Springs play a crucial role in many industries, including CNC machining. These mechanical devices store and release energy to support various applications. From compression springs to extension springs, torsion springs to flat springs, the diversity in their types enables them to be utilized across different sectors. In this article, we will delve into the world of springs and explore their significance within the realm of CNC machining.

Compression Springs:

One of the most widely used types of springs in CNC machining is the compression spring. Found in automotive suspension systems, hydraulic valves, and other equipment, these springs are designed to oppose compressive forces. The production process involves utilizing specialized machinery capable of coiling steel wire while applying tension to achieve an extended shape. Once compressed, the stored energy can be released selectively when needed for various applications, ensuring smooth and controlled movements within CNC machines.

Extension Springs:

In CNC machining, extension springs come into play when there is a need to extend and return a component back to its original position. These springs counteract tensile forces by extending along the axis being pulled. Often found in garage doors, trampolines, or even surgical instruments, extension springs undergo specific manufacturing processes facilitating customization according to varying requirements. By introducing tension to the spring's material, it elongates until reaching equilibrium, providing the necessary force to restore balance and functionality in CNC machined parts.

Torsion Springs:

When dealing with rotational or twisting movements, torsion springs become indispensable in CNC machining. From body hinges in automobiles to clothespins and mouse traps, these springs offer a solution for applications requiring angular motion. The fabrication procedure starts by winding steel wire tightly around a mandrel, creating torque resistance. The angle of rotation is predetermined during their production, which allows torsion springs to store and release energy efficiently in conjunction with rotational motion within CNC machines.

Flat Springs:

Flat springs, also known as leaf springs, find extensive use within the CNC machining realm due to their flexibility and versatility. They are typically made from thin strips or sheets of material, such as steel, and can be found in various forms like cantilevered beams or multiple layers stacked together. They provide support, absorb shocks, or exert forces depending on the application's requirements. From automobile suspensions and electronic contacts to clutch drives and door locks, flat springs enhance the performance and efficiency of CNC machines by mitigating vibrations, redistributing stress, and maintaining stability.


In the world of CNC machining, springs play an integral role by providing crucial mechanical support, controlled movements, and stored energy transfer. Compression, extension, torsion, and flat springs embrace the diverse challenges encountered in this industrial sector. By understanding the unique characteristics and manufacturing processes of these springs, professionals in CNC machining can harness their potential for smoother operations, optimized functionality, and enhanced overall performance.

Therefore, incorporating the correct type of spring into CNC machines leads to improved outcomes, increased precision, and reduced wear and tear of components. As technology continues to evolve, so does the demand for advanced spring designs catering to the ever-growing complexities within CNC machining. Harnessing the power of different spring types ensures that industries can push boundaries and achieve greater heights of innovation in this dynamic field. CNC Milling
