Springs are an essential component used in various industries, including CNC machining. These versatile mechanical devices are designed to store energy and release it when required, making them an invaluable part of many applications. From compression springs to torsion springs, this article delves into the different kinds of springs commonly used in CNC machining and how they contribute to the overall functionality of these precision machines.

1. Compression Springs:

Compression springs are one of the most common types of springs found in CNC machining. They are typically made from materials such as stainless steel, ensuring durability and resistance against corrosion. These springs work by compressing under a load and expanding back to their original shape when the force is released. In CNC machinery, compression springs are vital for absorbing shocks, maintaining pressure, and providing stability.

2. Extension Springs:

Extension springs operate on the principle of tension and are widely used in CNC machining. As the name suggests, these springs extend when a force is applied and retract when the load is removed. Extension springs are critical in balancing forces or storing energy within CNC machinery. They help to compensate for any expansion or contraction that may occur due to temperature variations, thereby ensuring smooth operation.

3. Torsion Springs:

Torsion springs are specifically designed to withstand rotational forces. They provide torque and assist in controlling motion in CNC machines. Torsion springs function by exerting rotary force or displacement proportional to the applied amount of torque. With their ability to absorb angular or twisting movements, torsional springs play a crucial role in maintaining precise alignment and stability during CNC machining processes.

4. Belleville Washers/Disc Springs:

Belleville washers, also known as disc springs, are unique spring-like devices used extensively in CNC machining equipment. These conical-shaped springs offer high load capacity with minimal deflection. Their primary purpose is to provide uniform pressure distribution and resist bolt loosening, ensuring secure fastening without compromising the structural integrity of CNC machinery.

5. Constant Force Springs:

Constant force springs are designed to exert a consistent force over their entire range of motion. These springs find extensive use in applications where counterbalancing weight is crucial, such as tool holders or cable management systems within CNC machinery. Their ability to maintain constant tension enhances performance by reducing wear, minimizing fatigue, and preventing excessive strain on moving parts.

6. Wave Springs:
Wave springs are unique due to their distinctive wavy shape. Manufactured from flat wire, these compact springs offer significant space-saving advantages compared to traditional coil springs. They are often employed in CNC machining where axial space constraints are prevalent. By providing comparable spring rates in reduced spaces, wave springs enable designers to optimize machine designs while maintaining desired functionality.


In CNC machining, springs play a vital role in ensuring smooth operation, reducing vibrations, compensating for temperature variations, and restoring machines to their original position after application of external forces. Understanding the different kinds of springs available helps engineers and machinists select the most suitable option for specific applications, optimizing overall productivity and reliability. From compression springs and extension springs to torsion springs, Belleville washers, constant force springs, and wave springs, each type serves a distinct purpose in enhancing CNC machining processes.
