Springs play a crucial role in various industries, providing elasticity and resilience to countless products and systems. They are widely used for their ability to store potential energy and release it when needed. In this article, we will delve into the different kinds of springs, their diverse applications, and briefly touch upon how CNC machining contributes to the production process.

1. Compression Springs:
Compression springs are among the most common type of springs, found in numerous everyday items. They work by compressing under load and efficiently absorbing shock or maintaining tension between two components. These springs can be tailored to suit specific applications, such as automotive suspensions, industrial machinery, toys, and even mattresses.

To produce compression springs, manufacturers utilize CNC machining processes to shape and cut individual coils from wire materials like steel, stainless steel, or alloy. The precision provided by CNC technology ensures consistent spring dimensions and strength.

2. Extension Springs:
Extension springs, also known as tension springs, serve an opposite purpose to compression springs. They elongate under load and create resistance that pulls objects back together once the force is relieved. Extension springs find usage in trampolines, garage doors, balance scales, and many other devices requiring controlled extension and retraction.

CNC machining enables efficient fabrication of extension springs by forming tightly wound coils around mandrels. Once again, the accuracy offered by CNC equipment contributes to tailoring these springs based on specific requirements.

3. Torsion Springs:
Torsion springs operate through rotational motion, applying torque between two objects. These springs resist twisting forces while storing and releasing energy. Their widespread use includes mouse traps, clothespins, and various mechanical assemblies where rotational force is desired.

When producing torsion springs, CNC machining allows intricate winding configurations for precise torque delivery. This method facilitates customization, resulting in springs with accurate angles and loads suitable for specific applications.

4. Constant Force Springs:
Constant force springs ensure an even force is exerted over a long distance, without directly depending on the compression or extension properties. Usable in tape measures, counterbalances, and retractable cords, these springs offer consistent tension while accommodating significant deflection.

CNC machining allows manufacturers to produce constant force springs with engineered variations in coil pitch or thickness along their length. This precision ensures reliable performance across extended periods of usage.

5. Wave Springs:
Wave springs are designed as alternatives to traditional coil springs, offering multiple turns in a compact package. They reduce height requirements in various applications where space is limited while providing high load capacity and deflection.

Producing wave springs involves CNC machining techniques that cut stainless steel strip materials into specific shapes. The accuracy offered by CNC equipment enables precise customization for diverse industrial uses, including aerospace, medical devices, and robotics.


Springs in their myriad forms can be found in countless products that we use daily. From compression and extension springs to torsion, constant force, and wave springs, each type has its unique purpose and application. CNC machining plays a crucial role in producing these springs, ensuring their dimensions, strength, and customizability meet stringent industry standards. Whether it's maintaining tension, absorbing shock, providing torque or consistent force, springs are essential components that contribute to the functionality of numerous systems around us.
