Product Description
The machines can be equipped with measuring gage, length correction and sorting of good and bad springs according to length criteria. The system could be internal or external, depending on the model.
The axes (independent movements) are the following: wire feeding – diameter, pitch and cutting cams. As an option, on some models, it is possible to have a 3rd axis, to separate the diameter and pitch, or a 4th axis, to separate the cutting as well. The customer chooses whether the 3rd axis is the pitch or the diameter.
The pitch is horizontal or vertical, at the operator’s choice.
Some models are equipped, as an option, with a torsion spring manufacturing system, by the addition of a single coiling point, mounted on a slide whose up and down movement is controlled by a cam, itself mounted on an additional shaft.
