For production of standard straight, barrel shaped, or conical shaped pitch or closed wound springs, RK recommends the Herdon CSC Series 2 - 3 axis CNC Spring Coilers. Fast, rugged construction, easy to use, and economically priced, the CSC Series Spring Coilers are engineered to provide years of high volume, high speed production service while maintaining tight dimensional tolerances. Five models are available, covering wire sizes from .15mm (.006") to 8mm (.315").

The CSC Series software is easy to use yet surprising powerful. Most programs can be generated and refined to blueprint specifications in minutes and require only five lines of programming! First time set ups generally can be up and running in less than half the time required to set up conventional mechanical coilers, and repeat set up times are further reduced since the program is automatically saved for future reuse. The standard configuration of the CSC Coilers is two axes of CNC control - Y Axis (wire feeding) and X Axis (camshaft of cut-off, pitch, and diameter mechanism). An optional third axis CNC diameter control is also available to reduce set up times when unusual spring shapes are required.

Spring makers will also appreciate the improved diameter control slide mechanism of the CSC-16/26/50/80, which eliminates the need to change coiling attachments for coiling direction changeover (due to it’s small size, this is not required with CSC-8). The European style two point coiling system also reduces changeover times and generates significant savings in reducing tooling requirements. Grinding arbors to precise size and shape - required with conventional mechanical coilers (and some CNC coilers) - is eliminated. The option to use either ‘universal’ horizontal pitch tools or vertical pitch tools also drastically reduces the amount of tooling required in the spring makers inventory. All this means there will be no more need to waste valuable time while the spring maker grinds tooling for sample orders or hot jobs.

As with all of our machinery RK offers complete packages including all necessary tooling and wire pay-off unit so there are no hidden costs. We would be happy to configure a machinery and tooling package to suit your specific needs.

Many spring makers are reluctant to invest in new CNC machinery when they are ‘getting by’ with conventional mechanical machinery. With the Herdon CSC line of CNC spring coilers you will be surprised by how affordable CNC technology can be. In addition, besides reducing set up times the CSC spring coilers are cable of producing springs at higher production rates than conventional machinery while reducing scrap rates or eliminating scrap altogether. When all is added up, you’ll see that your investment in a CSC coiler will pay for itself the moment it hits your shop floor.
