Machined springs combine the elastic properties of materials, such as high-strength steels, aluminum, and titanium, with a curved helical beam for precise deflection rates for compression, extension, torsion, lateral bending and lateral translation spring functions often needed in medical equipment. Machined springs often provide more precise operation than do traditional designs.
