The original, ruggedly constructed and built to withstand years of continuous production.

CSM 20 wire forming machine


Herdon’s original line of CNC Spring Forming machinery, the CSM series features cam driven tooling slides for economy and high speed production of extension springs, torsion springs, and wire forms. Rotary quill is standard. An upgraded four axis CNC controller adds functionality to Herdon’s programming system and allows the use of additional attachments such as single and double axis servo spinners. The optional EA Second Hook Finishing Station is also available for high speed, high volume production of extension springs. The CSM series now also features a dual feedback encoder system to provide tightest wire feeding tolerances possible.
