Springs are an essential component in various industries, including CNC machining. These mechanical devices play a vital role in absorbing energy, storing it, and releasing it when required, making them indispensable for many applications. In this article, we will delve into the different kinds of springs utilized in CNC machining processes and their importance.

1. Compression Springs:

Compression springs are widely used in CNC machining as they can resist compressive forces and return to their original length once the force is removed. Typically made from metal wire, these springs find extensive application in industrial machinery, automotive systems, and even household items like pens. They provide stability, ensure precision alignment, and absorb shocks effectively.

2. Torsion Springs:

Torsion springs store mechanical energy when twisted or rotated around their axis. The resistance created by these springs helps restore the system's position back to its original state after rotational or torsional movement. CNC machines employ torsion springs for components that require angular deflection, such as hinges, lever arms, and balance systems. The ability of torsion springs to exert torque makes them invaluable in achieving accurate and controlled movements within CNC machining equipment.

3. Extension Springs:

Extension springs function opposite to compression springs. Instead of resisting compressive forces, extension springs expand and store energy when extended. Upon release, they contract, returning to their initial position. Utilized in pneumatic cylinders, farm machinery, and countless other applications, extension springs assist in creating tension while ensuring smooth operation without compromising safety and reliability in CNC machining.

4. Constant Force Springs:

Constant force springs offer consistent linear motion and generate nearly uniform force throughout their working range. By providing equal force distribution over their extension, these springs enable efficient transfer of energy, minimizing stress concentrations. In CNC machining, constant force springs find utility in complex mechanisms where steady and reliable force is crucial, such as in counterbalancing systems and retractable devices.

5. Wave Springs:

Wave springs are a type of compression spring featuring waves or curves instead of traditional round coils. Designed to occupy minimal space while offering the same functionality as regular compression springs, wave springs excel at reducing axial height requirements. This compact design makes them suitable for CNC machining applications with limited spatial constraints. Their increased precision, reduced weight, and ability to handle high loads make wave springs ideal for various industries, including automotive, aerospace, and medical equipment.


Springs play an indispensable role in CNC machining processes, ensuring smooth and controlled movements, absorbing shocks, and maintaining system stability. From compression and torsion springs to extension springs, constant force springs, and wave springs, each type caters to specific needs within the manufacturing industry. The extensive use of these different kinds of springs highlights their significance in achieving accurate performance and reliability in CNC machines across various industrial sectors.

As technology continues to evolve, developers strive to enhance spring designs further, incorporating materials with superior strength, durability, and versatility. The ongoing advancements in spring technology are set to revolutionize CNC machining, enabling even more precise and efficient production processes in the future. CNC Milling CNC Machining
