As with its wire wound brother, all types of spring format, such as
compression, extension, torsion, lateral translation and lateral bending
are available in the machined format. Machined springs can provide very
precise linear deflection rates as most residual stresses are eliminated.
In a wire wound spring, internal stresses may be present and these have
to be overcome before deflection occurs. Additionally, machined springs
can be offered in multiple start configurations - essentially intertwined
continuous coil elements with several independent helixes in the same
cylindrical plane. Another advantage of machined springs is the
possibility of forming an 'assembly' as a single part. The wound spring
assembly on the left in this illustration, for example, was made from
four separate pieces, whereas the machined replacement on the right is
just one part. You can obtain machined springs from Abssac, who
recommends them for critical or high duty cycle applications
