CNC machining has revolutionized various industries by offering precision, efficiency, and versatility. One fascinating aspect of this technology is its ability to create intricate and complex parts, including different types of springs. In this article, we will delve into the world of springs and explore the various kinds that can be produced through CNC machining.

1. Compression Springs:

Starting with one of the most common types, compression springs are widely used for their ability to store energy when compressed. These springs are prevalent in numerous applications, such as automotive suspensions, appliances, industrial machinery, and much more. Using CNC machining, these springs can be precisely manufactured to meet specific size requirements, materials, and load-bearing capacities.

2. Extension Springs:

Unlike compression springs, extension springs elongate rather than compress. They work by absorbing and storing mechanical energy when pulled apart. These springs find applications in garage doors, trampolines, and various mechanical devices where tension or pulling forces need to be controlled. CNC machining allows for precise production, enabling customization of wire diameter, coil pitch, and end loop design according to individual needs.

3. Torsion Springs:

Torsion springs are designed to resist rotational or twisting forces. They store and release energy as they rotate back to their original position. Common examples include those found in clothespins, mousetraps, and vehicle suspensions. With CNC machining, torsion springs can be crafted to fit specific torque requirements, incorporating customized leg lengths, diameters, angular deflection rates, and even variations in wire thickness.

4. Constant Force Springs:

Constant force springs provide a steady, consistent force over their entire length, making them ideal for applications requiring smooth and continuous motion. These springs enable convenient coiling/uncoiling while delivering constant torque or tension. They find use in retractable cords, tape measures, window shades, and various mechanisms requiring controlled linear motion. CNC machining ensures precision in manufacturing these springs, allowing for consistent force output and customized sizes.

5. Wave Springs:

Wave springs are flourishing as a space-saving alternative to traditional coil springs. These flat wire springs can be used when limited axial space is available while achieving similar performance characteristics to compression springs. They find applications in automotive components, aerospace systems, medical devices, and even mechanical seals. CNC machining facilitates accuracy and repeatability during production, creating wave springs with specific dimensions and load capacities while maintaining their unique shape.


CNC machining has transformed the way different types of springs are manufactured, offering numerous advantages over conventional methods. From compression springs to extension springs, torsion springs, constant force springs, and wave springs, each type finds its application across diverse industries. With CNC technology, manufacturers gain precise control over dimensions, materials, customization options, and scalability.

The versatility and accuracy provided by CNC machining allow engineers and designers to create springs tailored to meet specific project requirements, ensuring optimal functionality and longevity. This advanced manufacturing process opens up new possibilities for innovation and efficiency in various sectors where springs play crucial roles.

As the demand for high-quality springs continues to grow, CNC machining stands as a robust solution capable of delivering superior results. By understanding the nuances and capabilities of this technology, engineers and manufacturers can harness its potential to produce top-notch springs that keep our machinery running smoothly, efficiently, and reliably.
