Springs, an essential component found in various mechanical systems, play a vital role in absorbing and storing energy. From everyday objects to complex machinery, springs are utilized across industries for their unique capability to provide tension or compression force when subjected to external pressure or load. In this article, we delve into the fascinating world of different kinds of springs, their functionalities, and the diverse applications they cater to.

1. Compression Springs:

One of the most common types of springs, compression springs are designed to resist compressive forces by squeezing together. These springs store potential energy when compressed and release it when the load is removed. Used in automotive suspensions, valves, compressors, and more, compression springs provide stability, absorb shock, and ensure proper alignment. Their production involves specialized CNC machining processes where wire is formed and coiled to create the desired shape and dimensions.

2. Extension Springs:

Unlike compression springs, extension springs work by extending or stretching apart when subjected to axial loads. When pulled, these springs provide return force, returning to their original size. Widely used in trampolines, garage doors, toys, and agricultural equipment, extension springs require accurate calculations during CNC machining to ensure optimal tension and reliable performance.

3. Torsion Springs:

Torsion springs, as the name suggests, utilize rotational force to generate torque when twisted. These springs store mechanical energy and release it when untwisted. They find applications in computer keyboards, door hinges, vehicle suspensions, and industrial clamps, among others. Precision CNC machining allows for efficient production of torsion springs, ensuring precise angles and consistent torque values.

4. Belleville Springs:

Belleville springs, also known as disc springs or conical spring washers, have a distinctive shape featuring a cone-like design with a profile similar to a washer. These springs are characterized by their capacity to provide high loads in tight spaces. They are commonly used in bolted connections, valves, and electrical applications where rapid movement or vibration occurs. The CNC machining process for these springs involves precise shaping of metallic discs, taking into account the desired load and deflection characteristics.

5. Constant Force Springs:

Constant force springs maintain a consistent force throughout their extension or contraction, which makes them ideal for applications requiring uniform motion. These springs find utility in retractable cords, window blinds, tape measures, and cable management systems. CNC machining ensures precision fabrication of these springs by precisely coiling material layers to achieve the desired constant force properties.

6. Wave Springs:

Wave springs offer an innovative solution compared to traditional springs due to their compact size and increased axial space efficiency. With their unique wave-like shape, these springs reduce height requirements while providing considerable forces. Precision manufacturing techniques such as CNC machining enable efficient production of wave springs with accurate dimensions required for demanding applications like medical devices, aerospace mechanisms, and electrical connectors.


Springs serve as essential elements in numerous mechanical systems, ensuring smooth operation, stability, and energy absorption. Through the utilization of CNC machining processes, various kinds of springs can be accurately manufactured, catering to specific needs across industries. Whether it's compression springs, extension springs, torsion springs, Belleville springs, constant force springs, or wave springs, each type offers its own set of capabilities to meet diverse mechanical demands. Understanding and implementing the correct spring type enhances the performance, safety, and reliability of countless products we encounter in our daily lives. CNC Milling CNC Machining
