What is a machined spring? It is a single piece of material that is precisely designed and machined to have spring characteristics. Machined springs can be engineered to provide precise performance as a compression, extension, torsion, lateral translation, or lateral bending spring. By producing rectangular coils with high aspect ratios, you can tailor the performance characteristics of a machined spring to even the most exacting application requirements. A machined spring design, or Flexure, can also be engineered with more than one starting point to solve issues common to more traditional springs, such as squareness under load and lateral force.
One key benefit of utilizing machined springs is the ability to machine attachment features into the elastic element and provide solutions not easily achievable by wire wound springs, especially in torsion applications. The integration of flanges, geometric shapes, bearing or valve seats, gears, splines, internal and external threads, and other machinable shapes are all available for the design of a machined spring. By eliminating the need for additional assembly components, a Flexure can save time in handling, provide added reliability, ensure more accurate and linear spring rates, and be held to more precise dimensions.
No company has mastered the art of machined springs like MW Industries’ Helical brand. As the creator of this concept, they have developed proprietary equipment to enable unlimited geometric versatility and have a staff of application engineers to assist in the design of machined springs for any application.
