Springs are widely used in various industries, from automotive to aerospace, due to their ability to store and release mechanical energy. These versatile components come in a variety of types and forms, each specifically designed for different applications. In this article, we will delve into the world of springs and explore the different kinds available, their functions, and the CNC machining processes involved in producing them.

1. Compression Springs:
Compression springs are conical or cylindrical in shape and are designed to resist compression forces. They work by pushing back against an applied force, returning to their original position once the force is removed. Compression springs have widespread use in engines, pumps, suspensions, and even everyday items like pens.

To produce compression springs through CNC machining, a specialized spring coiling machine winds a wire around a mandrel, creating the desired pitch and diameter. The coiled spring is then cut to the appropriate length and ends are formed according to requirements.

2. Extension Springs:
Extension springs, also known as tension springs, are designed to stretch when a force is applied. As they extend, they absorb and store potential energy which is released when the force is removed. Extension springs find application in garage doors, trampolines, toys, and many other devices requiring controlled extension.

In CNC machining, extension springs are produced using similar methods to compression springs; however, instead of being wound tightly together, these springs are stretched during the winding process to achieve the desired specifications.

3. Torsion Springs:
Torsion springs operate based on rotational forces rather than linear compression or extension. When twisted, torsion springs exert a torque that opposes the applied force, bringing objects back to their neutral position. Commonly found in clothespins, door hinges, and balance scales, torsion springs provide crucial functionality in countless mechanisms.

Manufacturing torsion springs involves shaping metal wires using CNC machining equipment that precisely forms the spring into the required spiral or helical shape. The ends of torsion springs are typically attached to other components, allowing them to rotate and return to their initial position when the applied force is removed.

4. Die Springs:
Die springs are designed for heavy-duty applications involving high loads and stress conditions. Commonly used in stamping dies, clutches, brakes, and steering systems, die springs provide consistent performance even under extreme circumstances.

To manufacture die springs through CNC machining, larger diameter wires are coiled at specific compression ratios. Depending on the application requirements, die springs may have different configurations such as rectangular or square-shaped cross-sections.


Springs come in a wide variety of types and sizes to serve diverse industrial needs. Understanding the functions and characteristics of different kinds of springs is essential for selecting the appropriate one in any given application. CNC machining plays a vital role in fabricating these integral components, ensuring accuracy, precision, and durability.

Whether it's compression springs resisting forces, extension springs providing controlled extension, torsion springs offering rotational resistance, or die springs withstanding extreme pressure, the importance of springs in modern engineering cannot be overstated. With continuous advancements in CNC machining technology, the production of high-quality and customized springs has become increasingly efficient, benefitting various sectors worldwide.
