Springs play an integral role in numerous mechanical devices and systems today. They are essential components that store mechanical energy, absorb shock or impact, and help maintain balance and stability. From industrial machines to everyday products, various types of springs are used for different purposes. In this article, we will explore the fascinating world of different kinds of springs, their functions, and how CNC machining contributes to their production.

1. Compression Springs:
Compression springs are one of the most common types of springs found in countless applications. As the name suggests, these springs compress under force and return to their original shape when the load is released. They are typically found in automotive suspensions, mattresses, ballpoint pens, and even pogo sticks. CNC machining enables the precise manufacturing of compression springs by cutting and forming wire into coils according to specific requirements.

2. Tension Springs:
Tension springs work in direct opposition to compression springs. When extended or stretched, tension springs generate a force that restores them to their original position. These springs find applications in garage doors, trampolines, industrial equipment, and various other mechanisms that require pulling forces. Through CNC machining, tension springs can be produced with carefully controlled dimensions and mechanical properties, ensuring optimal performance and longevity.

3. Torsion Springs:
Torsion springs operate differently from compression and tension springs as they twist or rotate along their axis to exert force. They have ends with arms or legs acting as levers, which enable them to store rotational energy. Common uses of torsion springs include vehicle suspensions, clothespins, wind-up toys, and even mousetraps. The precision offered by CNC machining ensures the reliable production of torsion springs by accurately twisting and shaping the wire to handle torsional loads effectively.

4. Constant Force Springs:
Constant force springs provide a continuous force output throughout their deflection, making them ideal for applications requiring smooth and consistent force delivery. These springs are commonly used in retractable tape measures, window blinds, conveyor systems, and various other mechanisms that require constant tension. CNC machining techniques aid in producing constant force springs with precise dimensions and controlled properties to deliver reliable performance.

5. Leaf Springs:
Leaf springs consist of multiple layers or leaves stacked on top of each other, with the longest leaf at the bottom providing stability and load-bearing capacity. They find extensive use in suspension systems of vehicles such as trucks, trailers, and agricultural equipment. CNC machining enables accurate cutting, shaping, and forming of leaf springs to ensure their durability, strength, and proper flexing capabilities under heavy loads.

6. Belleville Springs (Disc Springs):
Belleville springs, also known as disc springs, consist of conically shaped discs stacked together. They possess high spring rates and provide excellent load distribution, making them suitable for applications that require compact form factors, such as clutches, valves, bolted connections, and safety relief valves. CNC machining aids in manufacturing Belleville springs by accurately stamping, cutting, or etching the required shapes from flat sheets of metal materials.


Springs offer invaluable mechanical advantages across a wide range of industries and products, enabling enhanced functionality, resilience, and safety. Whether it's compression, tension, torsion, constant force, leaf, or Belleville springs, precision manufacturing through CNC machining ensures optimal performance, longevity, and reliability. The versatility of different kinds of springs is only made possible by the intricacies involved in their production, where CNC machining plays a significant role in achieving consistently superior quality and tailored specifications.
