Springs are an essential component used in a wide range of industries and applications. From automotive to aerospace, manufacturing to medical, springs serve as vital elements for ensuring smooth functioning and providing stability or elasticity. In this article, we will explore the different kinds of springs utilized across industries, their unique characteristics, and how CNC machining plays a significant role in their production.

1. Compression Springs:

Compression springs are one of the most common types of springs widely employed in various mechanisms requiring resistance to compressive forces. These springs absorb and store energy when compressed and release it when extended. Manufactured in a variety of shapes and sizes, compression springs find extensive use in automotive suspension systems, valves, electrical appliances, and construction equipment.

To produce compression springs, CNC machining is often utilized. Starting with raw materials such as stainless steel wire, CNC machines can precisely form the wire into the desired shape, allowing manufacturers to create compression springs tailored to specific requirements with high accuracy and repeatability.

2. Tension Springs:

Tension springs operate under tensile stress, exerting force when pulled apart. Commonly referred to as extension springs, they find application in garage doors, trampolines, mechanical components, and even certain surgical instruments. The versatility of tension springs lies in their ability to resist pulling forces while remaining compact and efficient.

CNC machining enables the creation of tension springs through intricate processes involving precise bending and shaping of wires or strips. With the assistance of computer-controlled machinery, spring manufacturers can achieve consistent results, ensuring the load-bearing capacity and longevity of tension springs.

3. Torsion Springs:

Requiring torque rather than linear movement, torsion springs exhibit their unique properties when subjected to twisting or rotational motion. They store mechanical energy when twisted and release it upon returning to their original position. Applications utilizing torsion springs include clothespins, mouse traps, balance scales, and various automotive components.

The production of torsion springs often involves CNC machining to form the desired shape. By utilizing state-of-the-art technology, spring manufacturers can accurately design and fabricate torsion springs with specific torque requirements. This precision ensures reliable functionality and enables smooth operations in diverse applications.

4. Constant Force Springs:

Constant force springs are designed to exert a consistent force throughout their extension or compression range, providing a steady supply of power. They find use in retractable cables, counterbalances, tape measures, and other devices requiring uniform force output over extended periods.

CNC machining plays a crucial role in producing constant force springs by enabling precise coiling techniques. Using programmable machinery, manufacturers can create tightly wound springs with consistent dimensions, ensuring predictable and reliable performance.


Springs play a fundamental role in countless industries and applications, offering stability, elasticity, and controlled energy storage/release mechanisms. Whether it is compression, tension, torsion, or constant force springs, CNC machining allows manufacturers to produce these vital components with exceptional precision and accuracy. With this advanced technology, spring manufacturers can deliver tailored solutions that meet the unique requirements of different industries while ensuring reliable operation and longevity.
