In the world of manufacturing, particularly in the field of CNC machining, springs play a crucial role. These elastic mechanical devices store potential energy and are widely used across various industries for several applications. Understanding the different types of springs and their specific uses is essential to ensure optimal product performance and safety. In this article, we will delve into the intricacies of springs and explore how they are employed in the realm of CNC machining.

1. Compression Springs:

Compression springs are one of the most commonly used springs in CNC machining. They are designed to resist compression forces and provide resistance when compressed. These springs enable controlled pressure release between two components, maximizing efficiency and preventing damage due to excessive force or vibrations. Typically used in automotive suspensions, valves, and industrial machinery, compression springs excel at absorbing shock and maintaining stability.

2. Torsion Springs:

Torsion springs, as the name suggests, store energy by twisting or torsion. These springs exert rotational force, allowing them to store substantial amounts of energy within compact spaces. Commonly found in garage doors, clothespins, and electrical switches, torsion springs offer reliable rotational equilibrium and generate torque when subjected to angular displacement. CNC machines utilize torsion springs in various mechanisms that require rotary actuation, such as grippers and hinges.

3. Extension Springs:

Extension springs operate on the principle of extending or expanding under tension forces. These springs work opposite to compression springs, applying a pulling force instead of resisting compressive loads. Found in trampolines, door locks, and various industrial equipment, extension springs absorb and store energy when pulled apart and maintain tension to hold objects together securely. CNC machines often employ extension springs in tool holders, cable management systems, and retractable mechanisms.

4. Flat Springs:

Flat springs, also known as clock springs or leaf springs, consist of flat strips of metal that provide elasticity when bent or flexed. These springs offer advantages such as compactness, even distribution of forces, and a wide range of applications. CNC machining relies on flat springs for various purposes, including brush contacts in electrical devices, automotive fuel nozzles, and adjustable brackets.

5. Constant Force Springs:

Constant force springs ensure uniform pressure over their entire length, regardless of displacement. This unique characteristic makes them popular in applications where consistent tension is required, like cable management systems, tape drives, and counterbalances. In CNC machining, constant force springs find utility in providing linear force for critical components within the machine's intricate mechanisms.


Springs play an indispensable role in CNC machining, with each type serving specific functions to optimize mechanical performance and productivity. From compression and torsion springs to extension and flat springs, the assortment of these elastic devices enables smooth operation across diverse industries. Understanding the distinctive attributes and applications of different types of springs empowers manufacturers to make informed decisions regarding suitable choices for their CNC machines.

When selecting springs for CNC machining projects, it is crucial to consider factors such as load capacity, spring rate, materials, and environmental conditions. Collaborating with experienced engineers and spring manufacturers can help ensure precise customization, enhanced safety, and optimal performance for your CNC machined products.

Remember, the versatility and dependability of springs make them vital components in the ever-evolving world of CNC machining, enabling precision motion control, efficient energy storage, and improved overall functionality. CNC Milling CNC Machining
