Machined Springs

Machined springs can provide linear-deflection rates. There are no internal stresses to overcome before deflection occurs, which can be the case with traditional springs.

All machinedspringcoils deflect under load. One advantage of machined springs with two or more integral coils is that there are redundant elastic elements in the event of failure, and a failed element (coil) will be physically trapped by one or more other coils. In many cases a broken spring will continue to function. There is no tendency for machined springs to squirm when deflected and no restraint is required to resolve the free moment. Double and multiple starts (coils) make loading points irrelevant on the radius of the spring and also increase parallelism accuracy.
