In the realm of mechanical engineering, springs play a vital role in many applications. Springs are elastic devices that store mechanical potential energy when compressed or stretched and release it upon returning to their original state. They are widely used in various industries, including CNC machining. In this article, we will delve into different kinds of springs and understand how they contribute to the precision and efficiency of CNC machining processes.

1. Compression Springs:
Compression springs are one of the most common types of springs used in CNC machining. These springs are designed to resist compression forces and return to their original shape when the applied force is released. They find wide usage in automotive components, aerospace equipment, machinery, and more. CNC machines employ compression springs for applications like damping vibrations, providing stability, and maintaining uniform pressure during cutting operations.

2. Torsion Springs:
Torsion springs work by twisting or exerting torque rather than compressing or stretching. Due to their unique design, these springs store and transmit rotational energy, allowing them to withstand bending moments. In CNC machining, torsion springs can be found in rotary tools, clamps, and feedscrews to ensure controlled motion, axial alignment, and precise positioning of equipment.

3. Extension Springs:
Extension springs operate through extension and contraction due to tension forces acting on their helical coils. The ability to resist pulling forces makes these springs highly valuable in CNC machining, where they are commonly employed to counterbalance heavy loads, maintain tension for belts and pulleys, and assist in the movement of movable components.

4. Constant Force Springs:
Constant force springs offer a consistent level of force throughout their entire range of extension. These springs have a tightly wound coil with a strip of pre-stressed material. Within CNC machining, constant force springs are frequently utilized for tasks such as retractable safety guards, cable management systems, and counterbalancing mechanisms. Their ability to exert constant force helps maintain smooth and uninterrupted movement, enhancing precision in machining operations.

5. Wave Springs:
Wave springs are a type of compression spring characterized by their wave-like appearance instead of traditional coil shapes. They occupy less axial space compared to regular springs while providing similar performance characteristics. CNC machining applications often benefit from employing wave springs due to their capability to compensate for dimensional variations, absorb vibrations, and reduce overall weight within confined spaces.

6. Belleville Springs:
Belleville springs, also known as disc springs or conical washers, consist of multiple disk-shaped cones stacked together. These springs can handle high loads within limited spaces. CNC machines utilize Belleville springs for applications such as clamping systems, pressure relief valves, shock absorption, and compensating for thermal expansion or contraction. Their reliability, compact design, and ability to generate substantial forces make them invaluable in various mechanical setups.


Springs play an integral role in the world of CNC machining, offering stability, precision, and load management across diverse applications. From compression springs that resist compressive forces to torsion springs that transmit rotational energy, the right choice of spring in CNC machining processes contributes significantly to the efficiency and accuracy of operations. By understanding the different types of springs available, engineers can optimize machining tasks, improve component performance, and enhance overall productivity in this dynamic field. CNC Milling
