Springs are fascinating mechanical components that store and release energy, finding applications in a wide range of industries. From simple devices like retractable pens to complex systems such as vehicle suspensions, springs come in various forms to meet specific requirements. This article aims to delve into the different types of springs and explore their production methods and diverse uses.

1. Compression Springs:

Compression springs are one of the most common types and work by compressing under an applied load. Their coil shape provides resistance when compressed and returns to its original form when the force is removed. To produce compression springs efficiently, CNC (Computer Numerical Control) machining techniques can be employed. This process involves programming computer software to control precise movements of cutting tools, resulting in accurate dimensions and smooth finishes. With CNC machining, manufacturers can easily customize compression springs based on desired characteristics such as material, wire thickness, coil diameter, and active coils. These versatile springs find applications in automotive suspension systems, mattresses, medical devices, and many more.

2. Extension Springs:

Designed to stretch under tension, extension springs possess hooks or loops at each end to connect with other components. They exert force when extended and return to their original position once the load decreases. Producing extension springs typically involves using CNC coiling machines, which accurately craft the required shape from a variety of materials such as steel, stainless steel, and alloy. Industries ranging from aerospace to agriculture make use of extension springs for door hinges, trampoline frames, balance scales, garage doors, and much more.

3. Torsion Springs:

Unlike compression and extension springs, torsion springs do not elongate or compress. Instead, they rely on twisting forces to store mechanical energy. Torsion springs feature tightly wound coils producing torque around a central axis, suitable for applications requiring rotational motion. CNC machining allows for precision manufacturing of torsion springs with tight tolerances to ensure effective performance. These springs are found in various products including clothespins, mouse traps, clipboards, and even garage door systems.

4. Constant Force Springs:

Constant force springs provide a consistent amount of force throughout their deflection range. Composed of a flat strip wound tightly onto a drum or mandrel, the key manufacturing processes for these springs involve CNC machining techniques such as wire forming and coiling. The result is a spring capable of delivering constant force while consuming minimal space. Key applications include tape measures, window blinds, retractable pens, and medical devices like inhalers.

5. Belleville Washers:

Belleville washers, also known as conical disc springs, resemble small cups and are used to maintain tension between connected components. These washers can be produced using CNC machining by cutting and shaping thin metal sheets into the desired shape. They find applications in bolted assemblies, energy storage devices, flanges, valves, and other machinery requiring controlled tension or movement.


Springs play an essential role in countless mechanical systems, making them invaluable across industries. Whether it's compression springs providing cushioning support or torsion springs facilitating rotational forces, each type serves specific purposes. By utilizing CNC machining methods, manufacturers can produce high-quality springs efficiently, ensuring precision and reliability. Their versatility allows for customizing springs according to specific dimensional and load-bearing requirements, enabling designers and engineers to enhance product functionality. Understanding the diverse types of springs and their production processes equips us with knowledge to appreciate the intricate mechanisms that make our daily lives easier. CNC Milling
