Springs are a fascinating engineering marvel that has been utilized in various industries for centuries. These mechanical devices possess an innate ability to store energy and release it when required, making them indispensable across numerous applications. In this article, we will delve into the different kinds of springs, their production techniques, and explore some intriguing applications where they play a pivotal role.

Overview of Different Kinds of Springs:

1. Compression Springs:
Compression springs are widely used due to their versatility and compact design. They work by compressing under a load and returning to their original shape once the force is removed. Regularly found in automotive suspensions, mattresses, valve assemblies, and industrial equipment, compression springs provide resistance against compression forces.

2. Extension Springs:
Extension springs operate in the opposite manner as compared to compression springs. They stretch, or extend, when subjected to a load and attempt to return to their original configuration upon force withdrawal. You can often find extension springs in trampolines, garage doors, balance scales, and various types of machinery, assisting in counterbalancing weights or storing energy.

3. Torsion Springs:
Torsion springs rely on twisting motion rather than linear compression or extension. Designed to exert torque, these springs absorb or dissipate rotational energy. Examples of torsion springs include mouse traps, clothespins, door hinges, and various vehicle suspension components – all requiring rotational movement control.

4. Constant Force Springs:
Constant force springs offer a unique advantage by maintaining a relatively constant force throughout deflection. As they uncoil from a spooled design, they efficiently deliver a consistent force over extended distances. Commonly used in tape measures, retractable pens, window shades, and motorized systems, these springs ensure smooth and controlled operation in countless mechanisms.

Producing Different Types of Springs using CNC Machining:

CNC (Computer Numerical Control) machining is an advanced manufacturing technique widely employed in producing springs with high precision and efficiency. Here's a general overview of how different types of springs can be produced using CNC machining:

1. Compression Springs:
CNC coiling machines wind wire around a mandrel to produce tightly spaced coils, which determines the spring's compression characteristics. The programming ensures accurate measurements, controlling the required pitch, diameter, number of coils, and overall stiffness.

2. Extension Springs:
Similar to compression springs, CNC coiling machines form extension springs by winding wire around specific mandrels. By manipulating variables such as wire gauge, coil diameter, initial tension, and overall length, precise control over spring properties is achieved during the CNC machining process.

3. Torsion Springs:
CNC machines employ a rotating mandrel to twist wire into torsion springs' desired configuration. Through precise rotational movements, the machine controls variables like leg length, wire diameter, total body length, and angle of rotation to customize each torsion spring for its intended application.

4. Constant Force Springs:
CNC machining allows for the production of constant force springs by accurately pre-winding a ribbon or strip of material onto a spool. As the spring unwinds, it imparts equal force throughout its travel due to controlled friction between the layers. A CNC assembly ensures consistent thickness and proper alignment of these layered ribbons, achieving desired performance parameters.

Applications of Springs and Their Benefits:

Springs find diverse applications across multiple industries due to their unique characteristics. Some notable areas where springs prove indispensable include:

1. Automotive Industry: Suspension systems rely on various types of springs for stability, shock absorption, and smooth ride quality.

2. Aerospace Industry: Springs play a crucial role in landing gear assemblies, ensuring smooth aircraft touchdown and handling extreme loads during take-off and landing.

3. Medical Devices: Implants, surgical instruments, and prosthetics often incorporate miniature springs to enable precise movement and optimal functioning.

4. Consumer Goods: Springs contribute to the smooth operation of everyday items such as kitchen appliances, toys, writing instruments, and furniture.


Springs are an essential component in countless devices, providing motion control, energy storage, and precision functionality across numerous industries. By understanding the characteristics and production methods of different springs, we gain insight into their versatile applications. Utilizing CNC machining techniques ensures accurate and efficient production, enabling springs to perform optimally within complex mechanisms globally. CNC Milling
