The next time you require a spring in a critical or high duty cycle environment, the machined spring from may be the answer to your design problems. The product is machined to meet exact customer size and performance requirement. Machined springs are a formidable package and for those engineers familiar with the traditional wound spring format we are offering a new way of looking at both performance and attachment. As the name suggests, we supply a spring that is machined from one piece of material. With machined springs all the usual types of spring format are available. The most demanding extension, compression, torsion, and lateral bending and translation spring applications can benefit from machined springs because of their superior function and inherent versatility.
We often ask.....Do you know what a machined spring is ?
Whilst we all agree that traditional wire wound springs have numerous bonifide applications, the very nature of how they are manufactured can limit their reliability and performance in the more demanding or high duty cycle spring applications. Machined springs benefit overall system designs through enhanced functionality, increased precision and cost reduction as a result of true engineering expertise. Time and time again we have reduced the burden overhead within mechanical systems with the machined spring product.
Uniquely, we can amalgamate parts of the total spring assembly into the single part ...
Once the working dynamics of the spring are calculated and agreed, we can then look at the method of attachment. In many cases the machined spring incorporates other parts of the working mechanism into the single part, such as flanges, gears, splines etc, making the final item more reliable. The choice of end attachment is really up to your imagination. !
The advantages of the machined spring products
are numerous having proven itself in medical, aerospace, semiconductor and motor-sport industries to name a few. Wherever a wound spring is not able to meet your performance criteria or a new spring design requires ultimate accuracy and repeatability, the machined spring is the ideal partner. If you require further technical information, please do not hesitate to contact our sales engineers who will be more than happy to help you with your selection.

When considering the dynamics of the machined spring the we look at the 6 possible Cartesian co-ordinates, those being X,Y,Z and then the ROTX, ROTY & ROTZ (please refer to illustration below)
A wound spring tries to deliver all 6 axis potentials when it is asked to move. A machined spring can be a single degree of freedom system, delivering motion in only one of the possible six axis and the double start machined spring is the closest single Cartesian co-ordinate deflection part available with todays technology.
However it must not be forgotten that it is also possible to predict and deliver multi cartesian axis springs. For example, some applications have demanded an accurate mixture of compression, lateral and torsional spring rates. !
