When it comes to CNC machining, springs play a crucial role in various applications. They enable machines to operate efficiently by exerting force, absorbing shock, or maintaining balance. In this article, we will delve into the different kinds of springs used in CNC machining and explore their diverse applications.

1. Compression Springs:
Compression springs are among the most common types of springs utilized in CNC machining. These helical springs are designed to resist compression and return to their original length when the applied force is removed. This makes them ideal for applications where machines require an energy-absorbing element or need to maintain pressure. Examples include clamps, valves, and suspension systems.

2. Torsion Springs:
Torsion springs function by resisting twisting forces. Designed to store and release rotational energy, they find extensive application in CNC machining. Torsion springs are often used in automated doors, hinges, and electric motors, where torque needs to be generated or cushioned. With their ability to provide angular movement, these springs ensure smooth operation and assist in precise positioning.

3. Extension Springs:
Extension springs differ from compression springs as they apply a pulling force rather than absorb compression. With an ability to extend under load and return to their original position, extension springs are perfect for applications that involve tension or pulling actions. In CNC machining, they are commonly found in garage door assemblies, trampolines, and various mechanical devices requiring extra grip or flexibility.

4. Constant Force Springs:
Constant force springs are specialized springs that generate constant tension throughout their deflection range. Unlike traditional springs, these coils unwind during use, providing a steady force without losing strength. Within CNC machining, constant force springs are critical components in retractable safety belts, tape measures, and even precision coil winding machinery. Their consistent force output ensures reliable performance over extended periods.

5. Belleville Springs:
Belleville springs, also known as disc springs or conical spring washers, are unique in their concave shape. These conically shaped springs are stacked together to generate high force within a small space. In CNC machining applications that require significant axial loading and vibration damping, such as stamping dies and clutch mechanisms, belleville springs offer excellent stability, resilience, and load-bearing capabilities.

6. Wave Springs:

Wave springs provide precise control between the loaded condition and free height. With a flat wire design featuring multiple waves, they offer comparable performance to traditional compression springs while occupying less axial space. In CNC machining, wave springs excel in applications where space constraints demand compactness without compromising on tension requirements. Examples include bearing preloads, valve actuation, and medical devices.

As we have seen, springs play a vital role in CNC machining, enabling machines to function optimally by providing necessary forces, absorbing shock, and maintaining balance. Whether it's compression springs for energy absorption, torsion springs for rotational movement, or extension springs for pulling actions, each type serves a specific purpose, contributing to the seamless operation of CNC machinery. Constant force springs, belleville springs, and wave springs further widen the scope of possibilities, catering to specialized requirements. By understanding the different kinds of springs available, manufacturers can select the most suitable options for their CNC machining needs, ensuring efficiency, reliability, and precision in their operations.
