production output and availability ensure high efficiency
J Exceptional variety of parts, production of rings and wave
springs of the most diverse geometries and even thesmallest diameters– Cutting position can be selected based on product requirements– Programmable height and course of waves– A wave shape other than the sinusoidal shape can be
programmed
J High operating convenience with a simplified and optimized set-up and an increased machine availability– High-end control WPS 3.2 EasyWay– integrated shearing cut (SNA 16)– repeatability of all settings as exchangeable magazine canbe changed as a whole– central nut for clamping rollers– production monitoring via laser– tools made of tungsten carbide
J Innovative and modern machine design

Mechanical system:
J Reliable technology of the SNA series with more than one
decade of WAFIOS expertise in the production of rings andwave springs
J The shearing or shaping cut enable customized cut-offs, anadjustable cutting position based on the machine size and thepossibility to influence the cutting burr
J The new machine design facilitates set-up and accessibility
J The two feed roller pairs are directly driven
J Optional CNC pitch device for the production of wave springs
that feature different wave heights
J Ejection and slip control ensure an effective production
J Guide rollers can be changed by changing the entire unit. This
enables a preliminary set-up outside the machine

JT Good ergonomics and accessibility

2 WAFIOS Precision Machinery for Wire and TubeControl System:
J Programming of ring and wave spring geometries withWPS 3.2 EasyWay
J Reduction of the coiling-in compensation (the so-called “flowering effect”) by means of an all-electric coiling/pitch axis andan intelligent software control

Most Diverse Applications in the Ring andWave Spring Production:
The newly developed SNA 16, SNA 26 and SNA 36 are anintegral range of machines for the production of rings from7 – 320 mm outer diameter and wave springs from 7 – 250 mm.
This machine series has been designed in line with the requirements of the production of right-hand coiled wave springs andsingle- and/or two-turn rings, with or without crimp, made of
profiled material (rectangular cross section). It features a significantly increased output while meeting highest quality criteria.
S Geometrical programming with WPS 3.2 EasyWay

Another focus has been placed on the operation of the machines and on the optimization of set-up processes. The newWPS 3.2 EasyWay user interface and the new CNC-controlledcoiling and pitch units (reversing and freely programmable) enable a quick retooling process. Together with the intelligent software integrated in the machines, the quality of parts is increased
significantly (e.g. the “flowering effect” of the outer diameter isavoided by the coiling-in compensation (option)).
