Springs are powerful mechanical devices that have been utilized for centuries to store energy or absorb shock. They come in various forms, each designed for unique applications. In this article, we will delve into the different kinds of springs available, their functions, and how CNC machining plays a crucial role in producing these essential components.

1. Compression Springs:

Compression springs are the most common type of spring used today. These helical-shaped coils are designed to resist compressive forces when pressure is applied at both ends. Compression springs find widespread use in automotive suspensions, industrial machines, and countless other applications where resistance to compression is required.

Producing Compression Springs:
To manufacture compression springs, precise measurements and dimensions are crucial. CNC machining comes into play during the wire-forming process, where advanced computer-controlled tools shape high-tensile steel wires into coiled springs based on specific designs and specifications. CNC lathes accurately form and cut the wire, ensuring consistent length and diameter, resulting in sturdy and reliable compression springs.

2. Extension Springs:

Unlike compression springs, extension springs operate in tension by resisting stretching forces. Often found in trampolines, garage doors, and farm machinery, extension springs work to bring objects back to their original position after being stretched.

Manufacturing Extension Springs:
CNC machining aids in effortlessly forming extension springs. Steel rods are fed into CNC-controlled cutting machines, which create precisely shaped hooks on both ends. The hooks give the extension springs their signature appearance while acting as attachment points.

3. Torsion Springs:

Torsion springs function similarly to compression springs but act upon rotational forces rather than linear ones. These springs exert torque or rotary force when twisted, making them ideal for applications requiring angular rotation, such as clock mechanisms and clothespins.

Producing Torsion Springs:
Creating torsion springs involves utilizing CNC lathes with specialized cutting tools. The lathes precisely bend and shape high-quality steel wires or bands, ensuring consistent dimensions and accurate configurations. CNC machines excel in producing complex torsion springs necessary for intricate devices like watches and automotive suspension systems.

4. Die Springs:

Designed to withstand heavy loads and extreme conditions, die springs are commonly used in the stamping and tooling industry. Their unique construction allows them to absorb high amounts of energy without deformation, making them ideal for repetitive applications.

Manufacturing Die Springs:
CNC machining plays a vital role in producing die springs by accurately forming and shaping rectangular-shaped wires or bars into tightly coiled and robust springs. With advanced computer programming, CNC machines achieve exceptional precision during both wire formation and final assembly processes.


Springs come in various forms and serve essential functions across numerous industrial sectors. Whether it's compression springs providing shock absorption or extension springs restoring objects to their original position, these versatile components play an integral role in countless mechanical operations.

Thanks to advancements in CNC machining technology, manufacturing springs has become a streamlined process. CNC-controlled machines ensure precise measurements, consistent dimensions, and properly shaped coils, ultimately yielding high-quality springs that meet specific design requirements.
