Compression Spring Grinding

Compression spring ends often are ground to increase operational life and to allow the spring to sit squarely on the load-bearing surface. Grinding of compression springs also increases the number of active coils and the wire diameter available in a given volume of space, which can result in higher loads or lower stresses. As a modern compression springs manufacturer, our facilities operate with a wide variety of equipment - from hand-operated grinding tools to automatic, high-speed vertical spindle disc grinders.

Design of Compression Springs

Many issues related to the design of compression springs should be considered, as these relate directly to the spring's performance. Compression spring manufacturing tolerance requirements, squareness of ends, deflection and the slenderness ratio often are overlooked in the design process. Newcomb's sales and engineering staff will gladly review your compression spring specifications. We can offer design assistance and recommend the best options to control costs and make sure the spring functions to fit your needs. View our Compression Spring Gallery.
