Springs are incredibly versatile mechanical components used in a wide range of applications. Whether it's for storing energy, controlling motion, or absorbing shocks, springs play a crucial role in ensuring smooth and efficient operation across various industries. In this article, we will delve into different kinds of springs, their unique characteristics, and the manufacturing processes involved in producing them using CNC machining.

1. Compression Springs:
Compression springs are one of the most common types of springs found in everyday objects. As the name suggests, these springs compress when pressure is applied and return to their original form when the force is released. They are typically made by coiling high-strength steel wire around a cylindrical mandrel. The CNC machining process facilitates precisely calculating the necessary parameters, such as wire diameter, number of coils, and pitch, to achieve the desired spring rate and load-bearing capacity.

Applications: Compression springs find extensive usage in automotive suspensions, mattresses, industrial machinery, medical devices, and much more.

2. Tension Springs:
Tension springs, also known as extension springs, work opposite to compression springs. When stretched, they store potential energy that can be released upon retracting back to their original length. Tension springs often have hooks at both ends for easy attachment. Similar to compression springs, CNC machining assists in fabricating tension springs with precise dimensions to meet specific load requirements.

Applications: Garage door mechanisms, trampolines, exercise equipment, and farm machinery employ tension springs extensively.

3. Torsion Springs:
Torsion springs operate by twisting rather than compressing or extending. These springs exert rotational forces when subjected to angular deflection. Manufactured by winding wire tightly onto a rod, torsion springs must withstand considerable stress while maintaining flexibility. CNC machining enables accurate calculations for the required wire thickness and coil length to optimize elasticity and longevity.

Applications: Torsion springs are crucial components in clothespins, vehicle doors, mouse traps, and various mechanical assemblies that rely on rotational forces.

4. Constant Force Springs:
Constant force springs exhibit a unique characteristic of providing consistent force output throughout their deflection range. They consist of tightly wound steel strips often guided by an arbor or spool. CNC machining ensures precision during the manufacturing process, allowing for accurate strip thickness to achieve the desired constant force effect.

Applications: These springs are widely used in retractable cords, tape measures, window shades, and other devices requiring uniform force application.

5. Belleville Springs:
Belleville springs, also known as conical disc springs or washers, are conically shaped discs designed to endure high loads while maintaining spring functionality. These springs can be stacked or used individually, depending on the required force and deflection characteristics. CNC machining aids in producing belleville springs with precise angles and thicknesses, ensuring efficient energy storage.

Applications: Belleville springs find extensive usage in valves, clutch systems, ball bearings, electrical connectors, and heavy-duty equipment.


Springs are essential components across numerous industries, enabling smooth operation, shock absorption, and controlled motion. By understanding the different types and applications of springs, it becomes evident that CNC machining plays a critical role in their production. The accuracy and precision offered by CNC machines ensure the optimal design and fabrication of springs, resulting in enhanced performance and longevity. Whether compression springs, tension springs, torsion springs, constant force springs, or belleville springs, each type serves specific purposes, contributing to the efficiency and reliability of countless products and machinery.
