Springs are ubiquitous in our everyday lives, found in various applications ranging from small mechanisms to complex industrial systems. Whether it's a clock spring or a suspension spring in your vehicle, these mechanical devices serve as integral components in many products and systems. In this article, we delve into the fascinating world of springs, examining the different types available and exploring their manufacturing process.

Understanding Different Types of Springs:

1. Compression Springs:
Compression springs are perhaps the most common type of spring. Their primary purpose is to provide resistance to compressive forces when applied at their ends. Such springs can be manufactured with various wire sizes and diameters, allowing for a wide range of load capacities. Frequently used in automotive suspension systems, mattresses, and switches, compression springs are vital for absorbing shocks and maintaining equilibrium.

2. Extension Springs:
Extension springs work oppositely to compression springs by expanding when subjected to tensile force. These springs store potential energy, which they release when the extending force is removed. Common applications include trampolines, garage doors, and exercise equipment.

3. Torsion Springs:
Torsion springs transmit rotary motion between two surfaces by exerting torque along its rotation axis. For example, torsion springs can be found in clothespins, mousetraps, and even clipboards, where they provide the necessary tension to hold papers in place.

4. Clock Springs:
Also known as spiral springs, clock springs find extensive use in winding mechanisms such as that found in watches and clocks. The tightly wound coils generate torque while unwinding, enabling precise timekeeping.

Producing Springs – The CNC Machining Process:

Computer Numerical Control (CNC) machining has revolutionized the production of various mechanical parts, including springs. Here's how CNC machining plays a crucial role in the manufacturing of springs:

1. Design and Programming:
Firstly, the design of a spring is created using computer-aided design (CAD) software. The parameters such as wire size, coil diameter, and pitch are determined based on the specific requirements of its application.

Next, the CAD design is translated into machine-readable instructions through Computer-Aided Manufacturing (CAM) software. This programming stage provides precise dimensions, tolerances, and tooling requirements for CNC machines.

2. Material Selection:
Choosing the right material is crucial to ensure the desired properties of the spring, including strength, elasticity, and resistance to corrosion or fatigue. Common materials used in spring manufacturing include stainless steel, carbon steel, brass, and titanium.

3. CNC Spring Coiling Machines:
CNC spring coiling machines automatically feed the chosen material into the machine, which then shapes it according to the programmed design. These machines utilize a combination of rotating mandrels, cutting tools, and servo motors to produce springs with consistent dimensions and characteristics.

4. Heat Treatment and Finishing:
After the initial shaping process, springs may undergo heat treatment like tempering or quenching, depending on the material used. Heat treatment improves the spring's mechanical properties, enhancing its resilience and durability.

Subsequently, finishing steps such as shot peening or surface coating may be employed to further enhance performance, corrosion resistance, or aesthetics.


Springs play an essential role in countless devices and systems that we encounter daily. Understanding the different types of springs enables us to appreciate their versatility and broad range of applications. With CNC machining technology, the production of springs has become highly efficient and customizable, allowing manufacturers to meet specific requirements and maintain consistent quality across various industries.
