Springs are essential components used in various industries, including CNC machining. These mechanical devices store potential energy and release it when a force is applied, making them invaluable for achieving precision and efficiency in many applications. In this article, we will delve into the different types of springs commonly utilized in CNC machining processes, highlighting their characteristics and functions.

1. Compression Springs:
Compression springs are perhaps the most well-known type of spring. They are typically open-coiled and work by compressing under a load to provide resistance or absorb shock. Constructed from materials such as steel, stainless steel, or even specialized alloys, compression springs find extensive use in CNC machining, ranging from precision machinery to automotive parts. The design flexibility of compression springs ensures optimal performance in numerous challenging environments.

2. Torsion Springs:
Designed to resist twisting forces, torsion springs generate torque and offer angular deflection while subjected to rotational movement. These helical springs commonly have arms attached at opposite ends, allowing them to exert a rotational force over moments of rotation. With CNC machining, torsion springs can be employed to create precise movements and ensure smooth operation in various systems like door hinges, balance mechanisms, and electrical switches.

3. Extension Springs:
Unlike compression springs, extension springs expand in response to an axial pulling force. When stretched, they store energy, and upon release, return to their original position. This type of spring is widely used in CNC machining, especially in applications that involve consistent tension loads, such as trampolines, garage doors, or industrial machinery requiring linear force. Extension springs come in different sizes and configurations depending on the specific requirements of the project.

4. Constant Force Springs:
Constant force springs deliver a continuous level of force throughout their range of motion. These flat, prestressed coils eliminate variations in force as the spring extends or retracts. This remarkable characteristic makes constant force springs ideal for applications requiring a smooth, precise motion, such as high-speed feeding systems in CNC machining. They can withstand repetitive stress without compromising performance, making them suitable for use in various industries.

5. Belleville Springs:
Belleville springs, also known as disc or conical springs, have a unique shape that allows them to exert an axially opposing force when compressed. The stacked disc configuration provides highly predictable and consistent spring characteristics, ensuring reliable operation even under extreme conditions. In CNC machining, Belleville springs find utilization in clamping mechanisms, electrical contacts, and adjustable pressure relief valves where compact size, high load capacity, and stability are crucial.


From compression and torsion springs to extension and constant force springs, the array of options available in CNC machining allows manufacturers to choose the most appropriate spring type for their specific needs. Each type offers distinct benefits pertaining to factors like energy storage, resistance capabilities, or intricate mechanical movements. By understanding the different kinds of springs and their applications within CNC machining processes, industry professionals can optimize precision, efficiency, and overall quality in their manufacturing operations.
