For one Connecticut manufacturer of close-tolerance, precision-stamped and coiled metal parts, an eight-year journey to provide its customers with higher precision parts from progressive tools has reached a happy ending. In-house CNC machining has allowed it to stamp parts at a very low cost, and then machine crucial features into them.

In just a few short years, the company jumped from one used machining center to 12 new centers, including some highly automated centers with the potential to reduce cut times by nearly one-third, while maintaining tolerance and finish requirements.

What differentiates the Farmington, Connecticut-based Connecticut Spring & Stamping (CSS)’s approach from traditional machining suppliers is that stamping and then machining results in a much lower-cost part than a fully machined part. Also noteworthy is that, by doing all of the processing in house, CSS controls all aspects of the part, from prototyping and development to final production. Designing and building both the progressive tooling for the stamping and the fixtures required for the machining process helps CSS meet the quality requirements of its customers, especially those in the medical device industry.
