Ends on compression springs are, typically, ground to allow the spring to set squarely on the mating surfaces, which helps increase service life. Grinding the ends increases the number of active coils and allows for lower stresses relative to applied loads. PCS has one of the most comprehensive grinding departments in the spring industry both in state-of-the-art equipment and the experience of our people.

Compression springs are, most often, coiled to a constant outside diameter. Other common forms include conical, barrel, hourglass, or various combinations as required by the application.

Among the wire cross-sections used at PCS are:

• Round wire
• Rectangular wire
• Square wire
• Special cross-section wire

Wire diameter range is from 0.004" to 0.625".

Although not limited to the materials shown, following are typical spring materials used by PCS:
Titanium Inconel Elgiloy Hastelloy		Music Wire Stainless Alloys Beryllium Copper Monel
