Springs are an integral part of many mechanical systems, providing support and flexibility to numerous devices and appliances. From everyday objects like pens and chairs to complex machinery in industries such as automotive and aerospace, springs play a crucial role in various applications. In this article, we will delve into the different kinds of springs and explore their manufacturing processes and uses.

1. Torsion Springs:
Torsion springs are designed to store rotational energy when twisted or torsioned. These helical metal coils exert torque, which helps them resist twisting forces. Torsion springs find wide-ranging applications, from clothespins to garage doors and even clipboards. To produce these springs, CNC machining comes handy, where computer-controlled machines precisely shape the coil diameter, pitch, and pitch angle as per requirements.

2. Compression Springs:
Compression springs are the most common type of spring used extensively for absorbing shock or storing energy by compressing. They work on the principle of linear force application, meaning that they push back against an applied force. Found in suspension systems of vehicles, mattresses, trampolines, and more, compression springs can be manufactured through CNC machining as well. By feeding precise instructions into the machine, one can achieve accurate dimensions and coil spacing required for specific applications.

3. Extension Springs:
Extension springs, also known as tension springs, expand under a pulling force and regain their original shape once the force is removed. With loops at either end, they often find use in household items like garage door assemblies, balance scales, and various electrical devices. CNC machining ensures precision during production, allowing manufacturers to create extension springs with particular loop sizes while maintaining consistency across batches.

4. Tapered Springs:
Tapered springs possess a unique design where the coil thickness reduces towards one end. This configuration enables the spring to compensate for varying loads and provide consistent force levels. Commonly found in seat cushions, shock absorbers, and valves, these springs undergo CNC machining processes that involve tapering the coils to precise specifications.

5. Constant Force Springs:
Constant force springs are designed to provide a constant level of torque or tension throughout their working range. These springs find applications in tape measures, window mechanisms, and retractable cords, where reliable linear motion is required. Manufacturing constant force springs includes precision CNC machining techniques to ensure uniformity and consistent performance across the entire length of the strip.


From torsion to compression, extension to tapered and constant force springs, each type has its own unique design and purpose. CNC machining plays a crucial role in producing these diverse springs with accurate dimensions and properties necessary for specific applications. By understanding the different types of springs available and their respective manufacturing processes, engineers and manufacturers can create devices and systems that rely on springs for optimal functionality and reliability.
