In the world of CNC machining, springs play a crucial role in various applications. These mechanical devices store and release energy to absorb shock or maintain pressure, making them indispensable components in industries such as automotive, aerospace, healthcare, and electronics. This article aims to shed light on different kinds of springs used in CNC machining, their production methods, and their diverse applications.

1. Compression Springs:
Compression springs are widely employed in CNC machining due to their ability to absorb and distribute force evenly when compressed. They are typically cylindrical and helical in shape, made from materials like stainless steel, carbon steel, or phosphor bronze. Producing compression springs involves coiling a wire around a mandrel using automated CNC machinery. The dimensions, number of coils, and pitch can be customized based on specific requirements. Applications include shock absorbers, buttons, valves, and suspension systems.

2. Torsion Springs:
Torsion springs find extensive use in CNC machining, especially where rotational force is required. As opposed to compression springs that absorb axial forces, torsion springs function by storing mechanical energy when twisted and releasing it upon being untwisted. Manufacturing torsion springs involves forming wire into a coil with legs at both ends, enabling rotational functionality. Customizations can be made concerning leg lengths, diameters, and torque strengths. Common applications for torsion springs include hinges, garage doors, brake pedals, and balance scales.

3. Extension Springs:
Extension springs are known for their ability to extend when pulled apart. They operate under tension rather than compression, offering resistance against external forces. In CNC machining, extension springs are fabricated by coiling the wire tightly around a mandrel and allowing it to create inclined loops. The arrangement determines the spring rate, which affects the force required to elongate the spring. Extension springs serve numerous purposes such as trampolines, door locks, medical devices, and curtain rods.

4. Constant Force Springs:
Constant force springs are distinguished by their consistent load characteristics throughout the entire extension range. They provide a nearly constant force despite changes in length, which makes them ideal for applications where uniformity is critical. CNC machining enables the creation of these springs using flat strips of material coiled onto a drum, exerting force as they unwind during use. Industries utilize constant force springs for devices such as tape measures, seat belts, window shades, and retractable cords.

5. Wave Springs:

Wave springs offer a space-efficient alternative to traditional coil springs due to their spiral design with waved edges. These precision springs maintain a similar force and deflection capability to larger compression or extension springs while occupying less axial space. CNC machining enables wave spring production using flat wire that is formed into a wave-like pattern. This process helps optimize space utilization and reduces overall weight, making wave springs suitable for miniature electronics, automotive suspensions, medical equipment, and valve assemblies.

Understanding the different types of springs used in CNC machining enhances our awareness of their versatility and importance across various industries. Whether it's the compressive nature of compression springs, rotational movement facilitated by torsion springs, resistance offered by extension springs, uniformity provided by constant force springs, or compactness achieved through wave springs – each type has distinct characteristics that serve specific purposes. The efficient production methods enabled by CNC machining ensure that these vital mechanical components are readily available to meet diverse engineering requirements across numerous fields.
